The Uncompahgre Valley Water Users Association (UVWUA) will be diverting an additional 100 cfs through the Gunnison Tunnel Monday morning, April 14th. At the same time, releases from Crystal Dam will also be increased by 100 cfs, from 850 cfs to 950 cfs. After this change, the total flow through the Gunnison Tunnel should be about 500 cfs, which should leave about 450 to 500 cfs in the Gunnison River downstream of the tunnel.
From the Glenwood Springs Post Independent (George Sibley):
Concern about possible transmountain diversions dominated a public information-and-input meeting in Gunnison on Gunnison Basin Roundtable water planning.
The Gunnison County Commissioners hosted the meeting during their work session Tuesday, March 25. Thirty-five or 40 citizens participated in the discussion through the course of a two-hour meeting.
The water plan under consideration was the Gunnison Basin Roundtable’s contribution to the Colorado Water Plan ordered by Governor John Hickenlooper in May 2013; the plan will create possible solutions for a significant gap between the known water supply and the needs of a population projected to grow 60-100 percent by mid-century, mostly in the Front Range metropolis. Presenting information on the Gunnison Basin plan were roundtable members Frank Kugel, Rufus Wilderson and George Sibley.
The meeting focused mainly on goals that have been identified for the Gunnison Basin over the next four decades, and some “statewide principles” that it hopes to persuade at least the other West Slope basin roundtables to adopt in negotiations for the statewide water plan; some may be acceptable to all eight state river basins plus the metro area.
The priority goal stated for the Gunnison Basin is “to protect all existing water uses.” Roundtable members, according to Sibley, feel that the Gunnison Basin now has a good mix of consumptive uses (agricultural and municipal/domestic/industrial) and non-consumptive uses (environmental, recreational and hydropower), town-and-country, working-and-playing landscapes, and they want to carry that forward into the future. Change should be incremental, and weighed against its impact on existing uses.
Some of the citizen input warned the roundtable presenters to anticipate possible major changes in the headwaters region, from the oil and gas industry and potential mining operations for copper, molybdenum and “rare earth” minerals. Several citizens wanted to see more focus on water quality.
Other intra-basin goals discussed supporting the priority goal. While the planning process was brought about by a projected metropolitan water shortage, the municipal/industrial shortage in the Gunnison Basin is projected to be small, around 6,500 acre-feet (enough for approximately 13,000 four-person households) — roughly one percent of the projected statewide municipal/industrial shortage, and probably manageable through some anticipated agricultural land-use changes.
The heavily agricultural basin does, however, have a significant existing shortage of agricultural water, mostly late in the season, limiting the productivity of the land. Concern over these shortages is not limited to the ranchers; it acknowledges the close relationship between the valley’s agricultural land base and its economically important non-consumptive uses — the environmental and recreational uses also dependent on the extensive groundwater storage, wildlife wetlands and increased late season flows that result from irrigated floodplains, as well as aesthetic open-space considerations.
Most of the concerns expressed by the citizens present, however, reflected a Gunnison Basin antipathy toward headwaters diversions across the Continental Divide going back to the 1930s. These fears were not entirely allayed by the “Statewide Principles” being advanced in the Gunnison Plan. Kugel and Sibley explained that the strategy was to set the bar so high, for Front Range demand reduction preceding any diversion and West Slope compensations in exchange for any diversion, that the diversion would prove to be economically unfeasible. This strategy is furthered by the fact that both the Gunnison and Upper Colorado Basins are now over-appropriated in sub-average water years; any new diversion would be limited to above-average water years — a serious risk for the Front Range water suppliers to contemplate, given the projections for climate change on the one hand and the high cost of “pumpback” projects on the other.
That notwithstanding, the message from the audience was clearly for the roundtable to not be “soft” on the inevitable discussion of further transmountain diversion from any West Slope basin, since water removed from any of them increases the amount of water the other basins must send downstream for still undefined Lower Basin obligations.
Other public-input meetings are planned for other communities throughout the Gunnison Basin over the coming weeks. In addition, a public survey is available online, through the Upper Gunnison River District website — http://www.ugrwcd.org.
The roundtable is now moving into the stage of generating specific plans for meeting the identified needs and expressed goals. The roundtable meets the first Monday of every month, except for January, July and September, at 4 p.m. in the Holiday Inn Express in Montrose; the meetings are open to the public. The meeting on June 2 will precede a “State of the River” informational event held in conjunction with the Colorado River District at 7 p.m.
Snow forecast for the central mountains of Colorado this weekend will further bury the melt-hastening layer of dust that blasted the state 11 days ago.
“Wherever dust is exposed, the fresh snow will hopefully bury it and postpone the dust effect a little longer,” said Silverton’s Snow and Avalanche Studies director Chris Landry, who has chronicled the impact of desert dust blanketing Colorado snowpack since 2003.
But the fresh snow will only delay the detrimental impact of those dust layers.
“Without a doubt this dust layer has done its deed, helping to melt the snow. The danger is getting more dust. Eventually dust layers converge, melting out the clean snow between them and then really help burn through the snowpack,” said Jim Pokrandt with the Colorado River Water Conservation District. “Right now, we aren’t especially alarmed. But those spring winds are swirling.”
The speedy melt sends a deluge downstream that not only elevates flood potential, but hinders the ability of ranchers and farmers to retain or use the water before it rushes out of state. (And, on a more minor note, it’s marred plenty of formerly pristine ski slopes.)
Without the dust, a gradual, natural melt cycle keeps things more manageable. While this season has yet to match last season — which had two huge dust events in April — the regularity and impact of dust so far this season is pacing with the last decade, Landry said.
The first-week of April is the halfway mark of the typical dust season.
Landry and his crew have so far measured five dust events at 11 Snotel sites on mountain passes across Colorado.
March 30 and April 1 events in Crested Butte, Aspen and across the southern San Juans were dramatic — with ominous red skies preceding a choking swirl of dust — but they likely will not match the huge event of April 8 last year. On that day, a whopper of a storm coated western Colorado with a layer of dust that measured 47.5 grams per square meter, more than the total annual accumulation of dust in any year since Landry began measuring in 2003.
A two-day dust event that began April 15 last year blanketed the central and Front Range snowpack with a layer measuring 9 grams per square meter, another record event.
With snow continuing to accumulate, the melt has not begun in most high-altitude parts of Colorado, meaning those dust layers have yet to see direct sunlight, Landry said.
“The snowpack at those elevations are still retaining some cold,” he said.
From the Fort Collins Coloradoan (Ryan Maye Handy):
Northern Water, which manages water stored throughout a massive system of linked reservoirs in Northern Colorado, set its annual water quota at 60 percent, despite customer requests to receive 70 percent of their full potential water allotment.
Since 1957, Northern Water has issued the water quotas, which dictate the amount of water from the Colorado-Big Thompson and Windy Gap projects that will flow to cities, industrial complexes and farmers in Northern Colorado. The city of Fort Collins typically gets half of its water from the Colorado-Big Thompson Project, and has been particularly dependent on the system after High Park Fire debris polluted the Poudre River.
Fort Collins was among customers who lobbied Northern Water for a 70 percent quota on Wednesday, during a stakeholders meeting held to discuss this year’s quota. Despite those requests, Water Resources Manager Andy Pineda recommended that Northern Water’s board opt for a 60 percent quota.
A few factors went into Pineda’s recommendation, including Colorado’s above-average snowpack, high reservoir levels, and the general absence of drought in Northern Colorado. Spring runoff this year is expected to release an extra 100,000 acre feet of water down area streams and rivers, which should limit the region’s need for supplemental water from the Colorado-Big Thompson.
Pineda’s opinion was not shared by all. A few farmers asked the board for a 70-100 percent quota to help them plan for the growing season. Fort Collins wanted 70 percent to help offset troubles with Poudre River water quality. There is also a chance that Lake Granby reservoir will spill over this June, and a few stakeholders were concerned that water would be wasted with a reduced quota.
From email from the Colorado Water Conservation Board (Ben Wade):
A Joint Flood & Water Availability Task Force meeting will be held on Wednesday, April 16, 2014 from 1:00-4:00p at the Colorado Parks & Wildlife Headquarters, 6060 Broadway, Denver in the Bighorn Room.
With continuing population growth in Southwestern states and ongoing drought, water issues are becoming more and more about who has to cut back their use when there isn’t enough to meet demand.
That thread ran through presentations at the annual Water Seminar on April 4 in Durango, sponsored by the Southwest Water Conservation District.
“How will we handle the water and other needs of 10 million people,” asked John Stulp, a former state agriculture commissioner and current chair of the Interbasin Compact Committee (IBCC) which is developing a State Water Plan along with nine basin water roundtables…
Harris cited a statewide statistic that with municipal water use, half is used inside and half outside. Ninety percent of the inside use returns to the stream. With outside use, 70 to 80 percent is “consumed” and does not return to the stream. The Southwest Roundtable has approved a goal to shift the percentage of municipal use to indoor, especially where the water comes from ag dry-up or trans-mountain diversion, he said.
Harris initiated the idea of legislation to limit lawn sizes in residential developments after 2016 where the water would come from a permanent transfer from ag. It didn’t get through the State Senate but will be a study topic by an interim committee on water resources during the off-session.
“The lawn bill, this is just the first time, not the last,” Harris asserted. “Reduction of lawn size is a significant conservation measure to help meet 2050 water supply.”
State Rep. Don Coram from Montrose commented “On the Front Range, they haven’t addressed storage or depleting the aquifer. They are more interested in trans-mountain diversion.”[…]
John McGlow from the Upper Colorado River Commission said curtailment such as this will affect water rights decreed after the 1922 Colorado River Compact. The Upper Basin is western Colorado, eastern Utah, southwest Wyoming, and northwest New Mexico. They have begun discussions on how cutbacks would be shared, or how to avoid getting to that point with things like fallowing fields and reducing frequency of irrigation.
“Lake Powell is our bank account for complying with the compact,” he said. It’s the cushion for the Upper Basin states to deliver mandated quantities of water to the Lower Basin states (California, Arizona and Nevada) and Mexico over a 10-year average. Navajo Reservoir also is part of that.
McGlow said 1999 was the last year that Powell was full. The goal is to get enough water into Lake Powell each year to avoid curtailment or the possibility of the water level getting too low for hydropower generation, which he said would have its own serious impacts.
The good news is there’s enough snowpack in northwest and north central Colorado that these won’t be issues this year, McGlow said…
Panelist Dan Birch from the Colorado River Conservation District said most pre-compact rights on the Western Slope are in the Grand Valley and Uncompaghre Valley. There is around 1 million AF of pre-compact irrigation on the West Slope, he said. Most of that land is in pasture or hay. Pasture can’t be fallowed, he said.
With a target to make up for 350,000 AF of post-compact use, Birch said, “I don’t think we want one-third of ag to go away. What we’re talking about is interruptible voluntary market-based contracts” for pre-compact users to reduce their water use. “This has to work for the farmers and the ditch companies,” he said.
Birch said power plants in Northwest Colorado are significant post-compact water users. “In the event of a (water) shortage, it will be important to keep critical uses going,” including power generation, he said.
Demand management is a key to avoiding Upper Basin curtailment or loss of hydro generation. “We are way behind on actual implementation of demand management,” including agricultural fallowing and reducing municipal demands, McGlow said. “It’s still a concept. It’s in its infancy.”
Fallowing and reduced irrigation are part of what’s called water banking. Panelist Aaron Derwingson said, “Pretty much everyone supports water banking in concept. It gets a lot more complex actually doing it.”
“If you like your toilet, you can keep your toilet.” Does that sound familiar? Does it sound like the Affordable Care Act?
One of the longest- and hardest-fought floor debates last week had to do with toilets. The sponsor actually made that statement. The bill will require that all new shower and toilet fixtures be energy-efficient to conserve water. Our own Colorado Water District supports it in the hope that the Front Range will divert less water. But I don’t think government should limit choice unless it’s a public safety issue or offers some other very clear benefit. I have to flush the efficient toilet in our rented Denver apartment about three times, so I don’t think they work as advertised. The shower, in this touted “green energy-efficient” building, takes five minutes of running in order to get hot water.
But water conservation is a very serious topic in Colorado. Follow the progress of the water plan being developed this year. It supposedly will guide water use and conservation for years into the future…
We had a very controversial bill and debate in the Agriculture Committee that could have a big effect on water for irrigation and stream flow in our area. The bill would allow irrigators to use more efficient means of watering crops and fields and then sell or donate the saved water to keep our streams flowing all year. I like the concept, but we can’t seem to get agreement between the irrigators, lawyers, fishermen like me and environmentalists.
We haven’t voted as of this writing. I would like to see us work on the bill this summer and come back with agreement, since I really don’t think the committee, of which I am a member, is capable of sorting out this complicated water law issue.
The Blue and the Snake are in trouble. These two Summit County rivers are part of the Upper Colorado River Basin, which was named the second most endangered river in the country Wednesday by American Rivers, a Washington D.C.-based nonprofit focused on river advocacy.
“If you want to have healthy rivers and a recreational economy and agriculture on the West Slope, there really is nothing left to take,” said Ken Neubecker, associate director of the organization’s Colorado River project…
The nonprofit’s biggest fear is a new diversion, Neubecker said, because taking a lot of water out of the Colorado anywhere would have serious repercussions.
American Rivers and other conservation organizations say the Colorado Water Conservation Board, charged with creating the state water plan, should make sure it prioritizes river restoration and protection, increases water efficiency and conservation in cities and towns, improves agricultural practices and avoids new transmountain diversions.
Rivers on the Western Slope are already drained and damaged, Neubecker said. He called it wrong to divert more water instead of focusing on alternative methods to meet the gap between water supply and demand.
Right now, he said, details on a new diversion project have been vague, but Front Range proposals have considered developing the Yampa, Flaming Gorge and Gunnison and taking more water out of the Blue, Eagle, Roaring Fork and Fryingpan rivers…
The Colorado River and its headwaters are home to some endangered fish species. They support wildlife, agriculture and multi-billion dollar tourism industries.
And they provide some or all of the drinking water for the resort areas of Breckenridge, Vail, Aspen, Steamboat Springs, Winter Park and Crested Butte and most of the urban Front Range.
To meet its customers’ water needs, Denver Water is focused on Gross Reservoir enlargements as well as conservation and forest health efforts, said CEO Jim Lochhead Thursday.
Colorado’s largest water provider has no current plans to construct a new transmountain diversion, he said, but the state as a whole should consider that option.
A new diversion is “probably inevitable at some point,” he said. “We want to do that in partnership with the West Slope.”
And after signing the Colorado River Cooperative Agreement last year, the utility has to.
The agreement does not allow future water development without the permission of all parties, including Western Slope representatives. Lochhead said, it “establishes a framework where we are really working together as partners instead of the old framework of East Slope versus West Slope.”
But the push is not coming from Denver Water.
“They’re really not the ones that are after a new diversion,” Neubecker said. “They got what they want.”
Pressure for more water from new or existing transmountain diversions comes mainly from north and south of Denver, the Arkansas and South Platte basins and especially Douglas County, he said. Those areas should look at conservation efforts more seriously, he said, and “pay attention to land use policies that basically encourage wasteful water use.”[…]
“We’ve got to start thinking about rivers as rivers” instead of engineering conduits for delivering water, Neubecker said, and “understand that we may think that growth should be infinite, but the resources like water that support the growth are not.”
From the Glenwood Springs Post-Independent (Mike McKibbin):
There is no more unclaimed water in the Colorado River Basin, so if the state’s population nearly doubles by 2050, as some have projected, the consequences for everyone along the river – including Rifle – could be dire. That was the message Louis Meyer, a civil engineer, president and CEO of SGM in Glenwood Springs, told City Council as he detailed the ongoing Colorado Water Plan process at an April 2 workshop…
Of the counties in the Colorado River basin, he noted, Garfield is projected to have the most growth, around 274 percent, or 119,900 people, by 2030.
“The Front Range is expected to have serious water shortages by 2020, unless they find more water,” he said. “They can’t take any more from agriculture on the Front Range, so they want a new supply from the Colorado River basin.”
“We have a target on our back,” Meyer continued. “But we have no more water to give.”
If every entity on the Front Range implemented some strict conservation measures, such as banning all new lawns and perhaps the removal of some existing lawns, Meyer said, the water gap could possibly be eliminated in coming years.
“But if we put that in the [water] plan, we need to do the same thing in our basin,” he added.
All storage water in Ruedi and Green Mountain reservoirs is allocated, along with nearly every other reservoir in the state, Meyer said.
Water quality issues are already becoming acute, Meyer said, because there is less water in the Colorado River.
From the Environmental Defense Fund (David Festa):
Restoring rivers: Four steps to a pulse flow
Can the pulse flow be replicated to restore rivers in other water stressed regions around the world? With apologies to the importance of the nuances of international water-sharing agreements, here’s my shorthand of the steps needed to get a pulse flow.
First, find water. Anywhere irrigation is critical to food production, agriculture is responsible for 70% or more of withdrawals from rivers, streams and groundwater. As societies realize the value of conserving water, money can be made available to incentivize farmers and managers of irrigation infrastructure to improve, voluntarily, irrigation efficiency. In other words, with the right incentives, they can maintain or improve their food production using less water.
Second, find a way to buy some of the saved water. Farmers who save water through efficiency can choose what to do with the “saved” water. One choice is to sell or lease it to someone else, using the payments to help defray the cost of improving efficiency.
Third, particularly for rivers where flow is generated by melting mountain snowpack, find a way to mimic a spring flood. Water savings accrue over time so releasing water as efficiency measures are put into place would produce but a trickle at a time. The key is to store enough water to make a difference. In this instance, Minute 319 broke new ground in international water sharing by allowing Mexico to store up water in Lake Mead, a short drive from the famous Bellagio fountains in Las Vegas.
Finally, prepare the way. Starting several years ago, farmers and conservation advocates worked together in the Colorado River Delta to plant and irrigate several hundred acres of restored native habitat. The natural condition for the delta includes periods of drought and periods of floods (natural pulse flows). Therefore, the ecosystem has evolved to take advantage of this kind of wet/dry cycle. The problem is that with only a handful of exceptions, the delta has not been wet through and through since before the early 1960s! Much of the natural vegetation had long since died out.
The hope is that the pulse flow will act like a cardiac defibrillator and shock the system back into its routine, albeit for only a portion of the historic delta. But the restored connection between the Colorado River upstream and the Upper Gulf of California should be a boon to the hundreds of bird species that migrate the Pacific flyway. Of course for this to be truly successful, it will require more pulse flows (scientists think, about one every five years) and a small amount of steady water (called base flow) in between just to keep things damp.
A new foundation for stewardship
Thanks to the painstaking approach taken by the architects of Minute 319, there is a solid foundation for this new approach to stewardship of the Colorado River.
Twin Lakes Reservoir & Canal Co. took umbrage at the way working drafts of an upcoming state water plan viewed its future. A report prepared by the Interbasin Compact Committee uses an example of a way to create new supply, suggesting that Twin Lakes could cut back its diversions from the other side of the Continental Divide in drought years to aid the Western Slope. Trouble is, Twin Lakes has no plans to do that, said Kevin Lusk, who is president of the Twins Lakes company as a representative of Colorado Springs Utilities, the majority shareholder in Twin Lakes.
“In our discussions, we’re trying to keep what we’ve got, and we have no intentions of increasing the use,” Lusk told the Arkansas Basin Roundtable Wednesday.
Lusk asked for a retraction of the statement by the Arkansas Basin Roundtable and from the basin roundtable chairs. The document was discussed in a March 17 conference call among roundtable chairs and alluded to in an Aspen Daily News story. Several roundtable members questioned how the statement landed in the document, since it was not discussed at a meeting.
“It was cited as an example in the process as we move forward,” said Betty Konarski, chairwoman of the roundtable.
Lusk said the distribution of the information is detrimental to Twin Lakes. While there have been past discussions along the same lines, the company has never committed to changing its operations to accommodate the Western Slope.
“Twin Lakes is not considering a reduction of diversions. We haven’t agreed to do it or not to do it,” added Alan Ward, water resources manager for the Pueblo Board of Water Works, the second largest Twin Lakes shareholder. “We wouldn’t have a reason to give any of it up unless there was some benefit to us. It’s gravity-flow and inexpensive water for us.”
But a minority Twin Lakes shareholder, the Lower Arkansas Valley Water Conservancy District, said the company should be more open to actions that could have a statewide benefit. comments,” said Jay Winner, general manager of the Lower Ark district. “I think the Twin Lakes company needs to be more open-minded. It’s looking at what’s good for Colorado Springs Utilities, not the whole state.”
NASA’s Aeronomy of Ice in the Mesosphere, or AIM, mission captured this image of noctilucent clouds over the poles in 2010. By compiling data from several missions at once, researchers have now created a record of the clouds at lower latitudes as well. Image Credit: NASA/AIM
FRISCO — If you’ve been seeing more strange clouds that glow at night, it’s not your imagination. The occurrence of those types of clouds increased between 2002 and 2011, according to a new study analyzing satellite data from a variety of sources. Combining the information and using computer models, the NASA scientists found the greatest increase in areas between 40 and 50 degrees north latitude, a region which covers the northern third of the United Sates and the lowest parts of Canada. The research was published online in the Journal of Geophysical Research: Atmospheres on March 18, 2014.
