‘Innovative thought and hard work’
have helped with sustainability

STATE Engineer Kevin Rein said his current description of the Upper Rio Grande Basin is “actually quite good” and acknowledged in a recent interview with the Alamosa Citizen the efforts of San Luis Valley farmers to restore sustainability to the river system.
Rein also recognized in an email QA the ongoing challenges in Subdistrict 1 of the Rio Grande Water Conservation District and with the unconfined aquifer. The Valley has two aquifers, the confined and unconfined, and Rein had characterizations of both based on the state’s rules and regulations governing the Upper Rio Grande.
The State Engineer will curtail water wells as part of the Colorado Division of Water of Resources’ daily administration of surface water and groundwater in the Valley. His views then of the Upper Rio Grande Basin carry significant weight with water users up and down the Rio Grande.
“My description of the current state of the Upper Rio Grande Basin (that portion of the basin within Colorado) is actually quite good. The water users have responded to the implementation of the Groundwater Rules, which brings about balance to the use of the water sources in the Basin.” said Rein.
He said he expects the $30 million earmarked for the Valley through the Groundwater Compact Compliance Fund sponsored by State Sen. Cleave Simpson of Alamosa will help Subdistrict 1, in particular, with efforts to retire more irrigated acres.
San Luis Valley farmers will talk until the cows come home about the critical work they’ve done to help restore the confined and unconfined aquifers of the Upper Rio Grande Basin. Rein, director of the Colorado Division of Water Resources, acknowledges as much.
“It has taken a lot of innovative thought and hard work from a lot of people in the Basin to achieve that,” he said. “These administration tools allow us to manage our water in good water years and bad water years. Add to that, we are in compliance with our interstate compact on the Rio Grande with Texas and New Mexico.”
To be clear, the Upper Rio Grande is far from being called a healthy river – particularly the unconfined aquifer, which runs west from the Alamosa and Saguache county lines in Subdistrict 1 of the Rio Grande Water Conservation District, and provides water to the lush potato and alfalfa fields that largely drive the Valley’s agricultural economy.
In a Q&A exchange with Alamosa Citizen, Rein gave further context to how efforts from the Valley’s farming and ranching community are paying dividends, but with a lot more work and sacrifice to come.
“I can’t downplay the frequency of the ‘bad water years’ and the fact that persistent drought has impacted both surface water users and groundwater users; that impact is felt across the Basin.”

Too many groundwater wells permitted by the state and two-plus decades of drought have taken a toll.
“I can’t downplay the frequency of the ‘bad water years’ and the fact that persistent drought has impacted both surface water users and groundwater users; that impact is felt across the Basin,” Rein said.
“It’s in the context of this climatic trend of reduced water supplies that the struggle to achieve sustainability in the unconfined aquifer is an acute issue,” he said. “Subdistrict No. 1 has a standard, as required by state statute and articulated in their current Plan of Water Management, that is very specific in terms of an aquifer storage level and the need to achieve that level within a specified time.
“While the Subdistrict has taken steps to meet that goal during the last decade, the current drought and the associated reduction in available surface water has impacted the Subdistrict’s ability to recover the aquifer. This is not new information for the members of the Subdistrict and I believe that meeting the current goal within the specified time would require measures more drastic than the Subdistrict anticipated 11 years ago.”
The unconfined aquifer is specific to Subdistrict 1, and it’s the farmers and ranchers in that area of the Valley who have asked Rein and the state Division and Water Resources for more time to meet the state’s sustainability requirements. Subdistrict 1 board of managers recently submitted an amended plan of water management that would see farm operators pumping only the amount of their natural surface water. For farms that have no natural surface water, they would be forced to purchase surface-water credits from a neighboring farm with excess surface water or potentially watch their fields dry up.
“The published data showing levels of aquifer storage in the unconfined aquifer of Subdistrict #1 indicates that the aquifer is not at the level that must be met by 2031 according to Subdistrict No. 1’s current Plan of Water Management,” Rein said. “The Division of Water Resources is in discussion with Subdistrict No. 1 regarding their efforts to achieve sustainability and a revised POWM (Plan of Water Management). To allow for a fair and constructive discussion with the Subdistrict, I will limit my comments at this time to just say that we are developing feedback for their consideration.”
The only other unconfined subdistrict in the Rio Grande Basin is the Trinchera Subdistrict, and “it too is having difficulty with sustainability of the aquifer in its area,” Rein said. “Currently the Trinchera Subdistrict is significantly curtailing the production of wells in order to build the aquifer level back up to a point where full production will again be allowed.”
As for the confined aquifer, Rein said artesian pressures associated with the confined aquifer are currently at levels consistent with the state’s Groundwater Rules for all of the confined aquifer subdistricts except Subdistrict 4, the San Luis Creek subdistrict. Subdistrict 4, he said, is taking steps to reach sustainability by limiting pumping in that area.
“Therefore, at this time, almost all subdistricts are operating in a sustainable environment in regard to the confined aquifer,” he said.
Simpson, who is the general manager of the Rio Grande Water Conservation District, took that to mean “we’re not pumping any more today than we pumped in 1978 to 2000.” The state’s definition for sustainability of the confined aquifer is “allow the pressures in the confined aquifer to exist as they did 1978 to 2000.”
Through the signing of SB22-028, the Groundwater Compact Compliance Fund sponsored by Simpson in the state Senate, another $30 million will be made available to help the Rio Grande Water Conservation District purchase and retire additional groundwater wells to reduce the number of irrigated acres even more. Rein expects Subdistrict 1 to benefit.
“Funding and authorization from SB22-028 is available to help the Subdistrict retire more irrigated acreage that currently relies on groundwater from the unconfined aquifer and the Subdistrict is also considering an amended Plan of Water Management to set a standard and put processes in place to achieve true sustainability. With these positive steps, I’m optimistic that the Subdistrict can successfully address their challenges.”
