A draft bill that proposes to create the 45,455-acre Dolores River National Conservation Area and a 10,828-acre special management area would prohibit certain activities but also protect existing uses.
The proposed special land designations are in Dolores and San Miguel counties in Southwest Colorado. The bill was drafted by U.S. Sen. Michael Bennet in cooperation with the two counties. A 45-day comment period began Monday. The draft has not been introduced in the Senate.
Generally, the NCA stretches about 61 miles along the Lower Dolores River corridor on Bureau of Land Management land from Bradfield Bridge to Little Gypsum Bridge.
It also would include the side drainages of Summit and McIntyre Canyons, which are southwest and northwest of Slick Rock.
What is allowed?
New mining, new roads and commercial timber harvesting would be prohibited, as well as new large dams. Motorized vehicles would be restricted to existing routes.
Large-scale water development outside the NCA would not be allowed if it diminished the scenic, recreational, and fish and wildlife values of the NCA.
Valid existing mining leases would be allowed. Water rights, grazing rights, private property rights would not be affected, according to bill language.
According to the bill, the purpose of the Conservation Area is to “conserve, protect and enhance the native fish, whitewater boating, recreational, scenic, cultural, archaeological, natural, geological, historical, ecological, watershed, wildlife, educational and scientific resources.”
If passed, a management plan must be drawn up within three years for the long-term protection, management and monitoring of the NCA.
Water Rights: The NCA designation and special management area do not include a water right.
According to the draft bill, water rights would be protected and operations of McPhee Reservoir would not be affected by the NCA. McPhee Reservoir would continue to operate under the Bureau of Reclamation and Dolores Water Conservancy District.
The NCA would allow the construction of small diversion dams or stock ponds. It also would allow for new minor water developments or modification of existing structures.
The NCA would not affect any existing water resource facility, including irrigation and pumping facilities, reservoirs, water conservation works, canals, ditches, pipelines, wells, hydropower projects, power lines, water diversion, storage and carriage structures. It also would not impede access to facilities for operation, maintenance, repair or replacement…
McPhee dam releases: Managed releases from McPhee Dam for whitewater boating and native fish populations would not be affected by the NCA, according to the bill.
For 10 years, boaters, fishery managers and water managers have improved cooperation on how best to manage limited releases for various recreation and ecological benefits. The bill calls for that to continue.
It also would require the Bureau of Reclamation to prepare and make publicly available a report that describes any progress with respect to the conservation, protection and enhancement of native fish in the Dolores River.
The NCA would not “alter or diminish” operations of the Dolores Project, which includes McPhee Dam, according to the draft bill. It would not affect treaty rights of the Ute Mountain Ute Tribe.
Wild and Scenic River: If the bill is passed, the BLM would drop a section of the Dolores River’s eligibility status for federal designation as a National Wild and Scenic River designation.
A designation of wild and scenic rivers can include a federally reserved water right. Water and county officials have advocated to eliminate the eligibility for a wild and scenic river because of concerns that upstream McPhee Reservoir could be eyed as a potential source for the water right.
Mining: The NCA preserves valid existing leases for mining within the boundaries, and leases may be extended. No new mining patents or leases would be allowed.
Grazing: Grazing and trailing permits would continue under current BLM and Forest Service rules.
Private Land: The NCA protects reasonable and feasible access to any private property that is located within or adjacent to the NCA. It would not impact county zoning designations.
Roads: The NCA would not impact county roads, their use or maintenance. The popular Dolores River Road, which travels along the river from the Dove Creek Pump Station, would not be affected. The bill states the road would not be improved beyond its existing primitive condition. No new or temporary roads would be constructed, and motorized vehicles must stay on designated routes, with exceptions for administrative or emergency purposes.
Wildfires: The NCA allows for control of wildfire, insects and disease.
Utilities: Right of ways, operations and maintenance would not be impacted by the NCA. New utility permits and right-of-ways would be allowed.
Ponderosa Gorge: The proposed NCA includes the popular Ponderosa Gorge, an 18-mile stretch of the river canyon popular with boaters.
The gorge will be managed in a manner that maintains its wilderness character. No new roads would be allowed, and motorized vehicles or equipment would be prohibited, with exceptions for public safety.
Commercial timber harvests in Ponderosa Gorge would be prohibited, with exceptions for ecological restoration.
Advisory Council: An 11-person Dolores River National Conservation Area Advisory Council would be created as part of the bill. The council would advise the Secretary of Interior on the preparation, implementation and monitoring of the management plan.
Two members will represent agricultural water user interests, and two will represent conservation interests. Two others will represent recreation interests, including one specifically for whitewater boating.
Dolores County, San Miguel County and the Ute Mountain Ute tribe each will have one representative. One member will be a grazing permit holder within the NCA, and another will be a private landowner that owns land in the immediate proximity to the NCA.
Council members must be residents of Dolores, San Miguel, Montezuma, Montrose or La Plata County. Terms will be for five years. Advisory meetings will be open to the public and be noticed.
Fish and wildlife leaders say they have their eye on potential closures of the Animas and San Juan rivers as well.
Devastating drought and disappearing runoff in far southwestern Colorado have prompted state officials to seek voluntary fishing restrictions on the Dolores River for the first time, and fish and wildlife leaders say they have their eye on potential closures of the Animas and San Juan rivers as well.
Intense rain over the weekend — generating eye-opening but perhaps deceptive coverage of flash floods and mudslides — are not nearly enough to bring Colorado’s Western Slope out of a 20-year drought that has drained rivers and desiccated pastures.
Conservation groups, meanwhile, say they are also worried about low river levels in more visible, main-stem branches of waterways usually popular with anglers and recreators in July, including the Colorado River…
Voluntary fishing closures on prime stretches of the Colorado are “imminent,” too, as soon as state weather warms up as expected in a few days, said Kendall Bakich, aquatic biologist for the Colorado Parks and Wildlife division in the Glenwood Springs area. Portions of the Colorado are seeing water temperatures above 70 degrees and related fish stress a month earlier than in a usual year, Bakich said.
Moreover, sediment from the heavy rains and mudslides that make some Front Range residents hear “drought relief” are actually making things harder on trout and other species, Bakich said. The murky water makes it harder for them to find food.
Even if you release a caught trout and it survives, Bakich said, this year’s far earlier than normal heat stresses are threatening the sperm and egg health in the species…
Bakich said she has worked the waters from Glenwood Springs upstream to State Bridge since 2007, and has not seen Colorado River temperatures rise this fast, this early…
Flow in the Dolores River is controlled almost completely by McPhee’s dam. Normally at this time of year, the stream is running at 60 to 80 cubic feet per second. Last week, it ran at 9 cfs, White said. Managers believe it will be down to 5 cfs later in the summer, barely a trickle in the wide stream bed.
So Parks and Wildlife is asking Dolores anglers to stop fishing by noon each day. Water comes out the bottom of McPhee at a chilly, trout-friendly 45 degrees, White said. In typical weather, anglers have a few miles of river to work below the dam before the water heats up to 75 degrees, a temperature band that starts weakening fish survival rates. Those 75-degree stretches have moved much closer to the dam this summer, he said.
The same is happening on the Animas and San Juan rivers in the southwest corner of the state, and voluntary closures are close on the horizon there, White said.
“We anticipate probably asking anglers to refrain from fishing at some point later in the summer if water temperatures start to get high, which we do anticipate this year,” he said.
The Colorado River sections could see some relief, from engineering if not from the weather.
Wildlife and conservation leaders said they are in talks with Front Range water diverters, who have rights to send Western Slope river water under the Continental Divide for urban and suburban household water, to release more flow west from their healthy reservoirs on the Colorado and its tributaries.
Where once a river ran, the Dolores River has all but disappeared in its lower reaches below McPhee Dam this summer, another causality of an intense drought that has gripped Southwest Colorado.
Striking images of dried up streambeds, tepid pools filled with suffocating algae and vegetation encroaching into the historic channel of the Dolores River has incited deep concerns over the ecological collapse of an entire waterway.
“It’s pretty devastating,” Jim White, an aquatic biologist for Colorado Parks and Wildlife, said. “It’s going to be a tough year for fish.”
Farmers and ranchers that rely on water from the reservoir, too, are also coming up on the losing end. This year, most irrigators are receiving just 5% to 10% of usual water shares, with valves expected to be shut off by the end of the month, an incredibly early end to the growing season sure to have economic fallouts.
“Absolutely, it’s the worst in the project history,” Ken Curtis, general manager of the Dolores Water Conservancy District, the agency that manages the dam, said of the situation on the Dolores River this year.
Completed in 1985, McPhee Dam bottlenecks the Dolores River in Southwest Colorado, just west of the town that bears its name. At the time, the project was sold as an insurance bank of water for both irrigators and the downstream fishery.
But in the years since, a crippling, 20-year drought has exposed intrinsic flaws within the management system put in place. And it all seems to have come to a head this summer after back-to-back poor water years, which has forced a reckoning among water users who rely on the strapped river…
Montezuma Tunnel entrance.
Montezuma Tunnel steel arches.
The Dolores River tumbles south out of the high country of the San Juan Mountains, and takes a sharp turn west near the town of Dolores before it heads more than 170 miles north to the Colorado River near Moab.
Near Dolores, the river skirts the edge of the Montezuma Valley, a different drainage basin where water is incredibly scarce. In the 1880s, Western settlers, looking to irrigate these arid fields, constructed a series of tunnels and large diversions to bring water over from the Dolores River.
This system, known as a transmountain diversion, brought a whole host of its own issues. Some years, flows were so erratic, that after spring runoff, agricultural needs reduced the Dolores River to a trickle. On top of concerns for the fishery below the dam, farmers and ranchers further out near Dove Creek also started to eye shares from the river. 4
So, by the mid-1900s, as was custom at the time, a dam was proposed. Much has been written and said about the concept of McPhee; even top-ranking Bureau of Reclamation officials have expressed on record the ill-advised nature of the water project in such an arid environment. Ranchers and farmers, however, came to hold water reserves in McPhee as an economic lifeline.
But, even a few years after completion, the dam started showing proverbially cracks in its plan after low-water years in the late 1980s…
“Deal with the devil”
McPhee’s first and foremost priority is to serve agriculture in the Montezuma Valley. Today, water out of the reservoir irrigates the fields of an estimated 1,500 farms, which range in size from small, three acre tracts to 1,000 acre operations.
Early on in the project’s management, however, low snowpack years in the mountains, which resulted in less available water supply coming into the dam, created tension among the competing interests for agricultural and the health of the river…
Ultimately, a “pool” of water was dedicated for releases out of the dam to support the fishery. But as the region increasingly dried out, shares have had to be reduced, and in some years the water sent down river has not provided enough habitat to sustain fish populations.
This summer, the fishery will receive just 5,000 acre feet of water, far below its 32,000 acre feet allotment. As a result, releases out of McPhee are expected to drop as low as 5 cubic feet per second, the lowest amount ever recorded (for reference, summer flows tend to be between 70 and 90 cfs).
Further downstream, the picture is even bleaker as water is lost to evaporation, sucked up by the soil and even in some cases used for irrigation. As of Wednesday, the stream gauge on the Dolores River at Bedrock, about 100 miles downstream of McPhee, was reading an inconceivable 0.45 cfs, virtually a nonexistent flow…
Short end of the stick
Thousands of fish are expected to die this year on the Dolores River.
For the first 10 miles or so downstream of McPhee Dam, the river boasts a robust trout fishery. Further on, as the river cuts toward the towns of Bedrock and Gateway, the waterway is home to many native fish, like the bluehead sucker and roundtail chub. Survival rates, as expected, are grim.
CPW’s White said that before the construction of the dam, spring runoff would replenish pools for fish to find refuge in. But that’s not the case in the post-dam world, and many fish will likely succumb to high water temperatures and the evaporation of pools in the hot summer months. And, conditions have set up perfectly for the invasive smallmouth bass to take over…
The Dolores River has been so changed and altered by the construction of McPhee Dam, and compounded by the effects of climate change, that it’s also prompted a multi-year study to understand the ecosystem’s new normal. Gigi Richard, director of the Four Corners Water Center at Fort Lewis College, said vegetation is now growing in the river bed, and the channel is losing the diversification of flow that support so many species…
Cutting off the tap
Explaining water rights is never an easy task for reporters with a word count.
But here we go: the Montezuma Valley Irrigation Co., formed in 1920 to consolidate the earliest water users, hold the most senior water rights. The next tiers in the pecking order are those served explicitly because of the construction of McPhee: farmers out near Dove Creek, the downstream fishery and the Ute Mountain Ute Tribe.
With McPhee receiving just a quarter of normal inflows from the Dolores this year, MVIC irrigators had their allocations slashed 50%, Curtis said. But that’s not the worst: all other users had their water supply cut to 5% to 10% from normal years, the worst project allocation in its history.
(The water supply for the towns of Cortez and Towaoc, which serves about 20,000 people, also comes from McPhee Reservoir and is expected to receive a sufficient amount this year.)…
Because of shortages, the Ute Mountain Ute Farm & Ranching Enterprise was forced to abandon most of its alfalfa, a profitable yet water-intensive crop, and focus on corn, less water dependent but also less valued…
All predictions show no signs of the drought in the Southwest reversing course, so what’s to become of a reservoir like McPhee that increasingly doesn’t have enough water to meet its own demands? It’s a question managers at Lake Powell and Lake Mead, which also face record low levels, also are grappling with.
Curtis, for his part, said the water district is consumed with the emergency-response nature of this year’s drought. Montezuma County earlier this month declared a disaster emergency because of the lack of water, and funds are being sought to offset losses for farmers.
This fall, Curtis expects more serious, long-term conversations about the future of McPhee. Even further on the horizon, the dam’s Operating Agreement plan between DWCD and the Bureau of Rec expires in 2025, expected to reinvigorate the conversation. Still, Curtis doesn’t foresee any fundamental changes in the way the reservoir provides water to its customers.
“It’s not going to be fun, I can tell you that,” he said. “Fundamentally, the project didn’t anticipate this amount of shortages, so we’re having to think about what the longer-term implications are. I’m not authorized to make those decisions, no single party really is.”
By the end of the year, McPhee Reservoir is expected to drop to its lowest level since construction, at about 40% capacity. Most of that remaining water, Curtis said, is inaccessible because of topography issues.
FromThe Cortez Journal (Jim Mimiaga) via The Durango Herald:
Irrigators tied to McPhee Reservoir contracts will receive just 5% to 10% of their normal supply, said Ken Curtis, general manager for the Dolores Water Conservancy District.
The shortages affect full-service users in the water district in Montezuma and Dolores counties, the Ute Mountain Ute Farm and Ranch and the downstream fishery.
The water district said no supplemental irrigation supplies will be available to the senior water-rights holders.
Alfalfa farmers are consolidating acreage to try to produce one small crop…
“Financial impacts will be hard on all agriculture producers,” said Dolores Water Conservancy District board president Bruce Smart, in a news release. “The recovery for producers, the Ute Mountain Tribe and the district will take years.”
The tribe’s Farm and Ranch Enterprise reports it will limit employment and cut back on buying farm supplies.
The 7,600-acre farm will only receive 10% of its normal water supply, tribal officials said.
The tribe will limit operations to growing corn for its Bow and Arrow Brand cornmeal mill, and to protect high-value alfalfa fields, said Ute Mountain Ute Tribal Chairman Manuel Heart…
The tribe intends to work closely with the Dolores Water Conservancy District and the U.S. Bureau of Reclamation to protect the continued viability of the Ute Farm and Ranch Enterprise.
Heart notes that the tribe’s participation in the Dolores Project is a result of the Colorado Ute Indian Water Rights Settlement Act. He said the tribe will exercise the settlement rights “in the fullest to protect our Farm and Ranch Enterprise.”
The economic impact of the irrigation water shortage will be widespread, as farmers expect a significant decrease in revenue that will trickle through the local economy, water officials said.
If next year’s supply doesn’t improve “multigenerational farm families may face bankruptcy,” said Curtis.
Unirrigated alfalfa fields will dominate the landscape this summer. Farmers noted that with some rain, the fallow fields can produce enough forage for cattle grazing. Ranchers have been contacting farmers to take advantage of the option, Deremo said.
Curtailed supply for Dove Creek
The town of Dove Creek depends on McPhee Reservoir water for its domestic water supply. The water is delivered via the Dove Creek Canal and into town reservoirs and a water treatment facility. But because of a shortened irrigation season, the canal will not run all summer, as it does during more normal water years.
The water district is working closely with Dove Creek officials to keep the town’s water reservoirs adequately stocked for the winter months, Curtis said.
During normal water years, the Dove Creek Canal runs to the first week in October, allowing Dove Creek to store 100 acre-feet that lasts them until May 1 the next year. This year, the canal is expected to shut off for irrigators before the end of June.
The other large irrigation supplier in the area, Montezuma Valley Irrigation Co., also faces shortages. Customers will receive only half their normal allocation. The irrigation company has the most senior water rights on the Dolores River, and therefore the impact of the water shortage is somewhat less…
Montezuma Valley Irrigation has storage rights in McPhee Reservoir, and owns Narraguinnep and Groundhog reservoirs.
Runoff low in Dolores River
Poor winter snowpack the past two years and no monsoonal rain for the past three years have hurt reservoir levels and depleted soil moisture.
The winter snowpack failed to deliver at historical average, peaking at only 83% of normal snowpack on April 1, then dropping to 25% after another dry, windy and warm spring. Recent rains and snowfall on the high peaks were helpful, but not enough to significantly improve water supply.
As dry conditions continue, 2021 is shaping up to be the fourth-lowest recorded runoff in the Dolores River, after 1977, 2002 and 2018.
Fish will suffer
As part of the McPhee Reservoir project, the downstream fishery is allocated 32,000 acre-feet of water during normal water years for timed releases downstream to benefit sport and native fish.
This year, the fish pool will receive 5,000 acre-feet of its normal allocation.
The Dolores River below McPhee dam will see flows of 10 cubic feet per second for a few months, then it will drop to a trickle of 5 cfs for eight months until spring.
The river below the dam faces significant trout and native fish population losses, said Jim White, aquatic biologist for Colorado Parks and Wildlife…
Flannel mouth sucker
Blue head sucker
The low flows will also affect native fish in the lower reaches of the Dolores River – the flannelmouth sucker, the bluehead sucker and the roundtail chub. The fish, listed by CPW as species of concern, have adapted to warm water, but they still need pools and flowing water to survive.
Farmers expected to receive just a fraction of normal supply
Runoff from below-average snowpack is forecast to result in the lowest project irrigation supply in McPhee Reservoir history.
According to most probable forecast, Dolores River Basin snowmelt is expected to deliver 95,000 acre-feet of water to McPhee Reservoir, just 32% of the average 295,000 acre-feet average, reports the Colorado River Basin Forecast Center. The forecast could also continue to drop.
Full-service farmers of the Dolores Project are expected to receive just 1 inch per acre of irrigation water, or 4.5% of the 22 inches per acre provided when the reservoir fills, reports Ken Curtis, general manager for the Dolores Water Conservancy District that manages McPhee.
The forecast of 1 inch per acre is “the wost ever” for the Dolores Project, he said. The reservoir first filled in the late 1980s.
The previous worst irrigation seasons for McPhee Reservoir were in 2013 and 2002, when farmers received 6 inches per acre.
The amount of water predicted for this year is not enough for even one normal crop of alfalfa. With a full supply farmers typically get three to four crops of alfalfa per year. Farmers will be forced to consolidate crops into smaller acreage to produce anything on the limited water.
This year’s forecast shows McPhee Reservoir will fill less than 40% of its 229,000 acre-feet active capacity, according to forecast models. The reservoir had no significant carryover supply from last year’s water season.
Water shortages are across the board, except for domestic supplies for municipalities.
Ute Farm and Ranch on the Ute Mountain Ute Reservation is predicted to receive about 2,000 acre-feet, or 8.5% of the 23,300 acre-feet delivered when the reservoir has a full supply.
The water supply for downstream fish habitat dropped to less than 5,000 acre-feet of the 32,000 acre-feet provided when the reservoir fills.
Ashley Nielson, a senior hydrologist with the Colorado River Basin Forecast Center, said snowpack in the Dolores Basin took hits from multiple angles.
With the exception of a few good snowstorms, the basin experienced an extended dry period since April 2020, she said.
No monsoonal precipitation last summer dried out soils, which will cause snowmelt to be absorbed into the ground before it hits the river and McPhee.
Below-normal snowpack further suffered from warm weather and high winds in April, plus dust on snow that sped up evaporation.
April precipitation at the Lizard Head Pass Snotel is below normal, showing 0.2 inches, or 15% of the average 1.4 inches for the month…
On March 29, the Dolores Basin snowpack showed 83% of average for snow-water equivalent. On April 19, snowpack water equivalent had dropped to 32%.
Below-average snowpack and ongoing drought will hurt flows and fish habitat below McPhee Dam going into spring and summer, reports Colorado Parks and Wildlife.
Water releases from the dam are expected to be under 15 cubic feet per second and could possibly drop as low as 3 cfs, said Jim White, a CPW aquatic biologist, in a April 14 news release.
During normal snowpack years, McPhee Reservoir fills, and the allocated fish pool allows for a sustained dam release of 60 cfs in summer.
Fish flows increase if snowpack runoff exceeds reservoir capacity, which prompts a recreational boating release. But a recreational water release will not happen this year because of below average snowpack and low reservoir carryover from last water season.
As of April 13, Snotels in the Dolores Basin reported 39% of average snowpack for snow water equivalent.
Trout and native fish will be adversely impacted by the water shortage below the dam, White said.
The 12-mile section of river that flows through the Lone Dome State Wildlife Area from below the dam to Bradfield Bridge is a popular tail-water fishery. Most trout fishing is done within the first 6 miles.
White said the lower flows will shrink the river habitat, and many brown and rainbow trout likely will die. The water coming out of the dam is about 42 degrees Fahrenheit, which is an ideal temperature for trout. But with such a low flow the water will warm quickly as it moves downstream…
The low flows will also affect native fish that live in the lower reaches of the Dolores River ─ the flannelmouth sucker, the bluehead sucker and the roundtail chub. The fish, listed by CPW as species of concern, have adapted to warm water, but they still need pools and flowing water to survive.
White is concerned about lower sections of the river drying up or being connected by only tiny rivulets of water.
Making the problem worse is the smallmouth bass, an invasive non-native fish that thrives in the lower Dolores River but preys on young native fish. Anglers are encouraged to fish for smallmouth bass; they are abundant, fairly easy to catch, tasty and have no bag or possession limit.
As drought continues to grip the West, more and more rivers will face the same scenario — this year and beyond.
“All of this is a result of three things: low snowpack, dry soil that will absorb runoff and no carryover water in the reservoir from last year,” White said.
FromThe Cortez Journal (Jim Mimiaga) via The Durango Herald:
Sorry skiers, ranchers and kayakers: Weather observers see no relief in sight for a persistent drought that has gripped the Four Corners.
A strong La Niña weather pattern has helped shift the jet stream farther north, which keeps storms from reaching the Four Corners, officials said.
“It’s the strongest La Niña in 10 years,” said Jim Andrus, a weather observer for the National Weather Service. “Even when we do get storms that dip down our way, they are weak at most.”
The long-term forecast for the Four Corners is below-normal precipitation and above-normal temperatures, said Norv Larson, a meteorologist with the National Weather Service.
High pressure and a dry air mass are generally blocking storms from reaching and forming in the area, he said…
Snowpack is well below average in Southwest Colorado.
Snotel stations in the mountains that measure snowfall, show the Dolores and San Miguel river basins are 48% of normal as of Dec. 7.
The Animas River Basin is at 38% of normal, and the Gunnison River Basin is at 53% of normal.
The Telluride Ski Resort reports a 21-inch base, and Purgatory Resort has a 16-inch base.
As of Dec. 3, Southwest Colorado and most of the Western Slope were in “exceptional” drought, the worst level out of five, according to the U.S. Drought Monitor. Most of Utah and Arizona also were in exceptional drought.

When Water Justice is Absent, Communities Speak Up
Two years ago, a company that analyzes property data crunched the numbers on more than 8,600 zip codes in the United States and found that America’s most polluted neighborhood was in northeast Denver. The study, from ATTOM Data Solutions, shows that Denver’s 80216 zip code, which includes Globeville, Elyria-Swansea and River North, topped its “environmental hazard index.” As of 2017, the U.S. Environmental Protection Agency’s Toxic Release Inventory reported that 22 facilities were still releasing toxic chemicals in 80216, chemicals such as nickel, lead, methanol, creosote and more.
“The neighborhood is parked between gas refineries, the former airport, and then, also, what was at one time an Army base making mustard gas,” says University of Denver law professor Tom Romero, II, who has spent his career dissecting the factors behind environmental injustices in Colorado. There are two Superfund sites and six brownfield sites in 80216, plus the knot of Interstate 70 and Interstate 25 severs the neighborhood from the rest of Denver and increases pollution from highway traffic. The area is also home to a predominantly low-income, Hispanic and Latinx community, says Candi CdeBaca, Denver City Councilwoman for northeast Denver’s District 9.
Last year, CdeBaca became the first person from the neighborhoods to represent on the Denver City Council, ever. She points to an opposition campaign to the Central 70 Project as the beginning of the neighborhood rallying to achieve representation against environmental inequities.
The Central 70 Project broke ground in 2018 to widen the highway through Denver. It will demolish the viaduct that carries I-70 over Elyria-Swansea, replacing it with a below-grade highway. Residents had a list of worries: losing their homes to eminent domain, living even closer to the highway, and unearthing a Superfund site, which they feared would re-expose harmful heavy metals and increase health risks, CdeBaca says.
Their opposition campaign didn’t stop the highway work, but the community came together and won in one sense—the Colorado Department of Transportation will pay for a long-term health study, collecting data to determine whether toxins in the air, soil and water are making residents sick. They also gained a louder voice. “Those losses were the first start of me galvanizing some community power around environmental racism,” says CdeBaca. “Now we have this amplification of groups who never had representation in our government from the neighborhoods that were polluted.” She points to the importance of local voice and representation in all issues, particularly for communities that want to bring about environmental justice. “There is nothing that I support more than activating people power,” CdeBaca says.
With water affordability, access and quality challenges—all of which can translate into health impacts—the role of water in Colorado isn’t always one of fostering healthy communities, yet it could and should be. What contributes to these less-than-whole communities? And what does it take to recognize the issues and how they evolved, address power imbalances, engage the community, and restore equity where it’s been missing?
What is Environmental Justice?
Environmental injustices in Colorado, or anywhere, can span cities and suburbs, sovereign tribal lands, and rural communities. They have their roots in narratives of immigration, development and industry, and political power dynamics, further influenced by evolving legal and regulatory frameworks.
In 1990, EPA Administrator William Reilly created an Environmental Equity Workgroup to assess evidence that “racial minority and low-income communities bear a higher environmental risk burden than the general population.” The agency, which went on to establish an Environmental Equity office in 1992, later changing its name to the Office of Environmental Justice in 1994, defines environmental justice as the “fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income, with respect to the development, implementation and enforcement of environmental laws, regulations and policies.” It has since expanded to offer a range of programs that provide services from grant funding to technical assistance and training. It also runs a National Environmental Justice Hotline.
Another early definition of environmental justice came from University of Michigan professor Bunyan Bryant, who said it refers to places “where people can interact with confidence that the environment is safe, nurturing and productive. Environmental justice is served when people can realize their highest potential.”
Scholars add additional layers to the term—it’s not just about identifying who is or isn’t harmed but includes some form of restitution, says Kelsea MacIlroy, an adjunct professor and PhD candidate in the sociology department at Colorado State University.
“There are a lot of different ways to talk about justice that aren’t just about who and how but also about a long-term social justice component,” MacIlroy says. “Does the community actually have an authentic seat at the table in addressing the ills?”
80216 may feel it all. “Denver was segregated, and that segregation manifested itself in a variety of ways in terms of water,” Romero says. “It meant that Denver’s communities of color, particularly African Americans and Mexican Americans, were living in close proximity to the areas with heavy industry, where the affordable housing is.” That’s a pattern and practice, he says, that was established in the 20th century and continues today. Many environmental justice cases have similar roots, as repeated practices that ultimately create winners and losers.
When Government Fails
Americans watched one of the most high-profile environmental justice cases unfold in Flint, Michigan, in 2015 and 2016 when corroded lead pipes poisoned the population.
To save money, in April 2014, the city switched its drinking water source and began supplying residents with Flint River water that wasn’t treated under federal anti-corrosion rules. The population was predominantly black, and more than 40 percent of residents were below the poverty threshold. According to the National Institute of Environmental Health Sciences, no level of lead exposure is safe but higher lead exposure leads to more health challenges including anemia, kidney and brain damage, heart disease, decreased IQ and more. In children, the impacts are especially toxic.
Residents began noticing a rusty tint to their tap water in the summer of 2015, but it wasn’t until October 2015 that the governor ordered Flint’s water source switched. By then, though the new water was safe, the plumbing wasn’t—corroded pipes continued to leach lead into drinking water. Bottled water and free faucet filters to remove lead at the point of use were distributed.
More than five years after the crisis in Flint began, the city and its residents are still recovering. The city’s FAST Start program is removing and replacing lead and galvanized steel service lines across the city, but it’s a big, expensive job. FAST Start has been funded with $25 million from the State of Michigan and $100 million allocated by Congress through the Federal Water Infrastructure Improvement for the Nation Act of 2016. As of December 2019, less than 40 percent of the city’s pipes had been replaced, with many residents still relying on faucet filters or bottled water.
Fifteen state and local officials were charged with various crimes, including involuntary manslaughter—some took plea deals and most cases were dropped. Residents now mistrust their water and water providers. That mistrust has flooded the nation, with many more communities now coping with elevated lead levels and lead pipe replacement.
According to the independent Flint Water Advisory Task Force’s final report, released in 2016, breakdowns in protocol, dismissal of problems, and failure to protect people occurred at nearly every level of government. Not only were customers supplied with unsafe drinking water, government officials were slow to acknowledge the problems and rectify the issue by providing safe water. According to the 2016 report, the Flint water crisis is a “story of government failure, intransigence, unpreparedness, delay, inaction, and environmental justice.” Had there been local control of resources and decisions, they write, the problems wouldn’t have occurred in the first place.
Coping with Forever Chemicals
Flint’s toxic water is not unlike the water quality issues discovered in 2016 in the Colorado towns of Fountain and Security-Widefield. That’s when water providers and residents learned that PFAS chemicals, short for per- and poly-fluoroalkyl substances, were detected at levels above EPA’s new 2016 health advisory levels. The source of the chemicals: firefighting foam used for decades to extinguish training fuel fires at the U.S. Air Force’s Peterson Air Force Base. The Air Force now uses a replacement foam at the base, and in 2019, the Colorado Legislature enacted restrictions and bans on PFAS foam, but the damage has been done. PFAS are known as “forever chemicals” because they bioaccumulate and remain in the environment for a long time, with half lives (the amount of time it takes the chemical to decrease to half its original value) in humans of two to eight years, depending on the chemical. They have been linked to cancers, liver and kidney damage, high cholesterol, low infant birth weight, and other ailments.
“We ended up having 16 family members that lived within that area that had cancer, and five of them died of kidney cancer,” said Mark Favors, during a public event on PFAS at Colorado School of Mines in January 2020. Favors is a former resident of Security, a U.S. Army veteran, a PFAS activist, and member of the Fountain Valley Clean Water Coalition. “A lot of [my family] are military veterans. One of my cousins, while he was doing two combat tours in Iraq, the Air Force was contaminating their drinking water. That’s the crazy part. How they’ve admitted it and it’s just hard to get any type of justice on the issue,” Favors says.
These southern El Paso County towns aren’t home to what are often considered disadvantaged populations—the poverty rate is between 8 and 9 percent, slightly less than the statewide average; about 60 percent of residents are white, and about 20 percent are Hispanic or Latinx, according to the 2017 U.S. Census. However, census numbers don’t represent military personnel who temporarily reside in the area. According to El Paso County’s Health Indicators report, published in 2012, four military bases in the county employ 40,500 military personnel and about 21,000 contract personnel.
When EPA tightened its health advisory levels in 2016, they were 10 times more restrictive than what the agency had previously advised, and water providers realized they had a problem. They acted quickly to provide residents with free bottled water and water filling stations while they suspended use of the aquifer, then worked to broker deals to purchase clean water from other municipalities. Some of those deals were only temporary. Since June 2018, the City of Fountain has worked to get back on its groundwater supply, treating the groundwater with granular activated carbon units provided by the Air Force. Now it is working with the U.S. Army Corps of Engineers to construct a full, permanent groundwater treatment plant. The story in Security is similar—the Security Water and Sanitation District has been importing water, primarily from Pueblo Reservoir, to meet the needs of its residents since 2016, which involved building new pipelines and purchasing extra water from Colorado Springs Utilities—an added cost. Security avoided raising water rates for a time, paying those costs out of its cash reserves. By 2018, residents had to absorb a 15 percent rate increase, with another 9.5 percent increase in 2019.
The Army Corps of Engineers is constructing a treatment facility in Security, too, which should be complete by the end of 2020. Once the plant is finished, Security will switch back to a combination of groundwater and surface water, and rates should stabilize once the costs of those pipelines are recovered, says Roy Heald, general manager at Security Water and Sanitation Districts.
Who pays to protect the health of those who rely on this water? “What responsibility did [the Air Force] have in rectifying this? What about the local sanitation districts? They have to deal with this. It’s not their fault but they’re tasked with giving clean water,” says MacIlroy at Colorado State University.
“The Air Force really has stepped up,” Heald says. But they may have to step up further—in 2019, the Security Water and Sanitation Districts and the Pikes Peak Community Foundation, another affected entity, sued the Air Force to recoup the costs of purchasing and piping in clean water. Their lawsuit cites negligence for disposal of chemicals, remediation of contamination, and breaching a responsibility to prevent dangerous conditions on the defendant’s property. Heald wouldn’t comment on the pending lawsuit, but says, “As long as [cash] reserves are at an adequate level, if we received a windfall there would be no place else for it to go besides back to our customers.” Those recouped costs would likely take the form of lower or stabilized rates.
Residents are also pushing for justice through a class-action lawsuit brought by the Colorado Springs-based McDivitt Lawfirm, which has teamed up with a personal injury law firm in New York to file against 3M, Tyco Fire Products, and other manufacturers of the firefighting foam.
“There’s going to have to be some sort of accountability and justice for these people who unknowingly, for years, drank colorless, odorless high amounts of PFAS,” says Favors. He calls for better oversight and demands that polluters are held accountable.
As for coping with PFAS-related health challenges, there are still a lot of unknowns, but El Paso County was selected to participate in two national Centers for Disease Control and Prevention studies to better assess the dangers of human exposure to PFAS, and to evaluate exposure pathways.
Locally, the study and lawsuits might help recoup some financial damages—but PFAS-related water contamination isn’t isolated to these Colorado communities. In July 2019, the Environmental Working Group mapped at least 712 documented cases of PFAS contamination across 49 states. Lawmakers in the U.S. House of Representatives, hoping to implement a national PFAS drinking water standard, estimate the number is even higher: 1,400 communities suffer from PFAS contamination. A U.S. Senate version of a PFAS-regulating bill has yet to be introduced. But in February, EPA released a draft proposal to consider regulating PFOS and PFOA, just two of the thousands of PFAS.
Justice through Water Rights
Environmental justice isn’t exclusively an urban issue. Injustices involving pollution, public health, access, affordability and water can be wrought anyplace—including rural and suburban areas. For rural communities, the issue comes to a head when people, organizations or entities in power seek more water for their needs at the cost of others.
In southern Colorado’s San Luis Valley, acequia communities fought for years to protect their water rights and way of life. Acequias are an equity-based irrigation system introduced by the original Spanish and Mexican settlers of southern Colorado. “What it means is that the entire community is only benefitted when all resources are shared,” says Judy Lopez, conservation project manager with Colorado Open Lands. There, Lopez works with landowners to preserve wildlife habitat, forests, culturally significant lands, and ag lands—including those served by acequias.
The Town of San Luis, the heart of Colorado’s acequia community, is one of the most economically disadvantaged in the state. It’s in Costilla County, where more than 60 percent of the population is Hispanic or Latinx—more than any other county in Colorado—and 25 percent of the population live in poverty, according to the 2017 U.S. Census. But the people there are long-time landowners, never separated from the land their ancestors settled, four to seven generations back, Lopez says. They have the state’s original water rights to match, including Colorado’s oldest continuously operated water right, the San Luis People’s Ditch, an acequia established in 1852.
Prior to statehood, the territorial government recognized acequia water rights. But when the Colorado Constitution established the right of prior appropriation, the priority scheme of “first in time, first in right” became the law, challenging communal rights.
“It was very difficult for [acequias] to go to water court and say, ‘This guy is taking my water,’” Lopez says. “It was very difficult to quantify the use and who was using it.”
It wasn’t until 2009 that the Colorado Legislature passed the Acequia Recognition Law. The law was developed by Rep. Ed Vigil with the help of the Sangre de Cristo Acequia Association, an entity that represents more than 73 acequias and 300 families who depend on them. Amended in 2013, the law solidifies the rights of acequia users. According to the Colorado Acequia Handbook, it allows “acequias to continue to exercise their traditional roles in governing community access to water, and also strengthens their ability to protect their water.”
In order to be recognized under the Acequia Recognition Act, acequias needed bylaws. Over the past six years, Colorado Open Lands, the Sangre de Cristo Acequia Association, and the University of Colorado Boulder have partnered to help 42 acequias write bylaws, thereby protecting their water. “The bylaws were still based, in large part, on those oral traditions,” Lopez says, “and included protective language that said, ‘If a water right is sold, or a piece of land is sold, that acequia gets the first right to purchase those rights.’”
Even having water rights doesn’t guarantee water access: Over the past few decades, the federal government has settled longstanding water rights cases with sovereign tribes, in many cases backdating tribal water rights to the dates of their reservations’ establishment. Although the tribes now have the nation’s oldest established water rights, they haven’t always, and they still come up against structural and financial barriers that prevent them from developing water and getting the real benefit of those rights.
Of the more than 570 federally recognized tribes in the United States, as of 2019 only 36 tribal water rights settlements had been federally approved. The Ute Mountain Ute and Southern Ute tribes in Colorado are among that small number, but despite their long journey, the tribes still don’t have access to all the water they own.
Tribal water rights have their roots in the Winters Doctrine, a 1908 case which established tribal water rights based on the date the federal government created their reservations—thereby moving tribal water rights to “first in line” among users.
In the 1970s and ‘80s, the U.S. government filed and worked through claims on behalf of the Ute Mountain Ute and Southern Ute tribes to surface waters in southwestern Colorado. In the 1980s, Congress approved a settlement between the tribes, the federal government and other parties; in 2000, the Colorado Ute Indian Water Rights Settlement Act was amended, entitling tribes to water from the U.S. Bureau of Reclamation’s proposed Animas-La Plata Project (A-LP), as well as from the Dolores Project’s McPhee Reservoir. Construction on A-LP began in 2001, and the project’s key feature, Lake Nighthorse—named for Sen. Ben Nighthorse Campbell—began filling in 2009.
Prior to the Dolores Project, many people living in Towaoc, on the Ute Mountain Ute Reservation, did not have running water and instead trucked it in to fill water tanks at their homes, says Ernest House, Jr., senior policy director with the Keystone Policy Center and former director of the Colorado Commission of Indian Affairs. His late father, Ernest House, Sr., was pivotal in that fight for water. “I was fortunate, my father was able to see A-LP completed. I think he probably, in his own right, couldn’t believe that it would have been done and could be done,” he says. But even today, some Southern Ute and Ute Mountain Ute communities still lack access to water, and aging infrastructure from the 1980s needs updating and repairs.
“Our tribes as sovereign nations cannot maintain or move forward without access to water,” House says. “We have to remind people that we have tribal nations in Colorado, and that we have other tribes that continue to call Colorado home, that were removed from the state, either by treaty or forced removal,” he says, adding that acknowledging the difficult past must be a part of conversations about the future.
Those conversations include state, regional, and federal-level water planning. The Colorado tribes are engaged in Colorado’s basin roundtable process, with both tribes occupying seats on the Southwest Basin Roundtable, says Greg Johnson, who heads the Colorado Water Conservation Board’s Water Supply Planning Section (and serves on the Water Education Colorado Board of Trustees). Through the roundtables, local stakeholders conduct basin-wide water planning that is eventually integrated into the statewide Colorado Water Plan. However, until recently, tribal involvement in regional Colorado River negotiations between the seven U.S. basin states and federal government has been nonexistent. Change is brewing—a 2018 federal Tribal Water Study highlighted how tribal water resources could impact Colorado River operations, while a new Water and Tribes Initiative is working to build tribal capacity and participation in water negotiations throughout the basin.
“The Utes have been in what we call Colorado for the last 10,000 to 12,000 years,” House says. “It would be a shame if we were left out of the conversations [about water].”
The External Costs of Industry
Government is vital to addressing the legacy of environmental injustice, and preventing future problems, but finding solutions also demands reconsidering how business is done.
Consider Colorado’s relationship with the extraction industry, visible in the 19th-century mines that pock mountain towns, uranium-rich communities like Nulca, and the escalation of oil and gas drilling today. Colorado is an “epicenter” of extraction and environmental justice issues, says Stephanie Malin, associate professor at Colorado State University and a sociologist who studies energy development and extraction.
Lack of local control in the past has been especially frustrating, Malin says, since private corporations earn profits off the resources but then outsource the impacts. In the end, extractive industries have a track record of leaving communities and governments to bear the costs of cleanup.
Take Gold King Mine as one high-profile example. In August 2015, wastewater from an abandoned mine in San Juan County contaminated the Animas River between Silverton and Durango. Contractors hired by EPA accidentally caused 3 million gallons of mine waste, laden with heavy metals, to wash into the Animas. New Mexico, Utah, and the Navajo Nation all filed to sue EPA, with farmers reporting that they couldn’t water their crops and others saying they had to truck in alternative water supplies. But those responsible for the contamination were long-gone. Like tens of thousands of other mines in the region, the Gold King Mine was abandoned in the early 20th century.
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)—more commonly called Superfund—which Congress passed in 1980, was originally set up as a “polluter tax” on oil, gas and chemical companies at risk of contaminating communities or the environment. But Congress never reauthorized the tax, which expired in 1995. By the early 21st century, the fund was bankrupt. Today, these cleanups are funded entirely by taxpayers.
“It’s part of a bigger pattern of privatizing profit and nationalizing, or socializing, risk,” Malin says. “Then, communities and the environment are left holding the ‘external’ costs.” Those external costs, she says, are nearly unquantifiable: “The intergenerational impacts in particular are so hard to gauge, in terms of what the communities are absorbing.”
While these problems can seem intractable, there are solutions, Malin says. For example, the bond amounts companies are required to pay up-front should better reflect the actual cost of cleanup, she says. Last year, Colorado lawmakers made strides to unburden taxpayers in just that way, with an update to Colorado’s old mining law.
The new Colorado law, HB19-1113, makes sure water quality impacts from mining are accounted for and long-term impacts are avoided. The law says that the industry can no longer self bond—a practice that allowed mine operators to demonstrate they had the financial resources to cover clean-up costs rather than providing the resources up front. Without self bonding, taxpayers won’t be left paying for remediation if the company goes bankrupt. It also requires mine operators to factor water quality protection costs into their bond—and requires most to develop a water quality treatment plan. This means that reclamation plans must include a reasonable end date for any needed water quality treatment, hopefully ensuring Colorado will avoid new perpetually polluting mines.
State lawmakers are currently looking at a more encompassing environmental justice bill, HB20-1143, introduced in January 2020. At press time the bill was still under consideration. If it moves forward as introduced, the bill would increase the maximum civil fine for air and water quality violations—from $10,000 per day to $47,357 per day, which would be adjusted annually according to the consumer price index—reallocating some of the financial burden back on polluters. It would also authorize the use of the money in the state’s water quality improvement fund, which is where those water quality violation fines go, to pay for projects addressing impacts to communities. The bill would also bolster the state’s environmental justice efforts, with a new environmental justice advisory board and environmental justice ombudsperson who would run the advisory board and advocate for environmental justice communities.
Speaking up for Tomorrow’s Climate
Environmental justice can’t be about a single issue, says Lizeth Chacón, executive director of the Colorado People’s Alliance, a racial-justice, member-led organization based in Denver and Pueblo. That means looking at water-focused environmental justice alongside related issues such as climate change, racial justice, inequities, poverty, housing, power dynamics, and more.
“When we are talking to our members, we are talking to them about the fact that they are working two jobs and still cannot put dinner on the table in the week, talking that they live in fear of being deported and being separated from their families, talking about the fact that they are sick, or have headaches, or have to spend money on water because they can’t drink the water coming out of their tap like other people can,” she says. “It can’t be seen as one issue … This work has to be holistic.”
Currently, the Colorado People’s Alliance is working on a climate campaign directed by its members in Commerce City. “They said, ‘This is something that’s impacting all of us, regardless of where we’re from, whether we’re undocumented or documented, what our economic status is,’” she says. The Alliance is focused on greenhouse gas emissions, which have immediate health impacts and long-term water effects.
Another approach in northeast Denver is proceeding thanks to an EPA environmental justice grant, in which organizers will convene youth, local leaders, and scientists to create a community science project that leads to a more fishable and swimmable Denver South Platte River. The river flows through Elyria-Swansea and Globeville, but it used to be a dumping ground, with a landfill beside its banks. Clean ups and improved recreational access, much of which has been spearheaded by the nonprofit Greenway Foundation since its founding in 1974, have created opportunities for kayakers downtown, but river access in northeast Denver, beyond the popular Confluence Park, is limited. In addition, E. Coli levels are often high, making swimming inadvisable. Access to a healthy waterway makes communities more vibrant and whole, supporting health, wellbeing, recreation, and cultural and spiritual practices, but also connection. This may be the only recreational water access available to some urbanites.
“Rivers are one of the major pathways to healing the environment and healing ourselves,” said Jorge Figueroa at an initial workshop for this project in December 2019, where they began to establish a youth advisory board. Figueroa runs El Laboratorio, an organization that brings people together from different disciplines and cultures to creatively solve environmental challenges. (He is also on the Water Education Colorado Board of Trustees.) He’s working on this project with Lincoln Hills Cares, a nonprofit that provides outdoor education, recreation and experiences to youth who may not otherwise have these opportunities; and Colorado State University, which is developing a new campus at the National Western Center, called Spur, in the neighborhood. The partners expect to have a plan ready by the end of 2020, and the project should begin in 2021.
Figueroa, who grew up and has family in Puerto Rico, also witnessed, up close, the wave of climate refugees who left his home state after Hurricane Maria devastated it in 2017.
“It’s critical for us to invest in climate-resilient infrastructure and in the reliability of our municipal potable water systems,” Figueroa says. “But from an equity perspective, we need to ensure that the more than a trillion dollars that will be invested in the nation’s public water systems provide the most benefit to the most people.” His suggestion to build climate resiliency in an equitable way: water conservation. “Water conservation can be a supreme water equity tool: It provides cheaper water for the community and more resiliency and reliability for the system. It’s not only an ideal climate change adaptation strategy but also is one of the top, by far, equity water strategies.” When you don’t consider equity in water decisions, you can make vulnerable communities more vulnerable, he says.
Whether working to improve environmental justice structurally and physically through conservation and resiliencies, or politically and financially through new regulations, bonding or taxation, there are many opportunities to do better. But there are also social justice elements to work on. Chacón recommends involving community members at the beginning of a process—not at the end. She says it’s important to listen—and to not dismiss people when they disagree.
Looking forward, it’s up to everyone in positions of power to actively create space for disadvantaged communities to lead, says Chacón. “To us, the people who are closest to the pain are the ones closest to the solution because they know what’s happening in their community best of anyone.”
Some of the principles of engaging communities in these situations are “almost universal,” says Colorado’s Michael Wenstrom, an environmental protection specialist in EPA’s Environmental Justice Program. Wenstrom worked in Flint over the course of a year following the water emergency, “assisting them to connect with processes, in understanding what their rights are, and helping them learn how to raise their voices effectively,” he says.
He says that where communities and families are already overburdened—with poverty, crime, racism—they often don’t have time, expertise or resources to recognize the problems, nevermind address them. “In addition, people in low-income communities may be less inclined to raise their voices for various reasons,” Wenstrom says. Reasons could include racism, job discrimination, or, for some, the fear of being identified as an illegal resident.
He says officials like him who come into communities as outsiders must be careful, persistent, and work to build trust. “As trust builds, we can then start pointing people toward tackling issues related to pollution or public health,” he says. But, Wenstrom cautions, if people don’t believe they can make a difference, they won’t raise their voices in the first place.

Longtime district engineer Ken Curtis has been appointed the new general manager for the Dolores Water Conservancy District.
Curtis replaces Mike Preston, who is retiring after leading the organization that manages McPhee Reservoir for the past 12 years. Preston will stay on during a transitional period serving in external relations.
The two have worked closely together as a management team, said DWCD board president Bruce Smart.
Curtis served as chief of engineering and construction during the 12 years that Preston was general manager…
Preston informed the board in February his intention to retire, and recommended Curtis as his successor. The board agreed to the transition plan in order to facilitate a smooth change over…
Curtis has been involved in all aspects of water management, including delivering water to customers, oversight of project maintenance and upgrades, and invasive mussel prevention program. He also monitors reservoir levels and Dolores River inflows, conducts water policy research and community outreach, and helps coordinate the downstream fishery release and whitewater boating spill.
Coming out of extreme drought, water releases a pleasant surprise
For 51 days this spring and summer, water managers opened the spigots on McPhee Reservoir, sending millions of gallons of water down the Dolores River – a boon to fish, farmers and boaters.
During the last 20 years, only 10 years have been boatable. But this year was remarkable for the number of boating days after extreme drought conditions in 2018.
McPhee Reservoir started 2019 with one of the poorest water levels in its history, but extraordinary snowfall allowed the Dolores Water Conservancy District to fill the reservoir and release 135,000 acre-feet of water.
The high-flow days will benefit the ecology of the entire corridor, said Mike Preston, general manager of the district. The big releases occurred between Memorial Day weekend and the first week of July, with a short intermission after Memorial Day.
The district met with stakeholders, such as boaters and biologists, weekly to determine water management strategy, Preston said.
“So far, everybody is pretty happy,” he said.
The Dolores River Boating Advocates were pleased with the number of boating days. While it was not the longest season ever, it was a good run, said Sam Carter, program and outreach coordinator for the group…
The high levels in the reservoir will allow the district to provide irrigators all the water they have rights to and hold over water in the reservoir for next season, Preston said. The releases from the reservoir will also have lasting benefits for native fish and trees along the river, experts said.
The high flows help maintain and improve habitat for three species of native fish: roundtail chub, bluehead sucker and flannelmouth sucker, said Jim White, aquatic biologist for Colorado Parks and Wildlife.
The bluehead and flannelmouth sucker populations are both depressed in the Dolores. Their populations have been hurt by non-native fish and changes in habitat because of the dam, he said…
This summer, White said he may have observed benefits of the last big water year on the Dolores, which was in 2017. He was surveying fish in Slick Rock Canyon and found an abundance of young flannelmouth suckers possibly from 2017 or 2018, he said. Higher water helps support spawning…
The large amount of spring runoff released from McPhee also kept the water district from needing to tap into water set aside specifically for fish, Preston said. So now the same amount of water can be released over a shorter period of time, which will be beneficial for fish.
The high-water year will also have lasting benefits for trees, such as cottonwoods and willows, because it will recharge the groundwater in the floodplain, said Cynthia Dott, a biology professor at Fort Lewis College. Dott specializes in studying the floodplain forest habitat and has worked on the Dolores River with her students.
Rainwater does not provide enough water to recharge the water table, and when the table drops too low, it can hurt large cottonwoods, she said. But there should be plenty of groundwater for the trees to tap into next year, she said.
“They will have plenty of water to keep their feet wet,” she said.
The high flows were also traditionally needed to scour the banks of rivers and leave open, muddy areas for young cottonwood seedlings to get established, she said.
However, because there have been so many years of low flows on the Dolores, willows have established themselves along the banks and high flows now are not enough to rip them free, she said.
“You’re all here at a momentous time,” guide Trey Roberts said before the drop. “You’re about to raft a big, famous, rare river.”
Jeanette Healy of Utah had been waiting 10-plus years for this chance on the Dolores. Doug Nie, a kayaker from Albuquerque, had been waiting even longer. Also here were Rick and Beverly Anderson, a young couple from Albuquerque as well.
“We figured we could do the Las Animas and Arkansas out in (Buena Vista) any year,” Rick said. “But this is our one chance to do Dolores.”
Chances have been tough to come by since the 1980s, when the McPhee Dam began trapping the water that Dominguez and Escalante found to be rushing during their 1776 expedition. El Rio de Nuestra Señora de Dolores, they called it — the River of Our Lady of Sorrows…
Most joyful now are the boaters who had hoped this year’s snowpack would grant McPhee’s occasional controlled “spills.” As of last week, the Dolores Water Conservancy District expected releases to remain at or above 1,200 cubic feet per second through June 23, keeping the river fun until then at least.
That would mean a rafting season of almost one month here, which seems a short window. But longtime river rats regret to say that’s long for the Dolores.
Bill Dvorak, who’s frequented the state’s rivers since the ’60s, can’t recall a longer season. He ran the Dolores in 2017; his last time before that was 2009. “Every six to eight years is about when I get on it,” he said.
And he gets on it almost every floatable opportunity. The Dolores, after all, is easily his favorite river in Colorado…
Provisions are still vague. Releases are indeed unpredictable, said Michael Preston, general manager of the Dolores Water Conservancy District. The Bureau of Reclamation factors in current reservoir levels with never-perfect forecasts. Then there’s juggling ever-increasing demand: Farmers combine for the largest allocation of the supply, recent spreadsheets show, followed by the downstream fishery, tribe and municipalities.
“McPhee is a hard-working reservoir,” Preston said. “We use every inch of our active storage capacity to take care of things.”
The height of that arch is reached at Snaggletooth, the legendary Class IV rapid aptly named. Swirling eddies are like mouths ready to inhale, the jumble of rocks like jaws ready to chomp.
From an embankment, we stopped to analyze the beast. And yes, [Christian] Wright was scared. “If someone says they’re not scared, don’t get in their boat,” he said.
FromThe Cortez Journal (Jim Mimiaga) via The Durango Herald:
A 10-day whitewater boating release is planned for the Dolores River below McPhee dam and reservoir, managers said this week.
The recreational water flows will be let out from Tuesday to May 30 and are scheduled to accommodate boaters over Memorial Day weekend.
“Timing the release early for the three-day holiday was a big interest for the boating community,” said Mike Preston, general manager for the Dolores Water Conservancy District.
Beginning Tuesday, the managed “spill” will increase at a rate of 400 cubic feet per second per day to achieve a 1,200 cfs flow by the morning of May 24. The high flow will be maintained through May 27, then ramp down to 800 cfs through noon May 30. A gradual ramp down over a few days will follow.
However, the managed release is expected to continue after May 30, but to what extent has not yet been determined, water officials said.
Winter snowpack that reached 140% of normal is enough to fill McPhee Reservoir and provide the boating release below the dam. Recent cooler and rainy weather in Southwest Colorado has slowed the snowpack runoff, creating uncertainty about the final timing…
The inflow rate will depend on hard-to-predict temperatures and potential rain in the coming weeks. McPhee is expected to reach full capacity by mid-June, said district engineer Ken Curtis, and all irrigators will get a full supply for the season…
The 97-mile stretch of the Dolores River below the dam from Bradfield Bridge to Bedrock is revered by boaters for its challenging rapids and remote, red-rock canyon wilderness.
The three- to five-day Slick Rock-to-Bedrock section through winding Slick Rock Canyon offers a pristine river running experience. The 18-mile, one-day Ponderosa Gorge has convenient access and fills with locals and tourists when the river runs. No permit is required to boat the Dolores River.
The expert Snaggletooth Rapid is especially notorious for drenching boaters and occasionally flipping boats. A road along the river accessed from Dove Creek is a popular spot to spend the day watching boaters negotiate the wild hydraulics created by the rapid’s “fangs.”
Also this week, temperature suppression flows of 100 cfs were released from the dam to benefit the downstream native fishery. The strategy is to delay the spawning of the bluehead and flannelmouth suckers and roundtail chub until after the whitewater release.
Aquatic biologist Jim White, of Colorado Parks and Wildlife, spoke at a community meeting in Dolores about planned fish surveys, population data and survey techniques.
Parks and Wildlife works with McPhee Reservoir managers to manage downstream flows for three native species that reside in the Lower Dolores – the roundtail chub, bluehead sucker and flannelmouth sucker. The first several miles below the dam to Bradfield Bridge is managed as a cold-water fishery for brown and rainbow trout.
“Roundtail populations have been good,” White said, “and bluehead and flannelmouth are not as abundant.”
The reservoir holds a 33,500 acre-foot reserve for the native fish needs. The “fish pool” is released gradually throughout the year base on biologists’ input. In the winter, flows below the dam are 20-30 cubic feet per second. During summer, they reach 60-80 cfs if there is no whitewater release.
During low water years, the fish pool and farmers share in shortages. When there is a recreation dam release like this year, it is not counted against the fish pool, and the higher flows are managed for ecological benefits such as channel scouring, timing to benefit the fish spawn, and flood plain sedimentation that replenishes nutrient rich sediment on the banks for new seedlings…
Fish counts and surveys are done each year at Slick Rock Canyon, Dove Creek Pump Station, Pyramid Mountain and below the San Miguel confluence.
White explained how a “pit-tag array” installed in 2013 to monitor native fish on the Lower Dolores River works. It is just upstream from the Disappointment Creek confluence.
Native fish captured throughout the Lower Dolores are inserted with a electronic tag, and when they move past the “array” wire above the river, the movement and fish identification is recorded.
So far, 1,421 fish have been tagged. Of those, 38 percent were flannelmouth suckers, 35 were roundtail chubs, and 23 percent were bluehead suckers. Four percent were smallmouth bass, a non-native species biologists are trying to get rid of because they prey on young native fish.
Since installed, 157 tagged fish have been recorded passing under the pit-tag array. In 2018, 14 fish were detected, including eight flannelmouth that arrived after April 8. Five of the flannelmouth were tagged in Slick Rock Canyon, two in the Pyramid Mountain Reach and one tagged in 2014 in the San Miguel River.
The first native fish of 2019 passed under the array on April 5. It was last detected on Oct. 18. On April 16, two flannelmouth were recorded.
The Bureau of Reclamation will host the 2019 operations meeting for the Dolores Project on Thursday, April 18, at 7 p.m. The meeting will be held at the Dolores Community Center, 400 Riverside Avenue in Dolores, Colorado.
“This meeting is a great opportunity for our partners and the public to find out how the 2019 water year is shaping up and to have any related questions answered,” said Western Colorado Area Office Manager Ed Warner.
Meeting topics will include a review of 2018 operations, projected water supplies and runoff for 2019 and the forecasted possibility of a boatable release to the Dolores River below McPhee Dam in 2019.
The meeting will also include presentations and representation from several agencies, including: Reclamation, Bureau of Land Management, United States Forest Service, Dolores Water Conservancy District, Colorado Parks and Wildlife, Dolores River Boating Advocates, American Whitewater and Fort Lewis College. There will be opportunities for questions, comments, and discussion during the meeting.

Narraguinnep and Groundhog reservoirs are at their lowest level in 16 years, said Brandon Johnson, general manager for the Montezuma Valley Irrigation Co.
The limited water supply caused a reduction in allocations for MVIC shareholders Thursday to 36 inches, or 3 acre-feet per share. Shareholders who have reached that allocation will be shut off on Friday…
During normal snowpack years, a full allocation is 48 inches, or 4 acre-feet per share…
Groundhog Reservoir has a capacity of 21,700 acre-feet, but is at 11,000 acre-feet right now, Johnson said. It is expected to be drawn down to the minimum level of 4,000 acre-feet that is required for the fish pool.
During normal years, Groundhog is kept at 13,000 acre-feet going into winter.
“It will take two to three years of normal winters to refill Groundhog,” Johnson said.
MVIC owns Groundhog and Narraguinnep and also has storage and water rights in McPhee Reservoir. MVIC officials are releasing water from Groundhog, via the Dolores River, into McPhee to be delivered into the MVIC canal system.
As a result, the Dolores River is running at 182 cubic feet per second, but 150 cfs of that is coming from the Groundhog Reservoir release.
The irrigation supply in McPhee Reservoir is also running low, but the system is still delivering water, said engineer Ken Curtis.
Farmers had shortages this year, and the season was reduced from the usual three cuttings of alfalfa to two cuttings for most farmers.
During average years, irrigation supply in McPhee is 240,000 acre-feet of water, but this year, only 150,000 acre-feet was available, or 60 percent of normal. And most of the supply was carried over from the previous above-average winter.
There will be no carryover going into next year’s water season.
Pump-back storage systems utilize two reservoirs at different elevations. To generate power, water is released from the upper reservoir to the lower, powering a turbine on the way down that is connected to the grid.
In 2014, the Dolores Water Conservancy District released an investor’s memorandum on the potential for a project at Plateau Creek to inform energy companies and investors of the opportunity. The canyon’s steep vertical drop in a short distance makes it a good location.
District General Manager Mike Preston, speaking at Thursday’s board meeting, described pump-back storage plant idea as giant battery that is part of a green energy power grid.
When electric prices are high, the water is released from the upper reservoir through a turbine, and the power is sold to the grid to meet demand. When electric prices are low, the water is pumped back to the upper reservoir through a tunnel, recharging the battery.
Preston recently toured the Plateau Creek site by plane with Carl Borquist, president of Absaroka Energy, of Montana. The company proposed to build a pump-back hydroelectric facility at Gordon Butte, northwest of Billings, Montana…
The Dolores Water Conservancy District holds the water rights for the potential Plateau Creek project, estimated to cost $1 billion, based on the 2014 study. It would require environmental reviews and approval because it would be on San Juan National Forest land. McPhee could be used as the lower reservoir, with a small reservoir built above Plateau Canyon.
The project needs investors before it could get off the ground, but once online, it would generate an estimated $100 million per year in electricity sales. As the holder of the water rights, the district could benefit financially from the deal.
“We have the site, and if we could realize a revenue stream, it would help the district financially,” Preston said.
Shortly after Absaroka Energy’s visit, the district received a letter from Matthew Shapiro, CEO of Gridflex Energy, based in Boise, Idaho, expressing interest in exploring a pump-back storage system at McPhee.
“We recently developed a concept for this site that the district may not have considered before, one which we believe would have greater viability than the prior concept,” he stated. “We believe that the timing for this particular project is promising.”
Pump-back hydroelectric storage is considered a nonconsumptive, green energy power source. Energy companies are potential investors in hydro projects as they expand their portfolios to include green energy. They need supplemental sources to meet demand when the sun does not shine or the wind does not blow.
The Dolores Water Conservancy District had obtained a preliminary permit for a facility at Plateau Creek from the Federal Energy Regulatory Commission, but it was not renewed in 2016 because the project had not moved forward enough.

A new book puts the Gold King Mine spill within the long history of mining and pollution in Southwest Colorado.
Jonathan Thompson will be at the Book Bar tonight. I wonder if Denver is a bit of a shock to his system even though he’s a sixth-generation Coloradan?
I am so happy to finally get to finally meet Jonathan. His new book, River of Lost Souls, is an important read. Understanding the industrialization of our state over the years will help us chart a less destructive course.
I loved the passages where Jonathan reminisces about spending time around the Four Corners and in the San Juans. He transports you to those times in your life spent next to the river or exploring what sights the land has to offer. He connects you to the Four Corners in a way that only a son of the San Juans could.

Collaboration in the Dolores River Watershed (Celene Hawkins):
About one year ago, I was backcountry skiing into some of the highest elevations of the Dolores River watershed near Lizard Head Pass. I was appreciating the above-average snowpack that Mother Nature blessed the basin with, which covered the always-spectacular beauty of the San Juan Mountains.
Over the course of 2017, I got to visit and revisit that snowpack as it melted and flowed down the upper portions of the Dolores watershed, filled McPhee Reservoir (where it would serve important municipal, industrial, agricultural, and Tribal uses), and provided enough water for a rare and large managed release from McPhee Reservoir into the lower Dolores River.
Because the Dolores River watershed has experienced so few recent years of abundant water, the abundant 2017 water year provided cause for local and regional celebration. Local farmers had full supplies of water from the Dolores Project to support their agricultural operations, recreational users of the Dolores River below McPhee Dam enjoyed a whitewater boating season of 63 days, and the entire ecology of the Dolores River benefitted from the longest and highest flows experienced in a decade.
Yet, now, in January 2018, I’m watching one of the driest and warmest early winters in recent history, reflecting on local water work in 2017. The bigger and more interesting story in the Dolores River watershed is not one about the snowpack or water supplies, but is instead one about collaborative water and resource management work in the watershed.
Collaborative work can take a significant amount of time and resources from already-taxed governmental agencies and non-profit groups. Collaborative work around water and watershed management requires a delicate balance of a proper respect for important private property interests in the use and delivery of critical water supplies, and the ability to find creative solutions and projects to protect the wider public and resource management interests, as well as private industry, that rely on the same river and watershed. On the Dolores River, water managers; federal, state, local, and Tribal governmental agencies; non- profit groups; local industry; private citizens; and others are working throughout the watershed to address important and often difficult water and natural resource management challenges.
Two major collaborative efforts on the Dolores River saw significant growth and success in 2017, and it is worth celebrating now and continuing to watch and support in 2018.
The Upper Watershed—Dolores Watershed Resilient Forest Collaborative
In 2015, Firewise of Southwest Colorado and the Dolores Water Conservancy District launched a new effort to form a collaborative network in the Dolores River watershed to address community wildlife and post-fire risks at a watershed scale. This new collaborative effort recognizes that droughts, beetle infestation, and a perennially longer fire season are all setting the stage for a broad-scale natural disaster in the forested upper Dolores River watershed. The potential for such a natural disaster puts at risk community lives, property, and public and natural resources (including the water in McPhee Reservoir that supports cities, farms and ranches, industry, and rural areas in the Montezuma Valley).
Momentum for establishing and growing capacity in the Dolores Watershed Resilient Forest Collaborative (known by the charming acronym of the “DWRF Collaborative”) has been tremendous over the last two and a half years. By the end of 2017, over 40 different public and private entities were participating at some level in the collaborative.
Some example partners include: the Dolores Water Conservancy District, Montezuma and Dolores counties, the towns of Dolores and Dove Creek and the City of Cortez, the Ute Mountain Ute Tribe, San Juan National Forest, Colorado State Forest Service, Tres Rios BLM, representatives of the local timber industry (including Aspen Wall Wood, Findley Logging, Montrose Forest Products, and Stonertop Lumber), conservation organizations (including Mountain Studies Institute, San Juan Citizens Alliance, The Nature Conservancy, and Trout Unlimited), and private citizens.
The DWRF Collaborative has also successfully garnered resources to support capacity building within the organization, including the impressive coordination work of Rebecca Samulski, Assistant Director for Firewise of Southwest Colorado. She says, “The stakeholders continue to show up each month and share the workload. It is inspiring to see the conversations that continue after each stakeholder meeting, then to hear about the efforts that have emerged among participants because the DWRF Collaborative has gotten them in a room together.”
The group has already undertaken an impressive mix of “on the ground” forestry and fire- adaptive treatment projects, planning work, and engaging on key issues in the upper Dolores watershed. In 2016 and 2017, the DWRF Collaborative implemented forestry and fire- adaptive treatment projects near Joe Moore Reservoir (Lost Canyon tributary) and on Granath Mesa, which sits directly above McPhee Reservoir and the Town of Dolores.
The DWRF Collaborative has allowed the San Juan National Forest to establish Good Neighbor Authority projects with the Colorado State Forest Service (bringing additional capacity and resources to accomplish cross boundary projects on private lands and adjacent national forest lands).
The DWRF collaborative has also completed modeling of wildfire risk and post-fire flooding and erosion risk that will inform a Watershed Wildfire Protection Plan with a better understanding of how wildfires are likely to affect key community values (such as public safety, structures, infrastructure, and water resources) and how to target future treatment projects.
Finally, the DWRF collaborative has launched into key local issues in the Dolores River watershed through professional background presentations to the stakeholders and working groups. These efforts include engagement and support of the local timber industry to explore opportunities that will make forest restoration for watershed protection more cost effective.
An emerging bark beetle epidemic in the Dolores River watershed is another key issue that the collaborative is developing local strategies for, such as an identification and management workshop series to launch in 2018.
Below McPhee Dam—Dolores River Native Fish Monitoring and Recommendation Team
Water managers and diverse groups of stakeholders have been engaged in collaborative work on the Dolores River below McPhee Dam for more than a decade. For example, the Dolores River Restoration Partnership (a public-private partnership) has been working hard and successfully since 2009 to restore the riparian corridor of the Dolores River below McPhee Dam. They have worked to control invasive plant species and restore riparian vegetation.
Since the Dolores River Dialogue (DRD) re-initiated discussions about the Dolores River downstream ecology in 2004, water managers and a large and diverse group of stakeholders have been working to address some of the toughest land, resource, and water management challenges facing McPhee Reservoir and the Dolores River below McPhee Dam.
In 2017, the Dolores River Native Fish Monitoring and Recommendation Team (M&R Team), tasked with monitoring changes to the downstream river ecology, really stepped up to provide guidance and monitoring work on the largest managed release from McPhee Reservoir in more than a decade. The M&R Team was formed during a multi-year, science-driven collaborative planning process around the needs of the sensitive, native warm-water fisheries in the Dolores River that resulted in the finalization of the Lower Dolores River Implementation, Monitoring and Evaluation Plan for Native Fish (2014) (“2014 Plan”). Both the 2014 Plan and the M&R Team’s work to help implement opportunities identified in the plan are guided by the DRD purpose statement, which is “. . . to explore management opportunities, build support for and take action to improve the ecological conditions in the Dolores River downstream of McPhee Reservoir while honoring water rights, protecting agricultural and municipal supplies, and the continued enjoyment of boating and fishing.”
Because the 2014 Plan was finalized in the middle of a tough span of especially dry years on the Dolores River, the M&R Team was not able to use the 2014 Plan to help guide the management of any significant releases of surplus water from McPhee Dam for ecological and other purposes for several years. However, in 2017, the combination of an above-average snowpack in the San Juan Mountains in the Dolores River basin and good carry-over storage from 2016 in McPhee Reservoir provided water managers and the M&R Team with the opportunity to shape the largest managed release of surplus water from McPhee Dam in more than a decade.
Armed with the 2014 Plan (and a diverse team that includes the Dolores Water Conservancy District, Montezuma Valley Irrigation Company, the Bureau of Reclamation, the Tres Rios Field Office, Bureau of Land Management, San Juan National Forest, Ute Mountain Ute Tribe, Colorado Parks & Wildlife, Dolores, Montezuma, San Miguel, and Montrose counties, American Whitewater, The Nature Conservancy, Trout Unlimited, and San Juan Citizens Alliance) the M&R Team was able to help water managers begin to make decisions about how to plan for the large managed release as early as February of 2017.
Sample hydrographs and ecological targets developed in the 2014 Plan were adapted for use with the specific forecasting for the Dolores River Basin’s 2017 water year to help shape a release plan that included a “peak flow” release of 4,000 cfs to support fish habitat maintenance on the Dolores River. Recreational and conservation interests from the M&R Team (American Whitewater and The Nature Conservancy), Colorado Parks & Wildlife, the Bureau of Land Management, and the Dolores River Boating Advocates all worked closely with the Dolores Water Conservancy District and the Bureau of Reclamation to assist the water managers with necessary adjustments to the release plan as the water managers addressed a wildly-fluctuating forecast and runoff pattern on the Dolores River in the spring of 2017.
In addition, flow hypotheses and measurable benchmarks from the 2014 Plan allowed members of the M&R Team to set up and deploy field monitoring along the Dolores River below McPhee Dam. Armed with years of scientific research and the 2014 Plan, Colorado Parks & Wildlife and The Nature Conservancy were able to develop an ecological monitoring plan and pull together a collaborative group of researchers to set up monitoring sites on the river within a few weeks of the first M&R Team meeting and notification from the Bureau of Reclamation about the potential magnitude of the 2017 managed release. American Whitewater and the Dolores River Boating Advocates launched a boater survey to evaluate recreational use of the Dolores River below McPhee Dam. Colorado Parks & Wildlife also deployed several fish monitoring crews on the Dolores River during the managed release, including undertaking a challenging fish survey in the remote Slickrock Canyon (which had last been surveyed in 2007) that provided important information on the status of the sensitive, native warm-water fisheries in that stretch of the river.
The collaborative research team is continuing to work on analyzing the results of this monitoring work over the winter of 2017-2018 to provide information to the M&R Team and water managers that may help inform future releases and other management efforts on the Dolores River.
“In 2017 we finally had the snowpack we needed to conduct and monitor a large managed release. In addition to the snowpack, mother nature also provided March warming driving early release, declining forecasts and wide temperature swings.
The fact that all ecological and water supply goals were met is due to the flexibility of the researchers working closely with reservoir managers. We shared in the responsibility for keeping all constituencies informed. Providing large and extended ecological releases with the assurance that all water obligations would be met and McPhee reservoir filled could only happen with this level of cooperation. Having this level of information and communication in managing and assessing a multiple- objective release was a water manager’s dream.” — Mike Preston, General Manager, Dolores Water Conservancy District.
Collaboration into 2018 and Beyond
The grim SNOTEL report for southwestern Colorado (sitting at 36 percent of average and just 21 percent of what we had in 2017 as of the end of January) and the current spring forecasts have many water managers and interests planning for a year of “famine” in 2018, after the relative water “feast” that occurred just a year ago in 2017. The increasing uncertainty around snowpack, water availability, and the timing of runoff that we are experiencing in southwestern Colorado, as well as other drivers of wildfire risk, will continue to be powerful motivators for collaborative work in the Dolores River watershed.
I look forward to supporting these continued collaborative efforts, through feast and famine, in this iconic Colorado watershed.
A coalition of local government agencies that formed to prevent an invasive mussel contamination at McPhee Reservoir can claim victory in its first year.
A test in October showed no sign of the dreaded quagga or zebra mussels, which proliferate rapidly and can attach in suffocating layers to irrigation and municipal infrastructure.
“With the help of the community, we have avoided contamination and protected our water source,” Ken Curtis, an engineer with the Dolores Water Conservancy District, said during a recent community meeting to gather public comment.
The success is credited to stringent new rules that require all motorized and trailered boats to go through mussel inspection stations at either the House Creek or McPhee boat ramps during open hours. Mussels are carried in standing water of engines and ballasts.
Restricted access changed the culture of McPhee access.
McPhee Reservoir is seeing increased use this summer because of decreased opportunities for motorized boating on other Southwest Colorado reservoirs that have been closed to guard against the introduction of aquatic nuisance species, according to the San Juan National Forest.
And to accommodate boaters during the July Fourth holiday, the inspection station for the House Creek boat ramp will extend its hours to 6 a.m. to 8 p.m. Friday through Tuesday, the forest said in a news release.
The inspection station at the more crowded McPhee boat ramp will remain open seven days a week from 6 a.m. to 8 p.m. All other access points to McPhee Reservoir have been gated to prevent uninspected boats from entering the reservoir.
McPhee is one of a few reservoirs in Southwest Colorado with mussel inspection stations that allow for motorized boating, public affairs specialist Ann Bond said in the news release.
The McPhee boat ramp has seen an 85 percent increase in inspections this summer from last year, Bond said.
“Because of the increased usage, parking areas and boat ramps are experiencing congestion, especially on weekends,” she said. “The U.S. Forest Service urges visitors to use parking areas and ramps as efficiently as possible to lessen congestion.”
The Forest Service encourages boaters to prep their craft before launching to reduce time at the ramp and to follow traffic signs to ensure safety for all visitors. Boaters who park vehicles without trailers are asked to use overflow parking areas to leave the larger parking areas available for trailers. Weekday users will find less crowded conditions.
Weekend users are encouraged to use the House Creek boat ramp, which is often less crowded.
Inspection stations are working smoothly, with previously inspected boats carrying documentation and tags moving through the process within 10 minutes. Boats that have not been cleaned, drained and dried – and require decontamination procedures – are urged to enter inspection stations during weekdays, because the decontamination process takes more time.

Like a Frenchman knows good years and bad years for wine, I remember years in Colorado for their snowpack. In 1995, deep snow remained well into summer. In 2002, the snow never came and Coloradans were reminded of how bad drought can be. In 2011, the snow at my family’s favorite backcountry ski trailhead was still 10 feet deep in early May. In 2012, it was drought again; later that summer fires raged west of my home in Fort Collins.
Water from this snowpack is the proverbial lifeblood of Rocky Mountain rivers. In fact, water is the lifeblood of the entire economy of the West—for brewers in cities, for corn growers east of Fort Collins, and for angling guides in our high county. Competition for water can be fierce.
Residents of the Southwest weren’t yet competing for water in 1776 when two Spanish priests — Francisco Atanacio Dominguez and Silvestre Valez de Escalante — christened one of our lifeblood rivers, El Rio de Nuestra Senora de las Dolores. Better known as the Dolores — the Sorrows — many view this epithet as reflecting the current state of the river. In 1983, the gates closed on the McPhee Dam, one of the last projects during the United States Bureau of Reclamation’s era of big dams. Within a decade, a series of dry years came along and a fight exploded over the impacts of the dam on the ecology of the river.
With its origins in the high, remote mountains near Telluride in southwest Colorado, the Dolores is a river of extremes. Fed by snowmelt gushing off the Rocky Mountains, spring flood flows before the dam could reach 1000 times the low flows of late summer. The reason people dam rivers is to make the water supply — in this case irrigation water — more predictable. Capture the spring snowmelt in a reservoir. Send the water to farm fields later in the summer. That’s good for farmers. But it’s bad for native fish.
At the time of Dominguez and Escalante, only about half a dozen fish species lived in the 175 miles of river now below McPhee Dam. These fish are all built for extremes. Aerodynamic bodies help them withstand huge floods. Tolerance for hot temperatures allow them to wait out low, warm waters during drought. Some of these fish can detect chemical and electrical signals of their prey, so they can hunt in dark murky water. Many can live for decades, allowing populations to survive a string of bad years with little or no reproduction.
The best known native of the Dolores is America’s largest minnow: the Colorado pikeminnow. The pikeminnow can reach 6 feet long and weigh up to 80 pounds. One hundred years ago, pikeminnow were so abundant that fishermen would haul them out of rivers with pitchforks. Pikeminnow harvests even supported a commercial cannery near Yuma, Arizona. This species has been around for more than 3 million years. But after just a few decades of 20th century dam building, they were nearly extinct.
Here’s a report from Jason Blevins writing for The Denver Post. Click through and read the whole article. Here’s an excerpt:
The fickle Dolores River is emblematic of Western water woes, where increasing recreation demands and calls for conservation clash with traditional uses that quench arid towns and farms.
That tension has created conflict in the past, as the river veers from tidal to trickle. There’s no other way to see Slickrock Canyon except by boat, and without raft-floating flows, the canyon is essentially closed.
But, recently, the Dolores River water wrangling has yielded collaboration. And this year, after more than a decade of planning, a diverse team of water users — including water managers, farmers, boaters, conservationists, ecologists and land managers — have galvanized to celebrate and study more than 60 days of boatable flows, creating one of the most vibrant seasons in recent memory on the miles of varying Dolores River below McPhee.
“It’s been a ghost and you have to chase it,” said Schafer, the Western Slope advocacy director for Conservation Colorado, who first navigated Slickrock Canyon during a quick, small release last year. “These last couple years have really opened my eyes to the complexities of Western water policy, the complexities of public land management and the complexities recreation management. But at the end of the day, the overwhelming experience is sheer and utter beauty. This is one of the most spectacular river canyons on the planet.”
The Lower Dolores River through Slickrock Canyon — traversing a 30,000-acre Bureau of Land Management wilderness study area — offers geology spanning hundreds of millions of years.
Entrenched channels carve through Wingate Sandstone, the Kayenta Formation and Navajo Sandstone layers that tower hundreds of feet above the river. Panels of petroglyphs and pictographs reveal the canyon’s millennia-old appeal. Ancestral Puebloan, Archaic and Fremont people frequented the remote canyon. Several pictographs and petroglyphs in the canyon show the horned Fremont Man and bear paws. Some of that artwork is near dinosaur tracks…
Those capricious flows have defined the Lower Dolores since the Bureau of Reclamation finished building the McPhee Dam in 1984. McPhee Reservoir, managed by the Dolores River Water Conservancy District, holds roughly 380,000 acre-feet of water, most of it allocated for agricultural use around the Four Corners region.
In 2004, Dolores River stakeholders gathered to forge a unified mission. The group included the water conservancy district; irrigation users; the Bureau of Reclamation, which owns the dam; the Bureau of Land Management; conservation groups; boater groups such as American Whitewater; and Colorado Parks and Wildlife. That mission outlined how the groups can work together to help boaters — who have a legal right to excess water in McPhee Reservoir — and ecologists eager to protect fish habitat while honoring water rights and allocations for irrigation and municipal uses…
It took almost a decade of meetings — during, incidentally, a prolonged drought that pretty much eliminated releases of unallocated water from McPhee — to hammer out a plan that bolstered fish habitat and maximized recreational flows for boaters.
The Lower Dolores Implementation, Monitoring and Evaluation Plan created a team that helped to manage releases. This year, with a healthy snowpack and good carryover water levels from the previous spring melt, American Whitewater helped negotiate significant releases from McPhee — from the end of March to May 21 and another surprise burst last week.
The surges, including a high-flow, three-day pulse of 4,000 cubic feet per second that limited the length of the boating season but helped restore riparian habitat, marked the largest releases since 2008. The flows drew wildlife scientists, conservationists and boaters in droves.
“We are trying to align everyone’s activities so they all fit together, and this was a really successful year for that effort,” said Michael Preston, manager of the Dolores River Water Conservancy District. “We had really great monitoring this season. We have a plan. We have objectives. We are going to start learning a great deal.”
The Nature Conservancy and Colorado Parks and Wildlife worked together in March to study the deeply channelized river bed before the big flow and then again in April and May to observe the river during a variety of flows. The hope was the big pulse and the sustained flows helped push the river out of its entrenched channel, allowing it to scour riverbanks of dense willows and alder, and restore eddies and backwaters…
Jim White, an aquatic biologist with Colorado Parks and Wildlife, got onto the Dolores River below McPhee last month for the first time since 1990. He was looking for endemic populations of roundtail chub, bluehead sucker and flannelmouth sucker fish. He found all three in Slickrock Canyon. His team did not find any smallmouth bass, which can decimate native fish populations. That’s all good news…
“The main thing we want to do is make sure we don’t lose any more ground in terms of the fishery. The density of fish is pretty low, but all three species are present,” says White, who tagged more than 500 fish that can be followed through antennas set above and below Slickrock Canyon. “They are using the habitat in Slickrock and other sections of river. Having a good water year like this helped. Everyone was on the same page. The 4,000 cfs disrupted the channel and … created better fish habitat.”
While scientists surveyed fish, American Whitewater and the Dolores River Boating Advocates canvassed boaters. Conservationists and recreationists have united on the Dolores, merging their missions in a singular push for more water.
The boater survey is trying to quantify the economic impact of boaters rallying in the West End of Montrose County. Paddling advocates want to know whether the flows were announced early enough and whether the timing of the releases offered enough opportunity to float through the wild canyons of the Dolores River.
Early reports show crowding was not an issue, but boaters — almost all of them private paddlers — lamented the accessibility of potential campsites: unimproved sandy beaches that haven’t really been used for several years. Most of the river bank through Slickrock is densely armored with virtually impenetrable willows. Upstream, in Ponderosa Gorge, where the lush mountain river transitions to a red-walled desert canyon, impassable alder thickets guard the banks.
“American Whitewater negotiated a high-flow release, hoping it would help recover fish and habitat. That meant a shorter season. But we will trade a few days if we can get that water down there to work for a healthier ecology,” says American Whitewater’s Nathan Fey.
Rafters rally when the Dolores runs. They come from across the West, with trailers from several states stacked more than a hundred deep at the Bedrock takeout on a Sunday in mid-May…
With McPhee Reservoir pretty much full a month-and-a-half into irrigation season, there’s a good chance that releases will happen again next year, especially if winter snowpack is around normal. Water users, Preston says, are upgrading sprinkler technology, reducing irrigation demand.
McPhee Reservoir managers have announced that rafting flows on the Dolores River below the dam will start up again for at least a few days next week.
On Monday, June 5, flows will begin ramping up by 100 cubic feet per second every three hours. By Tuesday noon, flows will be 800 cfs and continue until Thursday or Friday, possibly longer…
Record winter snowpack easily filled the reservoir and provided for a 52-day rafting season that ended May 25 so the reservoir could be topped off. But lingering high-mountain snows continue to provide ample runoff that is more than the reservoir can hold, so another release is necessary.
Curtis said the three-day release could extend to five or longer depending on inflows and weather. Managers will be giving daily updates beginning Monday on the release schedule.
The Colorado Basin River Forecast Center is predicting an increase of inflows into McPhee this weekend. Depending on actual volume, the latest rafting release could be up to a week or 10 days, officials said.
To accommodate boaters on multiday trips, ramp-downs for this release will be slower than usual, dropping 100 cfs per day to allow time for boaters to get off the river.
About a dozen kids from Montezuma and Dolores counties got to experience that adventure thanks to a partnership between the Piñon Project, Dolores River Boating Advocates and the Onward Foundation.
The May 20 trip down Ponderosa Gorge was organized for youth ages 9 to 17 in the Piñon Project mentoring program, and for many of them, it was a first…
Mild to Wild rafting gave the group a discount rate, and it was paid for thanks to a grant from the Onward Foundation.
The goal was to introduce kids to the thrill of rafting and show off the natural wonders of a river in their own backyard, said Amber Clark, program coordinator for the Dolores River Boating Advocates…
The daylong excursion coincided with Colorado’s First Public Lands Day.
A guided boating trip down the Lower Dolores was extra special, Lacourciere said, because a run depends on a water release from McPhee reservoir upstream.
Plus, it was an opportunity for kids to experience an outdoor activity that is often inaccessible for families because of the expense of the boating gear and required river skills.
By midnight May 23, flows will ramp down to 600 cubic feet per second, hold for 24 hours, then drop to 400 cfs after midnight on May 24. From there the river will drop to 200 cfs, then 75 cfs by Sunday May 28.
“Spring runoff forecasts have steadily dropped with the drier-than-normal weather,” said Ken Curtis, an engineer with the Dolores Water Conservancy District. “It is time to fill the reservoir.”
Curtis said there is a chance that early hot June weather could bring down the remaining snowpack very quickly, which could force a mini whitewater spill of boatable flows for four to six days in June…
A solid winter snowpack allowed for the reservoir to fill for farmers and provide for 52 days of whitewater boating below the dam. In mid-May, 4,000 cfs of flushing flows were released for 72 hours to benefit river ecology, including sediment clearing and channel scouring, which improves native fish habitat. There were seven days of optimal flow releases of around 2,000 cfs.
A year-in-review meeting is being planned by reservoir managers, boaters, and environmental groups to evaluate the season.
A plan by Colorado Parks and Wildlife to flush out small-mouth bass opens up a slight window for kayakable flows later in the summer.
In mid July, biologists want to use part of their reserved fish pool in McPhee reservoir to release 400 cfs for 3-4 days and disrupt the bass spawn. The bass are a threat to the flannelmouth and bluehead suckers and roundtail chub, preying on their young and competing for food sources.
The U.S. Bureau of Reclamation just finished a controlled, peak release from the McPhee Reservoir that reached 4,000 cubic feet per second over the past weekend. The ramp down began Sunday, starting at 800 cfs per day until Thursday, May 11.
“This is a really exciting time on the Dolores River because of a combination of high carry over storage in McPhee Reservoir and a good snowpack has resulted in a fairly large managed release from McPhee Reservoir,” said Celene Hawkins of the Colorado Chapter of The Nature Conservancy. “Every seven to 10 years it happens that we’ll have as much water in the system that we’ll have this year. It’s a really important opportunity to manage those flows for the ecology downstream of McPhee Dam.”
She added that 4,000 cfs is the fastest the river has flowed since 2005. As of Monday, the river was at about 3,400 cfs, she said.
As the nature conservancy’s Western Colorado Water Project Manager, Hawkins is monitoring the impacts of the release throughout the whole river system. She is also the co-chair of the Dolores River Native Fish Monitoring and Recommendation Team, which aides the Dolores River Conservancy District.
“We’re doing a lot of monitoring around the release and particularly around this larger peak release to better understand what’s feasible within existing water supplies,” she said.”
Hawkins led a flyover tour of the Dolores River — from the McPhee Reservoir in Dolores to Bedrock in the West End of Montrose County — Monday afternoon. The LightHawk volunteer flight left from Durango’s Animas Air Park and was piloted by Jim Grady, who flew a pair of curious journalists around in his 1953, red-and-white Cessna 180.
Hawkins explained there are three monitoring sites: one in the Dove Creek region and two in the Slickrock area of the Gypsum Valley and near Bedrock. Monitoring includes analyzing the impacts the release has had on downstream ecology, including vegetation and animals. The monitoring isn’t a simple process, Hawkins said, as it will take multiple years to fully collect data and turn it into practical action items, if necessary. She added there are some immediate results of the release such as plains being flooded from the excess water, and later down the system, receding waterlines as a result of the ramp down.
“A big purpose of that release was to do sediment flushing and habitat maintenance,” she said…
“I was on the river during the peak release. It was the highest I had seen it,” said Hawkins, who traversed the river between Bradfield and Slickrock. “It felt like a celebration. People were looking out for each other.”
During the flyover, the Dolores River curved and curled through the Earth’s patchwork quilt of forest, farmland and free-living.
Rafters and kayakers could be spotted in almost every area of the river, appearing more like multicolored specs than anything else…
Organizations like the nature conservancy and the Dolores River Conservancy District work with various stakeholders, including recreational groups like the Dolores River Boating Advocates (DRBA).
“DRBA has been working really hard on the release this year; both communication to boaters and also communication with water managers to help shape the management of the release,” Program Coordinator Amber Clark said.
Hawkins added farm irrigation systems will most likely not be affected by the release.
“We have worked very closely with the water managers and the water users out of McPhee Reservoir to make sure that they will have their full supplies this year,” she said.
The flight lasted just over two hours and featured more than just views of the raging Dolores. Houses and barns looked like mini Monopoly pieces with their red and green roofs. At one point, several elk could be seen bathing in an isolated lake just south of Bedrock. Aerial views of the Ponderosa Gorge and Paradox Valley revealed several changes in colors throughout the rock walls; from tans to browns to reds, including greens from the area’s flora.
The Dolores River Monitoring and Recommendation team recently agreed on a plan to release water from the dam, which involved input from water managers, boaters, scientists, environmental groups, federal lands agencies, and local governments.
Surplus water is expected to spill from the McPhee Dam from April 13 until mid-June, with 45 to 60 days of flow planned at 2,000 cubic feet per second. Water managers plan to release an even larger burst of water, expected at 4,000 cfs, during three days in late May (May 19-22). Scientists say the extra water will flush extra sediment downstream and create better habitat for native fish.
“That’s a great flow level, something we haven’t seen in years,” says local rafter Sean McNamara. “Bring on Snaggletooth!”
Despite the extra water, water managers say all water allocations will be met, including those for agricultural use.
This year’s spill from McPhee Reservoir will be lengthy. Snowfall was particularly good this year. But a steady release is not what appeals to boaters. Better to vary the flow from high to medium levels to give river runners different experiences in the canyon…
A big Dolores spill does not occur often (the most recent of any size was in 2008), thus there are good reasons for making the most of it this year. Expect the river, ecology and terrain to be subjected to its dynamism.
Sediment movement with different flows is important as the river adjusts its pools and eddies while refreshing itself. And to what degree an underground aquifer will replenish depends on higher flows.
While Southwest Colorado will enjoy making the most of the Dolores, there are plenty of uncertainties about how to fund other water projects needed for a state population expected to double by 2050 (requiring an estimated 560,000 acre feet of water).
Both conservation and more efficient water uses are in the equation, but project funding is elusive. Severance taxes provide the bulk of the funding for the Department of Natural Resources, but energy extraction is not providing a predictable revenue source.
Flows on the Yampa River this week more closely resembled conditions typical of mid-July than mid-April, and federal scientists who keep an eye on the entire Colorado River Basin are now predicting that flows in the river, which runs through the heart of downtown Steamboat Springs, will trend below average through mid-summer.
“The headwaters of the Colorado River main stem and the San Juan Basin are currently forecast to receive near average runoff volumes, while the Yampa and White river basins now have forecasts for below average April-July runoff volumes,” hydrologists at the Colorado Basin River Forecast in Salt Lake City predict.
The Yampa was flowing at 309 cubic feet per second (cfs) at the Fifth Street Bridge in downtown Steamboat Springs at midday on April 13. That’s below the median for the date of 440 cfs. But this isn’t likely to be a replay of 2012 when the river peaked unusually early for the season at 1,570 cfs on April 27.
There is still 38 inches of snow on the West Summit of Rabbit Ears Pass, according to the Natural Resources Conservation Service.
Based on weather forecasts, the River Forecast Center expects the Yampa in Steamboat to spike to just over 400 cfs Friday, April 14 in the wake of temperatures pushing 70 degrees on Thursday, then retreat to below 230 cfs by April 21.
It’s a different story on the Elk River, which flows into the Yampa west of Steamboat. Contrary to the trend on the Yampa, the Elk was flowing well above average Thursday at 1,080 cfs, compared to the median 641 cfs…
The historic average peak flow for the Yampa is 3,070 cfs at the Fifth Street Bridge. The river peaked at 3,550 cfs on May 5, 2015, and at 3,430 cfs on June 9, 2016.
One of the heaviest runoffs this decade was in 2011, when the river peaked at 5,200 cfs on June 7. The highest recorded peak flow was 6,820 cfs on June 14, 1921, in an era when there were fewer dams upstream from Steamboat.
For several years The Nature Conservancy and its many partners have been studying the Dolores River ecosystem downstream of the McPhee Dam while working with water managers to improve the river’s health. It is well known that “taming” rivers, i.e. reducing or eliminating normal spring flooding, has major impacts on the flora and fauna. This year abundant snow and an abnormally warm spring have forced the Dolores Water Conservancy District to pull the lanyard on the spillway to keep the reservoir from flooding. The releases will start at around 800 cubic feet per second and will eventually reach 4000 cfs later in the spring.
All this is great news for people who care about healthy rivers. While not quite as powerful as a normal spring flood, the enhanced flows will clean sediment out of pools for fish and scour the riverbank and restore some of the flora, such as cottonwoods, to its more natural state.
To assess the changes, biologists and fluvial geomorphologists have been surveying the pre-release state of the river ecosystem. In our ongoing support efforts for The Conservancy, Agribotix volunteered to conduct aerial surveys of four sites downstream of the dam.
Agribotix founder, Tom McKinnon, flew the surveys along with Teresa Chapman, a GIS specialist at TNC. They flew both RGB and near IR cameras and returned the results as stitched mosaics at 5 cm ground sampling distance. The field mission went off without a hitch, except for a powerful spring storm that had southwestern Colorado in its sights. Fortunately the team was able to complete the final flight just minutes before the rain arrived. We’ll be headed back later in the summer for the post-release survey.
Flows on the upper Dolores River above McPhee Reservoir were at 1,000 cubic feet per second (cfs) as of Sunday.
Below McPhee Dam, a 60-day whitewater release is planned, with initial ramp-up of 400 cfs per day starting on April 11. By April 16, rafting flows will reach 2,000 cfs, and stay there for 30 days.
In the third week of May, managers will release flushing flows of 4,000 cfs for several days to provide ecological benefits to the river. The high flows mimic a natural spring hydrograph, and benefit the river by scouring the channel, redistributing cobbles for fish spawning and improving pool habitat for native fish species. Flood-plain inundation also helps generate native vegetation growth by spreading seeds beyond the main channel.
After the spike in flows, the river will return to 2,000 cfs for the Memorial Day weekend, with ramp-down of 400 cfs per day expected in early June…
Natural flows at Slick Rock Canyon
Even without the dam release, low-elevation snowmelt has already boosted river flows on the Slick Rock to Bedrock section to 600 cfs and higher, enough for a canoe, kayak or small raft. The popular 50-mile section features Class II and III rapids in remote red-rock canyon country…
The main Lower Dolores River boating run stretches for 100 miles through winding, red-rock canyons interspersed with rapids ranging from Class I to Class IV, including the famed Snaggletooth Rapid at mile marker 27. The Lower Dolores River is considered one of the premiere multiday boat trips in the nation when it has enough water to run. No permit is required.
In the past, when there was a whitewater release, McPhee Reservoir managers targeted 800 cfs for as long as possible below McPhee Dam. But after hearing from boaters in the past few years, the release level was adjusted to the preferred 2,000 cfs flow whenever possible.
“The water managers have made a huge effort to listen to the boating community,” said Sam Carter, of the Dolores River Boating Advocates.
For updates on the whitewater release schedule, go to http://doloreswater.com/releases/ The next update will be April 5. Once the spill begins, regular updates will occur on Mondays and Thursdays.
Meanwhile, the higher flows are an opportunity for scientists to study river ecology. Here’s a report from Jim Mimiaga writing for The Cortez Journal. Here’s an excerpt:
Biologists with Colorado Parks and Wildlife will do fish counts on native and non-native populations, and conduct habitat improvement measures.
The Nature Conservancy, Fort Lewis College and American Whitewater will be studying geomorphology, benefits of flushing flows and recreational boating conditions…
“We have a lot of opportunity this year for fish sampling and monitoring,” said Jim White, a fish biologist for Parks and Wildlife, during a presentation Thursday at the Dolores Water Conservancy office.
His team will be studying population health of three native fish in the Lower Dolores: the roundtail chub, flannelmouth sucker and bluehead sucker.
One of their objectives is to measure the non-native small-mouth bass population, then work toward reducing them. Small-mouth bass are a threat to native fish, preying on their young and competing for food sources.
“We want to find out how widespread small-mouth bass are, especially if they are established in Slick Rock Canyon,” White said.
The bass have developed a stronghold upstream from Slick Rock Canyon to Snaggletooth Rapid. But the high runoff year has opened up an opportunity to try and take out small-mouth bass, White said. In mid-July, Parks and Wildlife plans a flush of 400 cubic feet per second (cfs) for 3-4 days from its fish pool reserves within McPhee Reservoir to disrupt the small-mouth bass spawn…
Parks and Wildlife manages a 32,000 acre feet “fish pool” in McPhee Reservoir for minimum base flows releases below the dam.
During a whitewater release, the fish pool is not debited, White said, giving fish biologists more flexibility in how to use it. They will tap into 2,600 acre feet of the reserve for the bass-removal flush.
The Nature Conservancy is sending a team of researchers to the Lower Dolores for 10-15 days, said Colorado chapter representative Celine Hawkins.
Their work plan includes studying sediment transport and flood-plain inundation, which is needed to widely distribute native seeds. They are especially interested in the impact 4,000 cfs peak flows will have on scouring the river channel…
The Nature Conservancy will be using drones to take aerial photos of the Lower Dolores before and after peak flows to track changes and compare them to past years.
They are focusing monitoring efforts at Disappointment Creek, Dove Creek Pumps, Big Gypsum Valley and Bedrock.
Students at Fort Lewis College will be conducting ecological monitoring on the river as well, including on the alluvial groundwater aquifer…
2016 study results on Lower Dolores
Colorado Parks and Wildlife shared results of a 2016 fish study on the Dolores River.
A cold-water fishery sampling below the dam showed two-thirds brown trout and 16 percent rainbow trout.
Algae due to infrequent flushing flows is abundant in the 12 miles of stream immediately below the dam. There is a concern it could have a negative impact on fish.
In June, the 20-mile Ponderosa Gorge section (Bradfield Bridge to Dove Creek pump house) was surveyed. Of the 180 fish caught, 73 percent were brown trout, and roundtail chub was the second-most abundant. No small-mouth bass were found in the gorge.
Sampling at the Dove Creek pump station showed roundtail chub were holding steady, in part because they are an adapted pool species. Bluehead and flannelmouth suckers were in relative low abundance, and depend more on a ripple environment. In 1992, fish sampling showed much higher numbers of native fish species, the study noted.
“The impact of flushing flows in (2016) was evident, and backwaters looked cleaner,” according to study results.
The past two years, Parks and Wildlife has been stocking bluehead suckers in the Lower Dolores. The fish historically relied on Plateau, Beaver and House creeks for spawning areas, but the dam and reservoir altered the river so suckers cannot reach those ephemeral streams. In 2016, 4316 bluehead fingerlings were released downstream of the Dove Creek Pump house. In 2013, a pit-tag array recorded one flannelmouth traveled 264 miles.
The Montezuma Valley Irrigation Co. on Tuesday retreated from its boating ban at Narraguinnep Reservoir and agreed to allow some hand-launched, non-motorized watercraft.
The revised ban still includes motorized and trailered boats, including jet skis. Such watercraft can carry water from infected lakes in the engines, bilges and ballasts, according to the MVIC.
The specific list of nine non-motorized boats that are allowed on the lake include kayaks, canoes, rafts, belly boats, windsurfer boards, sailboards, float tubes, inner tubes and paddle boards.
“The board is in agreement on allowing those crafts,” Gerald Koppenhafer, president of the MVIC board, said on Tuesday.
Totten Lake, which is owned by the Dolores Water Conservancy District, also recently banned boating, but is also expected to allow the specific list of non-motorized boats, general manager Mike Preston said on Tuesday.
“The intention of our board is to be consistent with MVI and allow the exempted watercraft,” he said…
The boating ban triggered an outcry from the boating community, and generated complaints to the Montezuma county commission. Dozens of comments for and against the policy were posted on The Journal’s Facebook page.
McPhee Reservoir allows all types of boating, but trailered and motorized watercraft can only enter the lake through two boat inspection stations at the McPhee boat ramp and the House Creek boat ramp. The list of nine, hand-launched boats can launch from anywhere. Funding is available for boat inspection stations at McPhee but not other area lakes.
Irrigation companies and lake managers are trying to prevent the invasive mussel from entering Colorado waterways. Once a lake becomes contaminated with the mussels, they cannot be eliminated and cause damage to irrigation infrastructure, including dams, municipal systems and power plants. Mitigating a mussel contamination year-to-year also dramatically increases operation costs.
A decision is pending on how to prevent a mussel contamination at Groundhog Reservoir, which also is owned by MVIC.
The Dolores Water Conservancy District board voted unanimously on Thursday to close Totten Lake to all boating to prevent contamination by non-native quagga and zebra mussels…
The Totten closure follows a boating ban on Narraguinnep Reservoir, enacted last week by the privately owned Montezuma Valley Irrigation Co., which also cited the mussel threat.
“To prevent a mussel contamination, and to be consistent with MVIC’s decision, the board voted to prohibit all boating on Totten,” said DWCD general manager Mike Preston.
The boating ban on the two lakes is for all non-motorized and motorized, and includes kayaks, canoes, stand-up boards, windsurfers, oar boats, rafts and jet-skis. Fishing at the popular lake will be allowed from the shore.
“There was a lot of debate on our board about possible exceptions, but the board decided that to be clear, and best protect our irrigators, the ban will be to all boating,” said MVIC manager Brandon Johnson.
A boating closure order for Totten is being drawn up in cooperation with the Colorado Parks and Wildlife, which manages the fishery. A locked gate on the boat ramp will be installed soon. Narraguinnep already has a locked gate installed. Violators at Totten and Narraguinnep will be issued tickets by Parks and Wildlife and the Montezuma County Sheriff’s Office.
Boat inspection stations are effective at preventing a mussel contamination in lakes. But there is no funding for inspection stations at Totten or Narraguinnep, so managers say their only other option is to close them to boating because the contamination risk is too great.
The Dolores Water Conservancy District is also tightening up boating access on McPhee this year to better prevent the mussels from entering the regional irrigation reservoir.
Boating is still allowed at McPhee because there is funding for boat inspections. But access for motorized and trailered watercraft is only allowed during the season through two boat inspection stations at the McPhee and House Creek boat ramps.
When the stations are closed, newly installed locked gates will prevent lake access. In the past, boats could still launch when the inspection stations were closed.
To accommodate boaters who return to the ramps after the boat stations are locked, one-way spike strips will be installed this season to allow boaters to exit the lake after hours.
“We made that concession to prevent boaters from becoming stranded on the lake,” said McPhee engineer Ken Curtis.
McPhee managers adopted the state standard for preventing the mussel that requires trailered and motorized boats to be inspected, but allows non-motorized, hand-launched craft to enter the lake anywhere without inspection.
In general, non-motorized kayaks, canoes, rowboats, stand-up boards, and windsurfers pose less of a risk or contaminating a waterway with mussels.
However, mussels on a boat from an infected lake can be transported to another waterway.
All boats and their motors should be cleaned, drained and dried before entering a waterway and after leaving a waterway.
MVIC also owns Groundhog Reservoir, and is considering closing it to boating. A decision is expected soon.
The permanent boating ban went into effect Tuesday, said Brandon Johnson, general manager of the Montezuma Valley Irrigation Co., which owns the reservoir.
“We can’t afford to get the mussel in there because of the damage they cause to our infrastructure,” he said. “We had to take drastic action against this threat because we’re in the irrigation business, not the recreation business.”
Mussels from infected lakes, including Lake Powell, can travel in standing water of boats and contaminate other lakes, clogging pipes, valves and canals.
“If they get in there, we can’t deliver water to our stockholders, costs will increase to mitigate them, and they will get into side rolls and pipes,” Johnson said.
The Narraguinnep ban is for all boats, motorized and non-motorized, and includes jet skis, fishing boats, row boats, kayaks and canoes. Colorado Parks and Wildlife would enforce the ban and issue tickets.
Whether paddle boards and windsurfing would be allowed is not clear. “The board decided on a boating ban,” Johnson said. “Whether those two are boats is up to the enforcement agencies.”
MVIC also owns Groundhog Reservoir and is evaluating whether it will close that lake to boating, Johnson said.
Boating could possibly continue at Narraguinnep if there were a boat inspection program, he said, but the irrigation company cannot afford it.
“Recreation is the responsibility of Colorado Parks and Wildlife,” Johnson said.
Parks and Wildlife operates local boat inspection programs, including for McPhee Reservoir, to check for the mussel and decontaminate boats.
But CPW spokesman Joe Lewandowski said the agency does not have the funding to add more boat inspection programs.
“We’re scrambling for funding for the lakes where we do have inspection stations. They are costly to operate,” he said…
McPhee Reservoir is also restricting access to the lake beginning this year to prevent a mussel contamination. Boat ramps at McPhee and House Creek will be gated, and trailered boats can launch only when boat inspection stations are open.
The McPhee boating restriction does not include hand-launched, non-motorized boats such as canoes, kayaks, rafts, windsurfers and paddle boards. Non-motorized, hand-launched boats are free to launch anytime from anywhere on McPhee. However, all boat owners should make sure to clean, drain and dry all boats before and after entering any waterway to avoid invasive species contamination.
The most probable runoff forecast shows inflow of 440,000 acre-feet for April through July, enough to fill McPhee Reservoir and provide more than a three-month rafting release below the dam.
“Operations this spring are lining up to be exciting,” said Ken Curtis, an engineer with the Dolores Water Conservancy District. “The March forecast is typically not as accurate as the forecast that will come later, but it is good as a planning tool.”
The predicted runoff will fill the reservoir for farmers, with 270,000 acre feet potentially available for whitewater release below the dam. That is enough for an estimated 116-day boating season for approximately 100 miles between the Bradfield Bridge and Bedrock.
By comparison, in 2016, only about 30,000 acre-feet was available for a whitewater release below McPhee Dam, which generated about 10 days of boating flows.
Should the current forecast hold, operators will be able to provide releases of 800 cubic feet per second (cfs) and greater for about 67 days, with flows greater than 2,000 cfs for 45 days, and peak flows of 4,000 cfs for four days. Several ecological benefits also will be realized from a release of that magnitude.
The data in the March 1 operating plan is provisional and subject to change because of Dolores River inflow, future precipitation, weather patterns, managed release criteria and use.
The Dolores Water Conservancy District will be the primary source of information pertaining to release schedules and updates this spring. It will have a newly remodeled website at doloreswater.com.
Last year, the whitewater release lasted about 10 days and only peaked at 1,000 cfs. Before that, there had not been a release since 2011 because of drought conditions and low snowpack.
The main Lower Dolores River boating run stretches for 100 miles through winding, red-rock canyons interspersed with rapids ranging from Class I to Class IV. It is considered one of the premiere multiday boat trips in the nation when it has enough water to run. No permit is required.
The livestock association held its annual meeting at the Cortez Elks Lodge. Local, state and federal officials also spoke at the event, including U.S. Rep. Scott Tipton.
[Ken Curtis] said there is about 300,000 acre-feet of water in the snowpack for the McPhee Reservoir basin. However, but the reservoir will only be able to store about 90,000 additional acre-feet, he said.
“We’re going to get a chance to do a lot of active management,” Curtis said.
With water levels looking good, a recreation spill downriver is likely, but it’s still early, he said. Water officials will have to work hard to manage the above-average snowpack levels this season, he said.
Curtis also discussed the issue of mussels in waterways. The invasive quagga and zebra mussels have infiltrated the Great Lakes and are slowly making their way across the West, he said. Colorado has avoided an infestation, but they have appeared as close as Lake Powell, he said.
If mussels get into waterways on the Western Slope, they could cause costly damage to water infrastructure, such as dams and irrigation equipment, Curtis said.
Recreational boat inspections have been taking place on McPhee Reservoir and House Creek, but funding has decreased for inspections in recent years, he said. Hopefully funding will stabilize soon for the inspections, Curtis said, but in the meantime, access may be limited to recreational areas in 2017.
“We need to raise the insurance one level higher,” Curtis said. “We’re going to close lake access when the inspections aren’t happening.”
McPhee should be open seven days a week, but House Creek will probably only be open four days a week, he said.
Montezuma Valley Irrigation Co., which owns Narraguinnep and Groundhog reservoirs, has also considered closing boat access to both those lakes because of the mussel risk.
The U.S. Forest Service, Bureau of Land Management, Bureau of Reclamation and Dolores Water Conservancy District are raising money to continue boat inspections at McPhee and House Creek, he said.
The boat inspection program costs about $95,000 per year, and the Forest Service previously covered that cost, Curtis said.
No mussels have been found on boats during inspections at McPhee, but they have been found as close as Blue Mesa and Navajo reservoirs, Curtis said.
“Climate Change and the Upper Dolores Watershed, a Cold Water Fishery Adaptive Management Strategy,” is an extensive three-year analysis done in cooperation with the Mountain Studies Institute in Silverton.
The study used 72 climate models to tease out potential impacts to 46 trout streams in the basin from the town of Dolores to Lizard Head Pass up to the year 2100.
“We know there will be change, the question the study addresses is what kind of change can we expect, the approximate timing, and what are the impacts,” said Duncan Rose, director of the Dolores River Anglers chapter of Trout Unlimited.
When climate scientists ran the models over time, they pointed toward a “feast and famine” scenario, where wet periods with higher temperatures are followed by longer, more intense droughts.
According to the study, between 1949 and 2012, the upper Dolores watershed experienced wet periods with increasingly higher temperatures, followed by dry periods that were longer and more intense.
“We see that pattern developing where each drought gets more intense, and the wetter periods have higher temperatures, which causes increased evaporation and overall net loss of moisture,” Rose said.
If cyclical drought conditions were like 2002, the worst in recent years, and lasted for many years, the result could mean an average of 44 percent reduction in stream flows throughout the upper basin in 50-70 years, according to the study. Low stream flows contribute to higher water temperatures, which if reach above 63 degrees, are detrimental to trout species.
“Trout have survived these cycles for millennia, but the climate conditions may be more intense than what we have seen, so we’re going to have more challenges, particularly on the lower elevation streams,” Rose said.
The study is intended to aid current and future managers of Colorado Parks and Wildlife and the San Juan National Forest in sustaining good trout habitat in the basin.
For example, higher elevation streams will be less impacted by the climate predictions. Lower trout streams may be more or less a lost cause, with many perennial streams potentially becoming intermittent or drying up completely.
“That leaves the middle elevation band of streams, where mitigation and stream rehabilitation will do the most good,” Rose said. “It’s an adaptive management model, where we don’t rush in, take it a step at a time and invest limited resources with what climate pattern emerges.”
Protecting trout streams from higher temperatures and lower flows means improving shade, installing instream rocks and trees to create pools where fish can find refuge in lower flows and hot conditions. Streams like Roaring Fork, Scotch Creek, Kilpacker, Burnett, and higher-up stretches of the Dolores Main stem, plus others, would likely benefit the most from habitat improvement in the future.
More regulations may by on the horizon, as a result of the study’s projections, for example, lower bag limits, catch-and-release only rules, barbless hooks, and even rotating some streams into non-fishing status for a year to allow recovery.
The climate models indicate there will likely be a reduction in the 295 miles of trout streams in the upper Dolores Basin in the next 50 to 100 years. More of the fishing spots will be concentrated in the higher elevations, which would result in more people fishing in a smaller area.
“There will be more competition for fewer fish, but the good news it will not happen overnight,” Rose said. “We have time to adapt, as long as we are aware of the potential impacts.”
This summer, the Dolores chapter of Trout Unlimited will be installing eight temperature gages on various streams and rivers at different elevations to start monitoring changes and trends.
The Dolores River climate change study cost about $20,000 with $15,000 paid for by the Colorado Water Conservation Board. Other groups, including TU, Southwestern Water Conservation District and the Montezuma Land Conservancy contributed funds as well.
Board President John Porter and Vice President Steve Fearn, representatives of Montezuma and San Juan counties, respectively, were voted off the board by commissioners in their respective counties.
Fearn, a prominent longtime coordinator of the Animas River Stakeholders Group, has represented San Juan County on the water conservation board since 1990 and served as vice president since 2007.
But San Juan County commissioners said Fearn’s representation no longer reflects county values, which have changed significantly since Silverton’s mining days to include more recreational interests with respect to water, county attorney Paul Sunderland said…
Commissioners voted to appoint Charlie Smith, part-time Silverton resident and eight-year general manager of the Lake Durango Water Authority, as Fearn’s replacement.
“Commissioners thought Charlie Smith would better represent San Juan County,” Sunderland said. “He has a lot of water expertise, and he’s probably more in tune with the wants of the current board. Historically, San Juan County has been largely dominated by mining interests, and Steve Fearn is very much associated with those interests, but the board’s interests have shifted more toward recreation.”
The fact that the state of New Mexico named Fearn in a lawsuit as a “potentially responsible party” for mine pollution in the Gladstone area was noted in the county’s decision, Sunderland said.
“It’s definitely something we’re aware of, given his ownership interests around Gladstone,” he said…
The board consists of nine members representing Archuleta, Dolores, Hinsdale, La Plata, Mineral, Montezuma, Montrose, San Juan and San Miguel counties. Board directors can serve an unlimited number of three-year terms.
“I want to make sure the county’s views are represented,” Smith told The Durango Herald. “I have an understanding of their water rights, and a lot of work needs to be done to secure those rights and make sure the uses align with what the county envisions.”
Montezuma County commissioners selected Don Schwindt to replace Porter, who was general manager of the Dolores Water Conservancy District for 22 years and a Southwestern board director for 26.
Schwindt is a director on the Dolores Water Conservancy District board and a critic of the Dolores National Conservation Area, a controversial proposal in Montezuma County to congressionally protect land and water along the lower Dolores…
Porter thinks the proposal, criticized by Montezuma County commissioners, influenced his removal. Under Porter’s leadership, Southwestern Water Conservation District contributed funds to hire a water attorney to rewrite draft National Conservation Area legislation, which Porter thinks was perceived as support for the bill.
“I perceived the funding as an effort so everyone involved knew all the problems, the facts on both sides and could intelligently make a decision,” Porter said. “I think Southwestern’s involvement was perceived by others that we were very much in favor of the NCA legislation. That had something to do with it, and the fact that I’m 80-plus, and my 26 years on the board.”
Montezuma County Commissioner Larry Suckla said the commission chose Schwindt because of his water knowledge, and the conservation area proposal did not play a part in the decision.
“Don has shown ways that he would save water and retain water for farmers and ranchers,” Suckla said. “John Porter is an icon for Montezuma County. He was involved in the management of the lake (McPhee Reservoir), and all the benefits the county has received from that is because of the work he did, but it felt like it was time for new eyes.”
When Porter joined the board in 1990, he said water storage and dam construction were the district’s primary focus, including such projects as Lake Nighthorse. But gradually, the focus broadened to consider recreational water use and water quality.
Porter refers to his tenure as a career highlight, and said the importance of inter-basin relations and dialogue will only increase as time goes on, water supply dwindles and population grows.
“You’re asking someone who’s biased, but I’ve always felt that the Southwestern board tried its very best to represent all interests,” Porter said. “True, the majority of the members, including myself, were and still are agriculture-oriented. Yet to me, as Colorado’s population grows, it’s inevitable that our water supply will be drying up agriculture. And that’s not in our best interest, but I don’t see a way of satisfying municipal needs that we’re going to have without drying up some ag use. Irrigation takes a lot of water, and just that amount converted to municipal use will take care of a lot of families in an urban situation.”
Local apples were once again pressed into juice for market during a successful pilot project held in a Lebanon orchard last month.
The event, sponsored by the Montezuma Orchard Restoration Project, processed 800 bushels of apples gathered from local orchards.
“It went really well, we generated 2,200 gallons of raw juice that was sold to hard cider makers,” said MORP manager Nina Williams.
The group is studying the feasibility of using a mobile pressing unit to process apples from the many forgotten local orchards that otherwise let the fruit go to waste.
They were awarded a $42,400 planning grant from the U.S. Department of Agriculture to test the idea.
For two days in October, Northwest Mobile Juicing, out of Montana, set up in the Russell apple orchard in Lebanon. The unit can press, pasteurize, and package the juice for market.
For the pilot, the raw juice could only be sold to hard cider companies for fermentation. Additional permits are needed to sell pasteurized apple juice.
“We proved we can get if off the trees for sale to the hard cider market,” Williams said. “If the demand is there we can work through the regulations to sell local juice as well.”
Several orchard owners realized some profits from the project, and were paid 10 cents per pound for apples still on the tree.
A dedicated crew of twenty MORP volunteers spend 300 hours picking the apples in the weeks prior to the pressing. In all, nine apple orchard owners were paid $3,500 for their apples.
One local cider maker and four from Boulder and Denver bought the raw juice. A semi-truck was loaded with the juice for a night run to Front Range cideries.
“They were impressed with the quality,” Williams said. “The juice was a blend of local heritage apple varieties.”
Apple mash produced was hauled off by local livestock owners for feed.
MORP said they broke even on the trial run, and are studying how best to set up a local pressing facility.
“We learned that there is a lot of labor and infrastructure involved besides just the pressing equipment,” Williams said.
Commercial apple operations require warehouses, shipping docks, refrigerated cold storage to store apples, and heavy equipment such as trucks and forklifts.
MORP has been documenting once popular heritage apple varieties from the days when the area was a thriving fruit market more than 100 years ago.
They have brought many of them back to life through careful grafting and propagation techniques, and are encouraging local farmers to plant heritage apple orchards.
“Our big goals is to bring back this genetic diversity to keep heritage apples from going extinct, and to get it so people can have these trees again,” said MORP orchardist Jude Schuenemeyer. “Trees that worked here for over 100 years are really well adapted to this place.”
A recent victory for MORP was the rediscovery of the rare Colorado orange apple in a Cañon City orchard in 2012. For the last several years, local orchardists have been grafting and cultivating this near-extinct apple known for its fine flavor, hardiness, storage qualities, and cider-making potential.
There are dozens of abandoned apple orchards in the county that still produce a good crop, but have a limited market. The juice market is seen as ideal because the apples do not have to be perfect and the ones that fall on the ground can be used as well.
“One of our goals is to get local orchards back in shape by hosting workshops this winter on pruning and orchard management,” Williams said.
The call was initiated to satisfy in-stream flow rights below McPhee Dam of 78 cubic feet per second, but local water managers say the water will never get there.
In-stream flow rights are administered by the water board to preserve the natural environment in state rivers to a reasonable degree. They are a priority water right senior to some, but junior to others.
A call is made to maintain a water right’s priority in the Colorado system of prior appropriation, commonly referred to as “first in line, first in right.”
Because of the call initiated this month, a man-made ditch diverting water from Little Fish creek and Clear creek to Groundhog was shut off, allowing the creeks to flow naturally into the Dolores River via the West Fork.
Marty Robbins, District 32 water commissioner for the Department of Natural Resources, said the call caused water administrators to enforce Groundhog’s one-time fill system that legally allows the reservoir to only fill from Nov. 1 to May 1. Groundhog Reservoir, owned by the Montezuma Valley Irrigation Co., typically diverts the streams into the reservoir year-round.
“Just because it has been done before, does not mean it can when there is a call,” Robbins said. “These calls may happen more regularly.”
On Nov. 1, the reservoir will go back on priority for filling, and the diversion ditch will be reopened, officials said.
The administrative call sends the creek water into the upper Dolores River and McPhee Reservoir, managed by the Dolores Water Conservancy District.
But Dolores Water Conservation District general manager Mike Preston says the extra water will stay in the reservoir and not flow through the dam to the lower Dolores River.
“McPhee’s water rights are senior to that in-stream flow right, and we have a storage right that allows for refill,” he said.
The in-stream flow water right on the Lower Dolores River is intended to preserve habitat for native fish, including the round-tail chub, bluehead sucker, and flannelmouth sucker. Federal and state biologists have reported that an increase in flows below the dam is needed to improve native fish habitat.
But the unexpected call by the state for delivery of in-stream water rights had an unintended consequence of threatening trout elsewhere, said Montezuma County Commissioner Larry Don Suckla.
The diversion ditch from Clear Creek to Groundhog Reservoir supports trout population, he said, but they became doomed when the water was cut off.
“Explain to me how water can be diverted for native fish, but is allowed to hurt trout?” he said.
Brandon Johnson, manager for the Montezuma Valley Irrigation Co., said the Colorado Water Conservation Board’s administrative “call presents issues at Groundhog we were not anticipating.”
The Colorado Water Conservation Board also made administrative calls for in-stream flows rights on other rivers in the state to establish that the rights exist and to reveal if any water users are out of priority, officials said. The calls were made after irrigation season so they would be the least disruptive.
The additional water flowing into McPhee as a result of the call will be divided among allocation holders in 2017, Dolores Water Conservation District officials said.
A plan is being considered by local, state and federal agencies to close the McPhee and House Creek boat ramps with locked gates during times when boat inspectors are absent. The new management strategy would go into effect in 2017.
Currently, there are no gates at the boat ramps, and trailered boats can launch after hours when boat inspection stations are unattended.
“It is important to fill the inspection gaps, because the problems and expense of mussel contamination are severe,” said Mike Preston, general manager of the Dolores Water Conservancy District, which manages irrigation at McPhee reservoir…
Their presence causes damage and vastly increases maintenance costs long-term. They negatively impact the lake’s sport fishery by filtering the water and competing for food.
McPhee is considered an at-risk lake for the mussels because of its proximity to Lake Powell and Lake Mead, both of which are heavily contaminated with the mussel…
Locals know about the problem, and understand the importance of draining and drying their boats, Preston said.
“The worry is a visitor arrives with an infected boat that slips through. It just takes one,” he said.
DWCD, the Bureau of Reclamation, San Juan National Forest, and Colorado Parks and Wildlife signed a memorandum last week to share long-term costs and management for the proposal to improve the McPhee boat inspection program. The program currently costs $85,000 per year to run.
McPhee’s two boat inspection stations typically analyze between 8,000 and 12,000 trailered boats per year since 2009, and the numbers have increased in the past two years.
This year at McPhee, the number of boats needing decontamination went up 40 percent, managers said.
The new plan would limit access for the public such as for boaters wanting to put on early in the morning, or late evening, before and after the boat inspection stations are open. Access during shoulder seasons would also be reduced because inspections stations are open less.
A sporadic 12-day boating release from McPhee dam into the Dolores River in June was hampered by uncertain runoff forecasts after a late-season snowfall, reservoir managers said at community meeting Tuesday in Dolores.
Boaters faced on-again, off-again announcements of whitewater releases from the dam, which complicated their plans for trips down the river. It was the dam’s first whitewater release since 2011.
A 22-day rafting season was forecast as possible in March when snowpack registered at 130 percent of its median normal. A two-month dry spell erased the advantage, and the release was adjusted to five to 10 days of boating for late May. The forecast then dropped to a three-day release in early June, and after it was confirmed days later, hundreds of boaters flocked to the Dolores as it filled below the dam.
“Small spills are the most difficult and tricky to manage,” said Mike Preston, general manager of the Dolores Water Conservancy District, which manages the reservoir.
But on the fourth day, managers said they realized the volume of river inflow was more than the reservoir could handle, and the dam release was extended nine additional days.
“The second spill was highly under-utilized,” said boater Kent Ford, who added that the lack of notice “killed a lot of multi-day trips.”
Vern Harrell, of the Bureau of Reclamation’s office in Cortez, attributed the uncertainty to the narrow margin of runoff expected to exceed reservoir capacity.
The runoff forecast has a margin of error of 10 percent, “and this year, the spill was within that 10 percent,” Harrell said.
Decisions about dam releases rely on forecasts from the Colorado River Basin Forecast Center, which depends on Snotels that measure snowpack in the Dolores Basin.
When there is possibility for a small spill, managers don’t have the tools to give a lot of notice, Harrell said, so decisions are made day-to-day based on river inflow and reservoir levels.
“By May, all the Snotels are melted out, and we are in the blind,” he said.
In small spill years, managers said they err on the side of caution when announcing the number of days available for boaters. They want to ensure that the reservoir remains full, but they don’t want to end a dam release prematurely.
“We have to be careful we don’t leave boaters stranded on the river,” Harrell said.
Ken Curtis, an engineer with Dolores Water Conservancy District, said the priority is to fill the reservoir, and if there is excess water, it is managed for a boating release.
It was especially difficult to forecast runoff into the reservoir this year, he said, because much of the late-season precipitation came as rainfall.
“In May, we called off the spill because we were not reaching our reservoir elevation,” he said. “Then the forecasters bumped us up by 30,000 acre-feet,” enough for a small spill.
At the end of a five-day release, the forecast center showed a dip in river inflow, “so we started to shut the gates, but the river inflow was hanging in there,” and the spill was extended several days.
Managers acknowledged that they were rusty managing the release. They’d faced many dry winters that hadn’t filled the reservoir, and the unusual winter of 2015-16 complicated the matter.
Sam Carter, president of the Dolores River Boating Advocates, said boaters and the reservoir managers cooperate on potential spills, and this year was a learning experience.
Overgrown banks, loads of sediment in the waterway and a depleted fishery cast a pale backdrop to an otherwise awe-inspiring float down the lower Dolores River, known for its deep canyons, lush ponderosa forests and seemingly endless succession of whitewater.
“And all of that is just a reflection of the channel starting to reflect the current hydrology,” said Colorado Parks and Wildlife aquatic biologist Jim White. “It has changed.”
Today, water out of McPhee Reservoir, considered the most expensive allotments in the Southwest, mainly supplies farms growing alfalfa, one of the most water-intensive crops used to feed cattle.
The divisive interests between farmers and recreationists have caused a debate over water rights to rage on for almost four decades.
A different riverSince the dam operates on a “fill, then spill” policy, enough water to float the lower Dolores River is only released when the dam is at capacity, and there’s no other place to store inflows.
That hadn’t happened since 2011 – until this year, when two small releases allowed boaters as well as wildlife officials to get an inside peek at what’s been happening to the long-neglected stretch of river.
And it didn’t look good.
The wildlife division’s White said a survey of the 19-mile stretch from Bradfield Bridge to the Dove Creek Pump Station found only 150 brown trout, a non-native species, and came up nearly empty-handed on native species.
“The loss of consistent spring flow to maintain habitat, coupled with altered base flow regimes, just all adds up to where we’re seeing reduced numbers of native species,” White said. “But what struck me, just the abundance of fish in general, native and non-native, is low through that part of the canyon.”
Another discernable transformation noted by many boaters was the unbridled vegetation that has started to bottleneck the river’s original channel. It was one of the most striking changes Sam Carter, board president of the Dolores River Boating Advocates, noticed on his trip this year.
“The overgrowth was intense, and dangerous,” Carter said. “There were two places that made it dangerous to move in a rapid.”
Carter said for the most part, this year’s release was a success: The large turnout of Dolores River aficionados worked together at boat launches, the weather made for hot days and warm nights, and the past year’s lack of access to the river left campgrounds, and the canyon in general, as wild as ever.
Yet a larger issues looms.
“This one spill is not the answer,” Carter said. “There has to be a change in the paradigm how that water is used. The river is getting killed. It’s a slow process, but it is happening.”
Is change possible?Mike Preston, general manager of the Dolores River Water Conservancy District, said at this point, it is “highly, highly unlikely” that any changes would occur to the management plan for the Dolores River.
Preston, a boater himself who took a trip on the Dolores River this year, said many farmers in the area made large investments setting farms up based on the water allocations.
“One boating day at 1,000 cubic feet per second is enough water to irrigate 1,000 acres for a full season,” he said. “And the farmers are paying us to maintain the facilities. And they also make payments to the federal government.”
Indeed, John Porter, a farmer turned Dolores Water Conservancy District manager who retired in 2002, said he’s clear in his bias for use of the river.
“There’s another side of it,” Porter said. “Do you just quit farming in this area and leave the water in the river? Until McPhee, it was dry river in the summertime because all the water was diverted. This project at least keeps it as a full-time river.”
Though the Dolores flowed anywhere from 800 to 1,500 cfs during the release, river levels throughout the year remain chronically low. In 2013, for instance, the river was at a trickle at just 13 cfs. The boating advocate’s president Carter said that doesn’t exactly constitute a healthy, flourishing river.
Carter said the group is “very actively” working on ways to secure annual releases out of McPhee for the benefit of recreationists and the environment.
“It’s not going to happen overnight, but we’re definitely working on it,” Carter said.
But for now, as the Dolores River slowly returns to its dispossessed flows, boaters look with a mixture of frustration and optimism toward next year.
“It was very much a bigger adventure than I think most people anticipated,” said Josh Munson, a board member of the Dolores River Boating Advocates. “Many longtime boaters noted the same things. It was faster, more wild. But the lack of water is really changing the characteristic of the river itself.
“When there isn’t a recreational release, it really isn’t much of a river.”
Over the weekend, hundreds of boaters took advantage of a three-day whitewater release on the Dolores River below McPhee dam, the first in four years.
Reservoir managers said Sunday, the minimum rafting flows will continue until at least Tuesday, June 7.
The weekend whitewater release was announced last week on short notice, and within hours, the boat ramps at Bradfield Bridge and Dove Creek Pumphouse began filling up local boaters and their brightly colored rafts, kayaks, canoes and dories…
Friday morning, a parade of boats disappeared into the sunny Ponderosa Gorge, the first leg of 97-mile stretch to Slick Rock that features rapids, camp spots, remote hiking and spectacular scenery.
Bears roamed the shorelines and campsites, and were startled by the sudden presence of humans. River otters swam among boaters, and desert big horn sheep looked on from above.
A new rock fall in the river at mile-marker 17.2 can be skirted river left.
Reservoir managers have announced a 10-day spill at an approximate rate of 1,000 cubic feet per second. However the plan is to begin the release the first weekend of June instead of over Memorial Day as forecasted last week.
“There will be a spill, and by pushing it forward we’re setting up the boaters for a longer season with improved rafting flows,” said Mike Preston, manager for the Dolores Water Conservancy District.
Warmer weather beyond the current five-day forecast could accelerate the start of the spill by a few days.
McPhee will fill and provide full farmer allocations, with an estimated left-over water for rafting.
Cooler, stormy weather and significant snowpack holding in the mountains forced managers to adjust the timing of the spill until the first weekend of June.
Reservoir managers are waiting on a second peak runoff from remaining snowpack.
Preston said the decision for the delay is to avoid the possibility two small spills and their associated ramp-up and ramp-down water needs. For safety, spills are gradually increased 200 cfs at a time, then reversed at the end of the controlled spill.
Releasing rafting flows for Memorial Day weekend was not seen as ideal for boaters because managers would have to stop it to allow the reservoir to fill. Then a second spill would likely be required to avoid overfilling the reservoir as the second peak finishes coming down.
“Delaying for one release saves ramping water to extend the season,” Preston said.
The benefits of a single combined spill of rafting flows allows for longer trips and less down-river congestion of boaters.
The district worked closely with the Dolores River Boating Advocates on the early June release decision.
“There has been definite improvement in communication between the reservoir managers and the boating community,” said DRBA board member Wade Hanson. “DWCD and the Bureau of Reclamation have been on the ball with timely public notice about a release.”
Boaters should be aware of some new changes on the Lower Dolores River.
The usual private land available for a public take-out/put-in at Slickrock is closed.
However, another landowner is negotiating with the DRBA to open public access point on land just downstream of the bridge at Slick Rock near the old store.
Farther down river, the BLM’s Big Gypsum Valley river access remains open.
Boaters should be especially alert this season on the Lower Dolores because it has not been floated for many years.
A large boulder fall has been reported in Ponderosa Gorge upstream of the Dove Creek pump house at mile 17, and debris flows and log jams are a real possibility.
Also expect campsites throughout the 100-mile section to Bedrock to be overgrown.
“It’s exciting to get on the Lower Dolores after all these years,” said Hanson said. “We will be taking a lot of pictures and GPS coordinates of the campsites to inform the public.”
The Dolores Water Conservancy District announced on its website on Monday that recent heavy precipitation, including what’s in the forecast for this week, would likely fill McPhee Reservoir and allow for a boating release. If it happens, it would be the first since 2011.
The water district said that the precipitation combined with a cool, slow start to irrigation season has left the reservoir just 12 feet below full.
“A boating release will likely cover the Memorial Day weekend and last 5-10 days at 1,000 +/- CFS (cubic feet per second),” the website says.
The district says it will continue to keep boaters updated through the week.
The Dolores River was dammed in the late 1980s, which created McPhee Reservoir to ensure domestic water supply for Cortez and the Ute Mountain Ute Tribe, and irrigation for more than 70,000 acres of otherwise arid land.
Five automated, high-tech pumping stations do the heavy lifting of pulling water from canals and pushing it through pipes to farms. Another pump system at the Great Cut Dike pulls water from McPhee Reservoir into the Dove Creek Canal and onto the pumping stations.
The Dolores Water Conservancy District and the Bureau of Reclamation have teamed up for $8 million worth of upgrades for the 20-year-old pumping stations.
The four-year plan includes upgrading the electronic communication control system, or SCADA, which operates irrigation deliveries from a main control room.
So far, three out of six pumping plants have been overhauled: Fairview, Pleasant View and Ruin Canyon. Next on the list are Dove Creek, Cahone, the Great Cut Dike and the SCADA system. Final upgrades will begin after irrigation seasons and be completed over the next two years.
Water officials and engineers touted the upgrades during a public tour Thursday at the Pleasant View pump station. At Ruin Canyon, two pumps were rebuilt, and two variable-speed electric motors were replaced. The electronic drive systems were also replaced.
The same upgrade occurred at the Ruin Canyon pump station, with a total cost for both upgrades of $1.25 million.
“They are more efficient, run cooler and require less maintenance,” said DWCD engineer Lloyd Johnson. “They will last another 20 to 25 years.”
The variable speed pumps adjust to irrigation demand. As the pressure fluctuates, the electronic drive system directs the pumps to adjust and keep the pressure steady. The drive system automatically turns on other static pumps as demand requires.
“We’re here to meet demand of the farmer,” said engineer Ken Curtis. “They pay high dollar for volume when they want it, and that is why we have a big crew of electricians and mechanics to ensure it is all working.”
The Bureau of Reclamation built the dams and reservoirs and pays to update them, said Brent Rhees, BOR’s regional director for the Upper Colorado River region.
He explained that a portion of power revenues generated from Glen Canyon dam and other BOR hydro-electric plants are set aside to pay for project upgrades like the one at the Dolores Project.
“These upgrades are satisfying to see because they keep us grounded in our mission to deliver water,” Rheese said. “The BOR has transitioned to resource management of existing projects.”
A documentary screening about the Dolores River was followed by a lively forum about the issue of low flows below McPhee Dam.
“River of Sorrows” was commissioned by the Dolores River Boating Advocates to highlight the plight of the Lower Dolores River.
The new film, which is for sale on the DRBA website for $10, had several showings April 30 at the Sunflower Theatre.
A panel answered questions from a moderator and from the audience. The panel included Josh Munson of the DRBA; Mike Preston, general manager of the Dolores Water Conservancy District; Eric White of the Ute Mountain Farm and Ranch; Mike Japhet, a retired aquatic biologist with the Colorado Parks and Wildlife; and Amber Clark, of the Dolores River Dialogue.
What are the major challenges facing the Dolores River and what are the solutions for addressing those challenges?
Munson said the challenge is for people to see there are beneficial uses to Dolores River water other than just farming, such as for fishery health and boating. Changing the water rights system to allow individuals to sell or lease their water allocation so it stays in the river is one solution.
“Other uses helps to diversify the economy,” he said.
Preston said a major challenge is managing the reservoir in drought conditions. He said the goal is maximizing efficiencies in order to improve carryover in the reservoir year to year.
“High storage lifts all boats, including for recreation,” he said.
White said the film missed the compromises the Ute Mountain Ute tribe has made regarding water rights.
“Our allocation has dropped,” he said. “The tribe has fought for our water rights for a long time.”
Japhet said low flows below the dam are threatening three native fish: the flannelhead sucker, bluehead sucker, and roundtail chub.
“They have been declining precipitously,” he said.
Japhet called for more flexibility in how water reserved for fish and wildlife is managed out of McPhee. For example, 850 acre-feet diverted to the Simon Draw wetlands could be used to augment low flows on the Lower Dolores to help fish.
Clark said the big picture solution need to be collaborative and local, “or somebody from outside will find a solution for us.”
The group revealed the difficulty in finding a compromise that improves the downstream fishery and recreation boating but does not threaten the local agricultural economy.
“Use if or lose it water doctrine is a waste of water resources for farmers and conservationists,” Munson said. “The system does not allow for an individual to lease their water” for instream purposes.
Preston pointed out that in the last eight years, there has been four years where there was a release from the dam. The last one was in 2011, and this year a spill is uncertain.
“We are four for four. When we have excess water we release for boating and the fishery,” he said.
Japhet said the “elephant in the room” is if one of the three native fish species is petitioned for listing on the endangered species list.
“It would cause the U.S. Fish and Wildlife to take a very close look at what is going on with the water and fish resource,” he said. “The best solution is to be proactive and work something out locally to avoid a federal mandate telling us what to do.”
An audience member asked if the river itself has a right to water. Preston said the state instream flow program designates minimum flows for the river, including a 900 cfs below the confluence with the San Miguel. Below the dam the instream flow designation is 78 cfs.
“The river has a right to water, the fact that it was once wild should stay in people’s minds,” Munson replied. “The place itself has a beneficial use for fish, birds, otters. It’s recreation provides a way to make a living.”
Betty Ann Kohlner expressed concerns about McPhee water being used for hydraulic fracturing used for drilling natural gas.
Preston said about 4,000 acre-feet is available in McPhee for municipal and industrial purposes, including for fracking. But, he said, There has been limited use of the water for that purpose.
“If you can lease water to frack, why can’t water be leased for recreation and fish needs downstream from willing owners?” responded one man. “There is a contradiction in how we apply our understanding of how we should use water.”
Don Schwindt, of the DWCD board, pointed out that the Dolores River is part of the Colorado River compact that divides the state’s river water with several downstream states.
“Two thirds of the state’s water is required to leave by compact, and as it leaves it is available in the streams,” he said. “That two-thirds is more dominate than agricultural use.”
I had the pleasure of viewing the new documentary “River of Sorrow” from the Dolores River Boating Associates yesterday at the eTown Hall in Boulder. The Colorado Water Trust hosted the event. River Network President Nicole Silk, CWT Executive Director Amy Beattie, and filmmaker Cody Perry introduced the film by detailing their personal experiences which led them to a life working with water.
In the film a farmer in Montezuma County detailed the necessity, from her point of view, for McPhee Reservoir. She acknowledged that she understood the motivation of those that want higher releases from the dam for recreation and the environment and the conflict it causes with the irrigators in the Montezuma Valley.
This is the main message: There are too many straws in the Dolores River, or as one person in the film, says, “Yeah, the Dolores River is very iconic, but it’s really a river no more.”
One of the highlights was the rare film footage of boatmen and enthusiasts from the heyday of boating in the years leading up to first fill. Even after first fill the boating survived until the diversion structures were built and started delivering water from the Dolores Project to the San Juan Basin.
The reservoir filled during a wet time and for a while there was a gold medal trout fishery below the dam. Then dryness hit the region (and is still around).
Now, organizations are attempting to reconcile competing views, learning that water rights are in control, and trying to find recreation and environmental water for the river.
Here’s a review from Dennis Webb writing for The Grand Junction Daily Sentinel:
A new documentary film on the Dolores River is to some degree a lament to a river lost, or at least transformed to a degree that it’s hardly recognizable to people with long memories.
“River of Sorrows: Inheriting Today’s Dolores River,” … documents the changes wrought on the river first by the construction of the dam at McPhee Reservoir near the town of Dolores in the 1980s, and then by drought.
While it’s a story about one waterway, it’s one that echoes in river canyons across the West that face challenges similar to the one on the Dolores when it comes to competing demands for scarce water supplies.
“You could say that the Dolores is the canary in the coal mine,” said filmmaker Cody Perry of Rig to Flip, a film production company based in Steamboat Springs. “You could say that the Dolores is potentially the future of every river in the Colorado River Basin in terms of if we have intentions to further develop every drop.”
The Dolores originates in the snowfields of the San Juan Mountains, heads southwest to Dolores and then north along the Colorado border to Gateway before crossing into Utah and its endpoint, the Colorado River.
Perry’s company contracted with the group Dolores River Boating Advocates to tell the river’s story, and particularly describe its life before and after McPhee Reservoir.
The reservoir project provided an important supply of water to agricultural users, as the film shows. But, except for in the wettest of years, it went far in decimating whitewater rafting on what was coming to be considered one of the nation’s best stretches of whitewater, below the reservoir. The river had been growing in renown for its rapids and pristine, slickrock-studded scenery.
For the first five years or so after the dam’s construction, the stretch below it did prove to be a prime trout fishery. But then drought hit, flows dropped below the dam to as little as 20 cubic feet per second, the water warmed and many fish died along the stretch of the river above its confluence with the San Miguel River in Montrose County.
The film quotes Montezuma County Commissioner Larry Don Suckla about the passions boaters, anglers, farmers and others feel regarding the river, and the fact that each group feels threatened.
“But in reality everybody owns that river,” Suckla said.
From the farmers’ perspective, the fear is that they will get less water if more water is released downstream for the fish, he said.
“All the water is already allocated. There is no extra water that is available to send down the river,” Suckla says.
“It’s going to be hard to get this fixed,” he adds later.
The comment succinctly sums up the challenge faced by water managers and the competing interests when it comes to the Dolores, which got its name from the Spanish “El Rio de Nuestra Señora de Dolores,” meaning “The River of Our Lady of Sorrows.”
For whitewater enthusiasts, the film’s high point also is bittersweet. The filmmakers developed contacts with river guides who dug up film footage from the old days of the Dolores when the rapids sometimes raged, including in 1983, the epic spring runoff year when Lake Powell almost overflowed.
Immediately after showing this footage, the film cuts to the lower Dolores today below the dam, barely trickling with water. An unnamed voice provides narration.
“Yeah, the Dolores River is very iconic, but it’s really a river no more. It needs to be seen and supported and it needs to be a river again,” says the voice, which Perry said is that of Andy Hutchinson, a famed Grand Canyon river guide who serves on the board of Dolores River Boating Advocates.
Perry said the archival footage is both thrilling and a reminder of what’s been lost.
“There’s generations of kids who have no idea about this river, and we don’t have that piece of whitewater anymore. It’s a cultural loss, and the generations of people who ran it — there’s a massive gap to today’s river runners who have no idea that was down there,” he said.
He said he’s shown the film to schools, groups of so-called “water buffaloes” and others. He said he was surprised that water managers in particular thought it does a good job of describing the players and issues at hand.
While the film is sympathetic to boating and environmental interests, he said some more extreme environmentalists wish it was edgier. But he feels the film’s job was to educate more than advocate.
“Seven of 10 people in Colorado have never heard about this river, let alone the issues that are specific to it yet also common to other rivers,” he said.
Perry said he’s concerned about the future of agriculture, too. His hope that in the case of the Dolores River, agricultural, recreational and other interests can be willing to show more flexibility in their discussions with each other, and that legal tools can be provided for permanent transfer or long-term leasing of agricultural water for instream flows.
The various interests “need to stop digging in their heels and we have to start meeting each other halfway,” he said.
Go see the film then take in the sights of Four Corners and see the country and the Dolores River for yourself.
McPhee Reservoir managers announced Friday that the forecast calls for a whitewater release below McPhee Dam.
“The forecast shows a 22-day whitewater season,” said Bureau of Reclamation engineer Vern Harrell. “But it is a 50-50 probability, so it is not guaranteed it will materialize.”
Based on this year’s impressive snowpack in the mountains, runoff forecasts show the reservoir will fill, and there will be 68,000 acre-feet available for a spill into the lower Dolores River.
Here is the plan if the snowpack holds:
On May 17, flows below the dam would be increased to 500 cubic feet per second. It would ramp up to 900 on May 18, then 1,300 cfs on May 19, and 1,500 cfs on May 20.
From May 21-25, the plan is to max out the flows at 2,000 cfs, then they will drop slightly to 1,800 cfs from May 26 to June 1 for the Memorial Day weekend.
On June 2 flows will be reduced to 1,400, cfs, drop 1,000 cfs on June 3, to 800 cfs on June 4 and 5, to 600 cfs on June 6 and 7, to 400 cfs for June 8 and 9, then 200 cfs for June 10 and 11.
Minimal rafting flows is 600-800 cfs, and for kayaks it is 300-400 cfs. Tubing could be done at 200 cfs.The boating community is excited, but cautious, said Josh Munson, vice president of the Dolores River Boating Advocates…
There has not been a whitewater release below the dam since 2011.
The surge of water into the lower canyon will benefit the natural environment, Munson said, and create an economic boon to the area as recreational boaters descend to the various launch sites.
Colorado has listed 105 miles of the Dolores River between Slick Rock and the Utah state line as an impaired waterway because of high water temperature from chronic low flows.
The Water Quality Control Commission of the Colorado Department of Health and Environment ruled on the river’s impairment status during a hearing in December.
The section on the Lower Dolores River is “considered impaired because the temperature was greater than standards adopted to protect aquatic life,” said Meghan Trubee, media relations official with the Colorado Water Quality Control Commission. “We’re mostly concerned about the fish and macro invertebrates.”
“Because the stream is listed as impaired, the division is responsible for developing a plan to address the temperature impairment known as total maximum daily load (TMDL),” Trubee said. “The segment will remain on the 303(d) list until a TMDL is developed and approved by the EPA.”
A year’s worth of temperature data from a water-quality station at Slick Rock showed the river went above the daily maximum temperature standard 10 times – five in September 2013 and five in June 2014.
The separate readings went above daily maximum standard for March to November of 28.6 Celsius, or 83 degrees Fahrenheit.
“Warmer water has less ability to hold dissolved oxygen, which fish need,” said Jim White, a fish biologist with Colorado Parks and Wildlife. “The other reason is that higher base flows in the summer would create more habitat for growing invertebrates, the food relied on by native fish.”
The impaired section is below McPhee dam and reservoir and has not had a recreational whitewater release since 2011.
Water allocated for fish habitat, about 31,796 acre-feet, is held in McPhee reservoir and released throughout every year. In the winter, flows below the dam are 20-30 cfs. During summer, they reach 60-80 cfs if there is no whitewater release.
A series of low snowpack years have left the reservoir below full and only able to supply irrigation demands. A whitewater release occurs when there is more runoff than the reservoir can hold.
The Dolores Water Conservancy objected to the lower Dolores impairment listing, but wasn’t successful
