FromThe Grand Junction Daily Sentinel (Dennis Webb):
A 2016 agreement is helping protect Colorado River flows downstream of Glenwood Canyon despite ice jams from the Colorado River shutting down the Shoshone Hydropower Plant in the canyon.
Jim Pokrandt, spokesman for the Colorado River District, a tax-funded agency serving counties within the river basin in western Colorado, said the problem at the plant occurred around March 1. Xcel Energy, the plant’s owner, says it won’t be using Colorado River water at the plant until it is repaired.
The plant’s operations are watched closely by the water community because it has one of the oldest water rights on the river in western Colorado — a 1902 right to 1,250 cubic feet of water per second.
That right has limited the ability of Front Range water users with more junior rights to divert Colorado River water. It helps keep water flowing down-river not just to the plant, but further downstream because the plant’s water use is nonconsumptive, benefiting municipal and agricultural water users, recreational river users and the environment.
However, the river district and regional water users have worried about the potential impacts on the river and water users whenever the aging plant is out of service and not calling for water under its senior right, such as when it requires maintenance.
To address that concern, reservoir operators including the river district, Denver Water and the U.S. Bureau of Reclamation agreed in 2016 to cooperate to maintain river flows at levels mimicking Shoshone’s normal operation, with certain exceptions.
Modified reservoir operations to mimic those flows are now in effect, and will remain so until snowmelt runoff causes the river flow to exceed the current outage protocol target of 1,250 cubic feet per second.
Pokrandt said that among the benefits of protecting flows, more water in the river means lower concentrations of total dissolved solids in the river due to dilution, reducing the need for water treatment by municipal water providers that rely on the river.
Kirsten Kurath, an attorney who represents the Grand Valley Water Users Association, a party to the 2016 agreement, said a big benefit of the Shoshone flows is maintaining flows in what’s known as the 15-mile reach of the Colorado River in Mesa County. Efforts to protect endangered fish in the river focus in part on maintaining adequate flows in that stretch of the river, upstream of the Gunnison River confluence…
While Grand Valley irrigators also have senior water rights on the river, Kurath said the Shoshone water smoothes out the river’s flows, making it easier for irrigators to plan and making water diversions more efficient than when flows are lower. “Everybody downstream always benefits as you keep water in the river,” she said.
The Orchard Mesa Irrigation District and Grand Valley Irrigation Co. are among other parties to the 2016 deal. As of late Monday afternoon, Xcel hasn’t yet said how long the power plant may be out of commission. According to the river district, Xcel has said that the COVID-19 outbreak is complicating repair plans…
The current outage agreement is in effect for 40 years. The river district says it and its West Slope partners are exploring ways to permanently protect the river flows.

Increase the reservoir release by approximately 25 cfs (carried out by High Country Hydro, Inc. personnel). After this change, the flow at the Fryingpan River gage below Ruedi Reservoir is expected to increase from 135 cfs to approximately 160 cfs, with a gage height of 1.76 feet.
Releases from the Aspinall Unit will be increased to 1050 cfs on Wednesday, March 25th. Releases are being adjusted to accommodate the change in diversions to the Gunnison Tunnel, which will occur on Thursday, March 26th. Snowpack in the Upper Gunnison Basin is currently at 106% of normal. The March 15th runoff forecast for Blue Mesa Reservoir predicts 78% of average for April-July inflows. Flows in the lower Gunnison River are currently above the baseflow target of 1050 cfs. River flows are expected to stay above the baseflow target for the foreseeable future.
Pursuant to the Aspinall Unit Operations Record of Decision (ROD), the baseflow target in the lower Gunnison River, as measured at the Whitewater gage, is 1050 cfs for January through March.
Currently, Gunnison Tunnel diversions are at 300 cfs and flows in the Gunnison River through the Black Canyon are around 400 cfs. After this release change Gunnison Tunnel diversions will be at 500 cfs and flows in the Gunnison River through the Black Canyon will be around 550 cfs. Current flow information is obtained from provisional data that may undergo revision subsequent to review.
The release from Ruedi Reservoir will increase the afternoon of March 26 by 50 cfs. The flow at the Fryingpan River gage below Ruedi Reservoir will change from 85 cfs to 135 cfs where it will remain for the near future.
For any concerns regarding Ruedi Reservoir operations please contact either Brittany or Elizabeth Jones at (406) 247-7611 or (406) 247-7618.
On Thursday, March 26 at 1600, increase the reservoir release by approximately 50 cfs (carried out by High Country Hydro, Inc. personnel). After this change, the flow at the Fryingpan River gage below Ruedi Reservoir is expected to increase from 85 cfs to approximately 135 cfs, with a gage height of 1.64 feet.
Municipal water providers in Aspen, Vail, Steamboat and other communities say there is no threat from COVID-19 in their water supplies and that people do not need to hoard bottled water — provided that the employees who operate the various water plants can still come to work.
And yet, two weeks into Colorado’s crisis, you still see people exiting the state’s grocery stores with shopping carts brimming with multipacks of 4-ply Charmin or Angel Soft toilet paper. And buried under the TP, you’ll spot the 48-bottle cartons of Arrowhead or Fiji water.
Toilet paper aside, water systems operators around the state — including ski towns, which are among the hardest-hit areas for the novel coronavirus pandemic — do not understand why people think they need to stock up on bottled water.
“Aspen Water provides safe, high-quality water that exceeds all stringent state and federal drinking-water regulations,” said City of Aspen spokeswoman Mitzi Rapkin. “Aspen’s water-treatment methods use filtration and disinfection process which remove and inactivate viruses.”
The same is true for Front Range water utilities.
“We have wastewater-treatment facilities that work above and beyond the standards devised for us, so there is no worry that water would be impacted by COVID-19,” said Ryan Maecker, spokesman for Colorado Springs Utilities, where surrounding El Paso County is second only to Denver in the number of confirmed COVID-19 cases in the state.
Those drinking-water standards, established by the Safe Drinking Water Act in 1974, are enforced by the U.S. Environmental Protection Agency and Colorado Department of Public Health and Environment.
“The water is treated and it’s disinfected, which takes care of all viruses,” said Linn Brooks, general manager of Eagle River Water and Sanitation District in eastern Eagle County, which has the third-highest number of confirmed COVID-19 cases in the state.
Officials say water should be the least of anyone’s concerns during the growing outbreak, which has prompted an unprecedented statewide stay-at-home order and has seen most nonessential businesses and schools shut down.
“No, there are no water shortages. No, municipal water is not a vector for COVID-19,” said Zach Margolis, utility manager for Silverthorne Water & Sewer in Summit County.
According to the U.S. Centers for Disease Control and Prevention, the coronavirus is thought to spread in the following manner: “Mainly from person-to-person between people who are in close contact with one another (within about 6 feet) … through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.”
Michelle Carr, distribution and collection manager for the City of Steamboat Springs Water and Sewer, attended a CDC webinar on the topic of COVID-19 and drinking-water systems.
“It said that the coronavirus is essentially very susceptible to our disinfection processes, and that while our disinfection process targets bacteria, bacteria is less susceptible than this virus,” Carr said. “So, the fact that we’re treating for killing bacteria means that we should adequately be taking care of the COVID virus.”
Buying bottled water during the ongoing pandemic makes no sense, she said.
“Our water is completely safe to drink,” Carr said. “I don’t anticipate that there will ever be an issue where we’re spreading COVID-19 through the treated potable water system. The bottled water is completely unnecessary.”
Brooks won’t speculate on why people are hoarding toilet paper, but she does have a theory regarding the stockpiling of bottled water.
“I think (people) see communications on how to isolate at home, how to prepare to a shelter in place, how to deal with emergencies, and those instructions almost always tell you to get bottled water,” said Brooks, adding that some people inexplicably prefer to drink bottled water all the time. “I don’t particularly understand that because our water here is so great, and (bottled water) certainly has an environmental impact.”
Various municipal, county and state emergency declarations have been enacted, covering water systems, but officials say those mostly just allow them to apply for state and federal funds or obtain additional equipment if necessary. Most water providers and wastewater-treatment operators are planning for staff shortages and doing everything they can to keep their staff healthy.
“We are not aware of any specific threats to our water system,” said Aspen’s Rapkin. “We have taken proactive measures to isolate our operations staff in order to continue to provide this critical community resource.”
Brooks agrees that staffing is the biggest concern as the virus spreads.
“Our biggest risk is absenteeism of our operators,” she said. “But, that being said, we can run with a pretty lean crew even if we got into some pretty significant absenteeism, as long as it doesn’t hit everyone at once, which we don’t think is likely at all.”
Eagle River Water and Sanitation District, which treats and provides water for users from East Vail to Wolcott along Interstate 70, took steps to mitigate against absenteeism early on.
“We knew that that was going to be our biggest risk and that protecting our employees was the most important thing that we could do. That’s our highest priority — to keep our staff healthy,” said Brooks, who added that any staffer with a symptom of any kind must stay home from work and not return until they have been free of symptoms for 72 hours.
Even if smaller mountain utilities were to be hit suddenly by a COVID-19 outbreak and get into staffing problems, other water-systems operators would step in to help. A cooperative venture among all utilities across the state and codified with intergovernmental agreements dictates that if a utility needs assistance, others will provide aid.
“So, if there’s somebody that has a plant failure, and we have staffing, we will send our staffing to them,” City of Aurora Water Department spokesman Greg Baker said during a call with other Aurora and Colorado Springs water officials. “I know Colorado Springs has been heavily involved in (mutual assistance) as well, so that should really not be a major concern.”
The desire to hoard bottled water, on the other hand, escapes officials.
“The bottled-water hoarding is a phenomenon we do not understand, because we bring safe, high-quality drinking water to your house,” Baker said. “We deliver it for a half a penny a gallon, so why are people going out and buying water? We do not understand that at all.”
Also, all the plastic is an environmental issue, Baker said, and transporting it around the state or out of state in bottles removes local water from Aurora’s extensive reuse system for irrigation and agriculture.
“So, whenever people take bottled water and start shipping it out, you’re kind of losing that reusable component, and that impacts our culture because we’re so used to reusability. So that hurts us there,” Baker said. “It also hurts us through the fact that, frankly, we have some of the highest-quality water in the state, and why do you need it in a bottle? It’s as irrational as the toilet-paper hoarding.”

A bill that cleared the Colorado legislature with bipartisan support March 4 seeks to resolve an eight-year debate over how ranchers and other water users can maintain their historical water use when dry conditions trigger cutbacks to protect streamflows.
HB20-1159 [State Engineer Confirm Existing Use Instream Flow], which passed the House with a unanimous 63-0 vote and the Senate with a 31-1 vote, authorizes state water officials to confirm historical usages, such as water used for livestock, whether or not it’s held in an official water right. This allows ranchers’ uses to stay first in line for water ahead of the stream protections, known as instream-flow rights.
“It’s really a belt-and-suspenders clarification of existing authority,” said Zane Kessler, director of government relations for the Colorado River Water Conservation District, which drafted the language for the bill. “I think it’s a good example of when we sit down and pore over these issues, it’s not hard to come up with a fix that protects West Slope water users and provides the state engineer the authority he needs to continue administering them.”
Instream-flow rights, which are held exclusively by the Colorado Water Conservation Board, exist for the sole purpose of preserving the natural environment of streams and lakes “to a reasonable degree.” Most of these date to the 1970s and are junior to most agricultural-water rights under Colorado’s prior appropriation system of “first in time, first in right.” To date, instream-flow rights protect roughly 9,700 miles of stream in Colorado.
The debate over historical uses has turned on whether a water user must go to water court to make their pre-existing use official in a decree.
A 2012 drought brought the question to a head when state officials cut off water users on the Elk River in northwestern Colorado in favor of instream-flow rights. Although many ranchers in the area have water rights for irrigation that are senior to the 1977 instream-flow rights and have historically used that water also for their cattle, the state Division of Water Resources determined that livestock watering wasn’t implicit in irrigation rights.
Those without specific rights for stockwatering were left high and dry once the summer irrigation season was deemed over, even though they had used the water for livestock for generations.
“My grandparents bought this piece of land in 1946,” said Krista Monger, a cattle rancher on the Elk River. “We have the records to show we’ve been using (our water) for livestock.”
Stockwatering and irrigation often go hand in hand. During the irrigation season, if a rancher’s livestock drink from the ditches used to irrigate their fields, the use is considered incidental to irrigation. But once the growing season is over and a rancher keeps the water flowing through the ditch for the exclusive purpose of watering their livestock, the use is not covered under irrigation-water rights.
The amount of water typically used for exclusive stockwatering is a fraction of what is used for irrigating, around 80% to 90% less. Some ranchers also use stock ponds, which require a water-storage right.
More than 90,000 irrigation-water rights are held across the state, of which 29,000 specifically name both irrigation and livestock uses. That means the new law could potentially apply to 61,000 water rights, although not all of these are held by ranchers raising livestock. An additional nearly 32,000 water rights are held exclusively for livestock purposes but not irrigation.
The Monger family holds both irrigation- and livestock-water rights to grow hay and to water their 300 cattle. Her family’s rights and diligent record-keeping meant their ditches kept flowing while their neighbors’ ditches were shut down in 2012, highlighting the need for better record-keeping among the region’s irrigators.
But the incident prompted a statewide debate over the meaning of Colorado statute C.R.S. 37-92-102(3)(b), which states that instream-flow rights are subject to pre-existing uses of water, “whether or not previously confirmed by court order or decree.”
The state Department of Natural Resources, home to both the Division of Water Resources and CWCB, argued that when the instream-flow protections were created, lawmakers intended for water users to make their existing use official in a decree. The Colorado Cattlemen’s Association and the Colorado River Water Conservation District argued that the statute clearly precludes the need for a court decree and sought to protect ranchers’ historical usage without requiring them to go to water court.
“The statute says… prior uses would be honored. But they’re saying the statute doesn’t say what the statute says,” said Mike Hogue, former president of the cattlemen’s group.
After years of negotiations, stakeholders agreed on a simple piece of legislation to clarify the state water engineer’s authority “to confirm a claim of an existing use (if it) has not been previously confirmed by court order or decree,” according to the bill summary. The bill had bipartisan sponsorship from Reps. Marc Catlin, R-Montrose, and Dylan Roberts, D-Avon, and Sens. Don Coram, R-Montrose, and Kerry Donovan, D-Vail.
“I do think this is very helpful legislation,” said State Engineer Kevin Rein, who is with the Division of Water Resources. “We had what I’d call an honest disagreement about what the statute meant. My position is if they change the law and give me a place to hang my hat on, that solves the problem.”
However, what the legislation doesn’t resolve — and what is perhaps a bigger Pandora’s box opened by the 2012 incident — is the decision that state water officials made that irrigation rights do not include stockwatering rights. In practice, irrigators around the state, many of whom hold water rights dating to the late 1800s and early 1900s, have used irrigation- or agricultural-water rights not to just irrigate their hayfields, but also to water their livestock.
The new distinction means that ranchers with irrigation rights must apply for livestock water rights if they want to protect their usage into the future. Although the new legislation protects a rancher’s stockwatering use from being shut off specifically by an instream-flow right , their stockwater use could still be cut off if another water user makes a call on the river to fulfill a formal water right.
“We all thought that was part of our ag water rights,” said Doug Monger, a Routt County commissioner and a cattle rancher on the Yampa River in northwest Colorado, and also uncle to Krista Monger. “It’s a wakeup call for all of us.”
