By, What We Know, And What You Can Do To Help. Consistent with Section 6.D.1 of the Interim Guidelines, Lake Powells operations in water year 2023 are governed by the Lower Elevation Balancing Tier (LEBT) with an initial projected water year release volume of 7.00 maf. Lake Mead was at elevation 1,064.30 ft. with storage of 8.753 maf or 34 percent of capacity. Global warming is expected to make droughts more severe in the future. "As a result of this update, the median water year 2022 inflow forecast into Lake Powell decreased by 800,000 acre-feet," USBR stated in a press release distributed Thursday.

The probable maximum inflow scenario reflects a wet hydrologic condition which statistically would be exceeded 10 percent of the time. monthly forecasts become more accurate. endstream endobj 160 0 obj <>/Metadata 41 0 R/Pages 157 0 R/StructTreeRoot 59 0 R/Type/Catalog/ViewerPreferences 177 0 R>> endobj 161 0 obj <>/MediaBox[0 0 792 612]/Parent 157 0 R/Resources<>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI]/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 162 0 obj <>stream Among the dams on the Colorado is Arizona's Glen Canyon Dam, which creates Lake Powell. 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. Water supply forecasts take into consideration present hydrometeorological conditions and use The unregulated inflow volume to Lake Powell during January was 361 thousand acre-feet (kaf) (107 percent of average).

Lake Powells water levels plummeted in early 2005, according to the U.S. Department of the Interior Bureau of Reclamation. For five years after 2012, snow- and rainfall totals were generally low, as the region suffered through a persistent, long-term drought. Lake Powell
