Talk about this article...  2022: The Year of Decision? January 01, 2022 New Information Concerning Drought Response Operations Agreement (DROA)
NARRATIVE By end of Year 2022, we may know if management reforms in the Colorado River Basin (CRB) are going to effective, or not. When water management alternatives were presented in 2005 & 2006 to the Bureau of Reclamation during preparation of the EIS called Shortage Criteria, the seven states promised to prevent shortages by making the reservoir storage system perform more efficiently (Basin States Alternative of 2006). This promise began to falter in Year 2013 (archived), was modified in Year 2019, and then failed in Year 2021. In Year 2007, this unfortunate outcome was expected and documented by cautionary scientists and NGOs.
Background Materials
With total reservoir storage in the CRB currrently at 38% (32% as of July 15, 2022, see table below), a too-close-for-comfort situation has indeed occurred. When the total reservoir system drops below 30 percent, and various hydropower and water contracts begin to default, the water managers will be in a position of defeat. They should feel awful about jumping the guard rails for the law of the river—but they do not. They won't, or can't, turn off their auto-pilot switches for developing new water projects, otherwise known as feeding the boom and bust cycle (1985 - OpEd by Wallace Stegner). CURRENT RESERVOIR STORAGE LEVELS (Live Storage)As of July 15, 2022
The public laws designed to reclaim the arid lands of the western United States may yet go down as the largest failed social experiment in American history. How we walk away from this situation is yet to be determined, but this much we do know, the limits of nature have been exceeded and all the expectations of the 1928 Boulder Canyon Project Act became serious miscalculations. As it stands today, these communities dependent on good water governance are in a position of vulnerability, rather than sustainibility. Change must prevail. Splitting the basin into lower and upper divisions was the biggest blunder of the negotiations for the Colorado River Compact of 1922 and exceeding the limitations of geography and climate is why. Equity and sound planning will not happen in either division until the limitations of this geography and climate are properly defined for what they are, and are not. This is exactly what John Wesley Powell asked of Congress in his professional narratives submitted between 1875 to 1893. Ignoring geography and climate is why system failure exists in the Colorado River Basin. How this is accomplished is actually quite simple: work with nature and demonstrate some respect for the gifts we did not create. ### NEWS AND OPINION ABOUT RESPONSES TO CLIMATE DISRUPTION
DROUGHT RESPONSE OPERATIONS AGREEMENT (DROA) The Upper Basin DROA is a plan to make a plan at the last minute about emergency dam operations at Glen Canyon Dam, and to prevent the cessation of hydroelectric power generation, and how these operations will change the downstream, aquatic ecology of Grand Canyon National Park. Comments will be accepted through Thursday, Feb. 17, 2022, and can be submitted by: Email at: droa@usbr.gov Or by mail to: Public Review Documents ADDITION INFORMATION ABOUT THE PROPOSED FIX The fix is to increase releases from Flaming Gorge Dam on the Green River and to reduce releases from Glen Canyon Dam. The total amount of water that will stabilize the elevation of Lake Powell is 1 million acre-feet, which essentially buys about two months of modified hydroelectric production at Glen Canyon Dam.

1965 Inspection: Photo of cavitation damage to turbine at Glen Canyon Dam
During the initial filling of Lake Powell, and while finishing the various components of the hydroelectric powerhouse at the base of Glen Canyon Dam, a turbine was pulled and inspected for damage caused by cavitation (water vapor implosions). In 1964 and 1965 the reservoir elevation was stabilized at the minimum power pool elevation of 3490 feet. The photograph below highlights the damage caused by cavatation to the runners (blades) of the turbine. At low reservoir elevations vortices will appear at the intakes of the water outlet works, which introduces air into the water column flowing through the pipes that spin the generators.
