Lake Powell Loses 40,000 Acre-Ft of Water

The Colorado River is in bother, and has been for many years. It’s overextended, and even with back-to-back stellar water years, it’s nonetheless in unhealthy form. That’s why the current information about an unintended launch of 40,000 acre-feet of water from the Higher Colorado River Basin is worrying, to say the least.

Based on Jerd Smith of Contemporary Water Information, Bureau of Reclamation officers confirmed that an unintended 40,000 acre-feet of water was discharged from Lake Powell between 2021 and 2022. That was a time of crucial water ranges at Lake Powell that threatened the reservoir’s means to generate energy. To mitigate that, releases have been despatched upstream from Flaming Gorge and Blue Mesa reservoirs. As that water arrived, it needed to be pushed by Powell into Lake Mead for energy technology, and to stability the water ranges between these two reservoirs. That’s when an additional 40,000 acre-feet of water left Powell, which implies it formally left the Higher Colorado River Basin. And in response to Smith’s reporting, there aren’t any plans to revive that misplaced water to the Higher Basin.

“Underneath the 2007 Interim Tips, this was the primary time Reclamation balanced the contents between lakes Powell and Mead in close to real-time, working in opposition to rapidly altering hydrology over the course of just some months,” Alex Pivarnik, supervisory hydrologist with Reclamation’s Higher Colorado Basin Area, mentioned in an emailed assertion to Smith. “Getting it inside 0.5% is fairly outstanding, given the circumstances,”

40,000 acre-feet is sufficient water to serve 80,000 homes for one to 2 years, in response to Smith. So, whereas it’s not an enormous quantity of water compared to the whole Colorado River, it’s nonetheless a major mistake.

This information comes as Higher and Decrease Basin states are preventing over new working guidelines for the Colorado River, as the present guidelines expire in 2026. Higher Basin states desire a bigger share of their water, whereas Decrease Basin states, together with California, are reluctant to surrender their shares.
