Water saved through upper-basin program unlikely to move needle for Lake Powell
Western Slope projects are small and involve agriculture
Three of western Colorado’s biggest irrigation districts are not participating on a large scale in a federally-funded program to conserve water, and the amount of water saved by the program overall won’t be enough to rescue depleted reservoirs.
The rebooted System Conservation Program was one of the legs of the Upper Colorado River Commission’s (UCRC) 5-Point Plan, announced in July and aimed at protecting critical elevations in Lake Powell and Lake Mead, which have fallen to record-low levels in recent years because of overuse, drought, and climate change. System conservation will take place in the four upper Colorado River basin states — Colorado, New Mexico, Wyoming, and Utah — and will pay water users to cut back. It’s being funded by $125 million from the federal Inflation Reduction Act.
The total water estimated to be saved across the upper basin for this year of the restarted, temporary, and voluntary System Conservation Program is nearly 39,000 acre-feet. By comparison, Lake Powell when full holds more than 23 million acre-feet; Ruedi Reservoir, on the Fryingpan River, can hold about 100,000 acre-feet. (An acre-foot is the amount of water needed to cover an acre of land to a depth of 1 foot and can supply one to two households a year.)
Becky Mitchell, Colorado commissioner to the UCRC, said in a UCRC meeting last month that although the upper basin will do its part in response to last summer’s calls from the federal government that the seven Colorado River basin states needed to conserve 2 million to 4 million acre-feet of water, the majority of that needs to come from cuts in the lower basin (California, Arizona, and Nevada).
“(System conservation) will not resolve the crisis in the reservoirs,” she said.
Last month the UCRC approved moving forward with executing agreements with program participants, which are still being finalized.
Although a goal of the program was to get participation across all water sectors — agricultural, municipal, and industrial — all of the projects proposed in Colorado involve Western Slope agriculture. None of the state’s Front Range water providers — which collectively take about 500,000 acre-feet per year of the Colorado River’s headwaters across the Continental Divide to thirsty cities and farms — are participating.
Paying water users to irrigate less has long been controversial on the Western Slope, with fears that these temporary and voluntary programs could lead to a permanent “buy and dry” situation that would negatively impact rural farming and ranching communities.
Of the four upper basin states, Colorado has the largest number of projects (29) but the least amount of saved water (3,532 acre-feet). This is an indication that most of Colorado’s participants are proposing small projects. UCRC Executive Director Chuck Cullom said if the program is undertaken again, officials may consider a minimum size requirement because doing very small projects may not be worth it.
“From a practical standpoint of the cost of monitoring and administering a verification program for that (small number of) acres may not pencil out relative to the amount of water conserved,” he said.
Of the 29 Colorado projects, most involve reducing water use for forage crops, according to information provided by UCRC. Eight involve fallowing grass hay as part of a cow-calf operation, saving 1,163 acre-feet of water; seven plan to fallow alfalfa and save 1,029 acre-feet; and eight propose switching to less-thirsty crops, saving 791 acre-feet.
The UCRC received 88 proposals across the four states, 72 of which met the qualifying criteria. Utah has 20 projects that meet preliminary criteria; Wyoming has 22, and New Mexico has one. The UCRC’s opening offer was $150 per acre-foot of saved water, but the average compensation will probably end up being higher — $434 per acre-foot, according to information provided by UCRC.
Grand Valley Water Users Association not participating
Although some water users in the Grand Valley Water Users Association (GVWUA) participated in the original system conservation pilot program, which ran from 2015 to 2018 and conserved 47,000 acre-feet of water at a cost of about $8.6 million, they won’t be taking part this time around.
GVWUA, whose Highline Canal delivers water to roughly 24,000 acres of farmland on the north side of the valley between Grand Junction and Mack, withdrew its application from the process after manager Tina Bergonzini said she couldn’t come to an agreement on the price with the UCRC. GVWUA had rejected the concept of paying farmers based on an amount of unused water, instead proposing to pay farmers for each acre of land they took out of production.
Individual farmers would have had to apply to the program through the association, which proposed to cap total member participation at 1,000 acres and 3,000 acre-feet of water.
GVWUA was asking for between $686 and $1,306 per each acre fallowed, depending on whether farmers reduced water use during the entire irrigation season or just part of it.
Bergonzini said the price represents what it would cost to administer the program in a way that provides equity and protection; at any lower price, the funding from system conservation would not be enough to cover the extra staff and engineering costs. Cullom said his organization was unlikely to approve those costs, so GVWUA withdrew its application.
“They were not wanting to pay per acre what we had requested,” Bergonzini said. “They had a line drawn in the sand and so did I.”
The Grand Valley Irrigation Company (GVIC), which serves about 40,000 acres of farmland between Palisade and Mack, has four projects proposed within its service area, covering a total of 120 acres and 285 acre-feet of water savings.
“It’s not a very big amount,” said GVIC Assistant Superintendent Charlie Guenther. “I did hear from a handful of ag people that they didn’t want to be part of this because it sounded very technical, and it was government involvement. That’s something that came up.”
Unlike GVWUA, individual water users within GVIC did not have to apply to the program through the irrigation company, and the company’s board did not take a stance on whether or not to support system conservation, according to him.
There is just one conservation project proposed in the boundaries of the Uncompahgre Valley Water Users Association (UVWUA), the largest irrigation district in Western Colorado, at more than 83,000 acres of farmland in Delta and Montrose counties. The project would enroll about 33 acres in the program and would result in about 46 acre-feet of water savings.
UVWUA manager Steve Pope said the system conservation program didn’t get much interest from his water users because of the timing. Bergonzini agreed.
“They didn’t want to do a last-minute thing,” he said. “By the time this thing was rolled out, these guys had already made their decisions, and they were already committed for the next season.”
Cullom has acknowledged that there were shortcomings with the program’s rollout. The UCRC unveiled details of the program in December, with an original application deadline of Feb. 1, which was later pushed to March 1 for this summer’s irrigation season.
“We need to do much better when we think about how to do this in the future, if we do this in the future,” he said. “We need more clarity on the data requirements, what we expect from a proposal. We need to give people more time to engage in understanding what the opportunity is and we need to start sooner. Start in the fall for an irrigation season instead of January.”
Conservation district concerns
The Western Slope’s two largest conservation districts — the Colorado River Water Conservation District (CWCD) and Southwestern Water Conservation District (SWCD) — submitted letters to the UCRC, stating their concerns with the program. Mitchell had promised the districts that they could participate in the review and approval process for applications, thereby securing a measure of local control. But in March, she walked back that commitment, saying the UCRC had sole authority in the approval process.
The UCRC has released few details so far on project proposal specifics, and publicly available applications have been heavily redacted. In addition to redacting the applicants’ personal identifying information, nearly everything else has been blacked out: the precise location of projects; which streams and ditches are involved; details of the water rights involved; and how much the applicants are asking to be paid for their water.
The districts say this makes it impossible to meaningfully review them to determine whether the projects would cause injury to other water users. Their letters to the UCRC say the lack of transparency raises questions about whether public funds are being used wisely.
“In short, SWCD is very disappointed and concerned about the process that has been undertaken by the UCRC and the state of Colorado,” reads the letter from Southwestern General manager Steve Wolff.
In response, Amy Ostdiek, CWCB section chief for interstate, federal, and water information, said that the review process respected project proponents’ privacy and that striking a balance between transparency and privacy is an ongoing effort.
“The Colorado State Engineer’s Office has been directly involved as implementation agreements and verification plans are developed to ensure no injury results from SCPP participation,” she said in an email.
She said additional information will be available when the UCRC finalizes agreements with project participants, which should happen late this month, according to Cullom.
The 39,000 acre-feet of water across the four upper-basin states will do little to boost Lake Powell. It’s the proverbial drop in the bucket. But the political value of 39,000 acre-feet may be far greater than any benefit to the nation’s second-largest reservoir. The effort shows that upper-basin water managers are willing to do their part to prevent the system from crashing, but that part is small compared with the cuts they say are needed in the lower basin.
“It’s unlikely any system conservation stood up in the upper basin is going to move the needle,” Cullom said. “But it’s important for the upper basin to participate and contribute within the resources and the tools we have available, and what we are demonstrating in this process is that we do have tools, we do have resources. They are narrow in scope and small in volume.”
