Water supply forecast volumes decreased across most of the region, Moser said during the webinar. Hourly releases during February 2023 will fluctuate from a low of approximately 5,797 cfs during the early morning hours to a high of 10,091 cfs during the afternoon and evening hours. 15 Day Weather Forecast "We might get lucky with the weather, but the idea of the system recovering is really hard unless you reduce water use in that basin," Lund told Newsweek.

Based on current inflow forecasts, the current projected end of water year 2023 total Colorado Basin reservoir storage is approximately 20.93 maf (36 percent of total system capacity). Last week, the Bureau of Reclamation announced extraordinary action to keep the water level at Powell from dropping too low, which could threaten hydropower production at Powells Glen Canyon Dam. In the image acquired on May 1, 2004, the reservoirs northwestern branch is isolated from the main reservoir; the shallow water upstream could not crest raised areas in the lakebed. With low-runoff conditions and . The deep, narrow, meandering reservoir extends upstream into southern Utah. The forecast is changing daily and there are still a lot of variables, said Lisa Meiman, a spokeswoman for WAPA.

The 30-year average was updated in October 2022 from 1981 through 2010 to 1991 through 2020. It wasnt just the Powell number that dipped, although the amount of runoff that makes its way to Powell each year is considered a good barometer for conditions basinwide. Some Arizona cities have implemented drought management plans to conserve water, but the area continues to use water at a rate that negates Lake Powell's recovery. Additionally, there are possible inflow scenarios that would result in reservoir elevations falling outside the ranges indicated in these reports. Lund said he expects water use in the basin to have "capped out," but the reservoir can't continue to supply water at the pace in which the area consumes it. The Glen Canyon Dam annual release has initially been set to 7.00 maf, and in April 2023 Reclamation will evaluate hydrologic conditions to determine if balancing releases may be appropriate under the conditions established in the 2007 Interim Guidelines; Balancing releases will be limited (with a minimum of 7.00 maf) to protect Lake Powell from declining below elevation 3,525 feet at the end of December 2023; Balancing releases will take into account operational neutrality of the 0.480 maf that was retained in Lake Powell under the. and last updated 5:24 PM, Sep 24, 2021. Even in low emission climate scenarios (forecasts that are based on the assumption that future carbon dioxide emissions will increase relatively slowly), models predict precipitation may decline by 20-25 percent over most of California, southern Nevada, and Arizona by the end of this century.

This was the lowest water levels have been since the lake was first constructed in the 1930s. In addition to the February 2023 24-Month Study based on the Most Probable inflow scenario, and in accordance with the Drought Response Operational Agreement (DROA)), Reclamation has conducted model runs in February to determine a possible range of reservoir elevations. From there, a swing to the northeast delivers boats into Lake Powell's main artery. a greater portion of the future hydrologic and climatic uncertainty becomes known and Official Glen Canyon National Recreation Area Changing Lake Levels Info. On Tuesday, the lake fell below 3,525 feet above sea level, a key target elevation that water managers have been trying to keep Powell above because it provides a buffer from the minimum level at which Glen Canyon Dam can generate power. This level is actually .02 feet . Under the current most probable forecast, the total water year 2023 unregulated inflow to Lake Powell is projected to be 10.44 maf (109 percent of average). This is a decrease of 3.33 maf over the total storage at the beginning of water year 2022 when total system storage was 22.87 maf (39 percent of capacity). levels.

Lukas noted that the dry soil conditions are factored into the NOAA runoff predictions from the get-go so there shouldnt necessarily be any big surprises with that particular variable. In the early 21st century, this modern marvel of engineering faced an ancient enemy: prolonged drought in the American Southwest. In order to restore Lake Powell's levels, one expert said people must conserve water in the Colorado River's lower basin. Note that projections of elevation and storage for water year 2023 have significant uncertainty at this point in the season. The Bureau of Reclamation's most recent projections show Lake Mead dropping to 1,033.4 feet in elevation by the end of 2023, about 14 feet lower than the reservoir's current level. She reported that, as of March 16, 2022, Lake Powell was at an elevation of 3,524.83 feet (ft.) with storage of 5.916 million acre-feet (maf) or 24 percent of capacity.

But the declining water already has drained some of the fun, he said. Because the 2022 operations were designed to protect critical elevations at Lake Powell, Reclamation will implement Lower Elevation Balancing Tier operations in a way that continues to protect these critical elevations, or preserves the benefits of the 2022 operations to protect Lake Powell, in water year 2023. The August 2022 24-Month Study modeled 2023 and 2024 operations at Lakes Powell and Mead as if the 0.480 maf had been delivered to Lake Mead for operating tier/condition purposes both for the U.S. Lower Basin and for Mexico. The system is appreciated for the water it supplies, but criticized for the environmental problems and cultural losses that have resulted from its creation. Detailed Map of Powell In July 2022, the lake reached a historic low of 1,040 feet above sea level. . "Its always good to plan for the worst, right?

"This is probably the largest reservoir system in the country in terms of storage. Precipitation was better, but still slightly below normal in the Upper Colorado River Basin. The unregulated inflow volume to Lake Powell during January was 361 thousand acre-feet (kaf) (107 percent of average). Releases from Glen Canyon Dam can also fluctuate beyond scheduled releases when called upon to respond to unscheduled power outages or power system emergencies. At the beginning of water year 2023, total system storage in the Colorado River Basin was 19.54 maf (33 percent of 58.48 maf total system capacity). Precipitation declines combined with booming urban populations will present a significant challenge to Western water managers in the near future. google_ad_channel ="2397569894"; google_ad_height = 600; The Bureau of Reclamation announced on May 3, 2022, two separate urgent drought response actions that will help prop up Lake Powell by nearly 1 million acre-feet (maf) of water over the next 12 months (May 2022 through April 2023). Differences between the full period forecasts and the residual forecasts may not exactly equal the actual observed volumes due to rounding conventions (see Definitions section). //-->, Printable Version Under a Drought Contingency Plan adopted in 2019, approximately 500 thousand acre-feet (kaf) of water will come from Flaming Gorge Reservoir, located approximately 455 river miles upstream of Lake Powell. Upper Colorado River Basin regularly experiences significant year to year hydrologic variability. Despite those releases, Powell dropped below 3,525 last month, hitting 3,523, another historic drought landmark.
