By Jack Schmidt Unfortunately, water use between now and next April is on track to exceed the inflows of the snowmelt season, resulting in a net loss of reservoir storage. The persistent decrease in runoff is severely challenging the quest to rebuild reservoir storage. Summary Reservoir storage in the Colorado River basin is now …

A federal judge this week criticized the federal government for failing to consider the risk of a Colorado River Compact call in its environmental review of the planning for Denver Water’s expansion of Gross Reservoir in Boulder County. Wrangling over the risk of a compact call – which the judge said could force water use …

The Middle Rio Grande Conservancy District Board this afternoon (Monday Oct. 14, 2024) approved an agreement among the District, the Albuquerque Bernalillo County Water Utility Authority, and the Bureau of Reclamation for temporary storage of District water in Abiquiu Reservoir on the Rio Chama while El Vado Reservoir is out of comission. This is a …

Update: Data here is from USDA, the “USGS” in the graphs is a typo in the code I used to generate them, which I’m too lazy to fix. The U.S. Department of Agriculture’s 2024 estimate of alfalfa acreage in New Mexico, 130,000 acres, is the lowest it’s been since the 1950s. Acreage is down 55 …
The Arizona Department of Water Resources has published a thoughtful and also delightfully testy response to Enduring Solutions on the Colorado River, the white paper Kathryn Sorensen et al. (I’m one of the et alias) published in August. First a reminder of our core premise: As we work to reduce water use on the post-2026 …
Water resources must be governed before they can be managed, and the crafting of governance institutions is an ongoing challenge of the human condition. Institutional artisanship requires the availability of tools for institutional design and creation, and a reflective understanding of the use of those tools. Yet neither the tools nor the understanding exist in …
Sept. 30 marks the end of the “water year,” an accounting milestone that gives us an opportunity to take stock. The change in total water storage year-over-year is one way to do this, to help understand if we took more water out of the reservoirs than the climate put in. The graph above is …
Two years ago, when the level of Lake Mead was hovering near elevation 1,040, my artist wife Lissa Heineman and I drove out over UNM’s fall break to see it for ourselves. Out beyond the old Boulder Harbor, we walked a half mile across mud flats to get to the water. I could look out …
By Jack Schmidt The decrease in reservoir storage following the 2024 inflow season has been thankfully modest, but not as favorable as it was at this time last year. Perseverance reducing consumptive uses and losses is needed for reliability and security in the water supply and to regain reservoir storage. Between mid-April and early July …

Taming the Lower Basin Structural Deficit The federally funded water use reductions approved last month by the Imperial Irrigation District and the federal government have made their way into the Bureau of Reclamation’s annual forecast model (updated Sept. 6 as I’m writing this), and the numbers are remarkable. Imperial’s projected 2.2 million acre foot take …
