January 13, 2021 Executive Director's Report
EXECUTIVE DIRECTOR’S REPORT TO THE COLORADO RIVER BOARD OF CALIFORNIA January 13, 2021 COLORADO RIVER BASIN WATER SUPPLY CONDITIONS REPORT As of January 4th, the surface water elevation at Lake Powell was 3,581.80 feet with 10.1 million- acre feet (MAF) of storage, or 42% of capacity. The surface water elevation at Lake Mead was 1,083.89 feet with 10.34 MAF of storage, or 40% of capacity. As of January 3rd, the total system storage was 27.50 MAF, or 46% of capacity, which is about 3.8 MAF less than the total system storage at this same time last year. As of January 6th, the Upper Basin reservoirs, excluding Lake Powell, ranged from 53% of capacity at Fontenelle Reservoir in Wyoming; 84% of capacity at Flaming Gorge Reservoir in Wyoming and Utah; 92% of capacity at Morrow Point, and 48% of capacity at Blue Mesa Reservoir in Colorado; and 63% of capacity at Navajo Reservoir in New Mexico. As of December 16, 2020, the forecasted unregulated inflow into Lake Powell for Water Year (WY) 2021 is 6.23 MAF (58% of normal). The forecasted April through July 2021 runoff into Lake Powell for Water Year-2021 is 4.05 MAF (57% of normal). For WY-2021, the November observed Lake Powell inflow was 0.26 MAF (55% of normal), and the December Lake Powell inflow forecast is 0.21 MAF (58% of normal). To date, WY-2021 precipitation is 65% and the current basin snowpack is 75% of normal. Colorado Basin River Forecast Center Webinar On January 8th, the Colorado Basin River Forecast Center (CBRFC) held a webinar to review the Basin’s current water supply conditions and forecasts. -

River Flow Advisory
River Flow Advisory Bureau . of Reclamation Upper Colorado Region Salt Lake City, Utah Vol. 15, No. 1 September 1984 River flows in the Upper Colorado River drainage, still high for this time of year, are not expected to decrease much for several weeks: While the daily update of operations and releases has been discontinued, the toll-free numbers now provide updates on Bureau of Reclamation activities and projects. Utah residents may call 1-800-624-1094 and out-of-Utah residents may call 1-800-624-5099. Colorado River at Westwater Canyon The flow of the Colorado River on September 10 was 7, 000 cfs, and is expected to decrease slightly over the next few weeks. Cataract Canyon Includin2 the Green- River The flow was 11,500 cfs on September 10 and will continue to decrease slightly. Lake Powell Lake Powell's elevation on September 10 was 3,699. Assuming normal inflow for this time of year, the lake should continue to go down slowly to elevation 3,682 by next spring. Colorado River through Grand Canyon . Releases through Glen Canyon Dam remain at 25,000 cfs. These releases are expected to be maintained with no daily fluctuations in river flows. Upper Green River - Fontenelle Reservoir Fontenelle Reservoir is now at elevation 6,482 feet. Releases through the dam will be reduced to about 600 cfs starting on September 17 for about 2 weeks during powerplant maintenance. Green River Flows Below Flaming Gorge Dam On September 10 Flaming Gorge Reservoir was at elevation 6,039.9 feet. Releases from the dam are expected to average 2, 500 cfs in September and October with usual daily fluctuations. -

An even lower runoff forecast is avoided only by the presence of above normal snow accumulations in the high mountains. Another milestone was reached lost month in the uti lization of water of the Colorado River in the Upper Basin . On Thursday night, Moy 29, 1969, water stored in Lake Powell reached elevation 3570 feet, which is "roted head" for the powerplont located at the toe of Glen Canyon Dom . "Roted head" is the lowest level at which water flowing through the turbines con drive the generators at their nameplate capacity. With normal rai nfall, it is expected that Lake Powell 's water surface should reach on all-time high in July at about elevation 3580 feet with a live storage of about 10,290,000 acre-feet. Planned releases from Lake Powell for water year 1969 ore about 8 . 8 million ocre feet. For the next 3 years thereafter annual releases should be near this amount in order to deliver Colorado River Compact requirements to the Lower Basin. The entire release wi 11 be used to generate power for power customers in both the Upper and Lower Bosi ns. -

The facilities are known collectively as the Salt Lake City Area Integrated Projects (SLCA/IP) and include dams equipped for power generation on the Colorado, Green, Gunnison, and Rio Grande rivers and on Plateau Creek in Arizona, Colorado, Utah, Wyoming, and New Mexico. Of these facilities, only the Glen Canyon Unit, the Flaming Gorge Unit, and the Aspinall Unit (which includes Blue Mesa, Morrow Point, and Crystal dams) are influenced by Western power scheduling and transmission decisions.
