The latest publication from the Center for Colorado River Studies looks back at the 2024 runoff season (mid-April to early July), observing that the basin netted only a modest bump in storage of 2.5 maf, a significant volume but much lower than the unusually wet 2023 season. However, combined with effective Upper Basin strategies to limit consumptive use of last year’s abundant runoff, net basin-wide storage increased slightly year over year.

Study Offers an Environmental and Economic Argument in Defense of Flood Irrigation Anonymous (not verified) Thu, 06/13/2024 - 00:00

New research from a team at the University of Wyoming (including the CRRG’s Kristi Hansen) suggests that flood irrigation in shallow alluvial aquifers can have significant economic benefits in the Upper Green by creating return flow regimes benefitting the brown trout sport fishing economy. The work highlights the complicated site-specific relationship between efforts in agricultural water-use efficiency, and the protection of environmental and economic objectives.

Colorado River Research Group Members Offer Post-2026 Alternative Anonymous (not verified) Tue, 04/16/2024 - 13:13

Doug Kenney

Colorado River Research Group (CRRG) members Jack Schmidt, Eric Kuhn and John Fleck submitted an “alternative” to the post-2026 EIS process entitled: “Managing the Powell/Grand Canyon/Mead ecosystem after 2026.” In a nutshell, the alternative suggests that the Secretary of Interior be empowered to employ an adaptive management approach allowing releases from Powell to Mead to “be optimized to meet environmental, recreational, and cultural goals while retaining an interstate accounting system that still meets water-supply objectives.”

Water Year 2023 in Context: A Cautionary Tale

Jack Schmidt

Water Year 2023 was exceptional for runoff and for boosting reservoir storage---but it isn't likely to repeat itself for the additional 3-6 years needed to refill the reservoirs to 1999 levels (the last time they were full). We need to work to conserve the gains of WY2023, as history shows that extra storage from wet periods is generally completely consumed within two years.

“Unprecedented,” said Jason Robison, a professor of natural resources law at the University of Wyoming. “Two to four million acre feet in conservation saving blows the doors off of anything that has been done since the onset of the megadrought in 2000.”
