ARIZONA RESERVOIR LEVELS

March 6 2025
       

In Arizona, where water is a precious commodity, the state of reservoirs and dams holds significant implications for water management and conservation. Latest observations reveal a mixed picture, with some water bodies experiencing levels that defy the typical expectations for this time of year. The iconic Lake Powell at Glen Canyon Dam, for instance, stands at a water surface elevation of 3564 feet, trailing behind its average of 3570.96 feet. This indicates a condition that could be related to lower snowpack levels or reduced river inflows, marking a concern for the region's water supply. Conversely, the San Carlos Reservoir at Coolidge Dam, with its current storage at a robust 152,600 acre-feet, surpasses its average storage of 116,636.4 acre-feet, suggesting an abundance that may be due to recent precipitation events or strategic water management practices.

Delving into the specifics, it's evident that certain reservoirs are bearing the brunt of aridity more than others. The Blue Ridge Reservoir near Pine is recording a gage height of 44 feet, significantly lower than its average of 71.43 feet, which underscores the impact of prolonged dry conditions in the region. Lake Mohave at Davis Dam, however, presents a different story with a gage height of 42 feet, slightly above its average of 40.95 feet – a sign of adequate inflow or possibly controlled releases from upstream facilities. The storage in Lake Powell reflects a stark decrease at approximately 7,945,911 acre-feet, which is nearly half of its average storage capacity of 14,785,140.42 acre-feet, signaling a long-term trend of water scarcity that could affect hydroelectric power generation and water allocations downstream. In contrast, Lake Mohave's storage exceeds its average, illustrating a current surplus that benefits recreational use and wildlife habitats. These discrepancies among Arizona's reservoirs emphasize the intricate balance of water management and highlight the need for continued monitoring and adaptive strategies to address the varying conditions dictated by climate variability and human demands on water resources.
