WYOMING RESERVOIR LEVELS

April 15 2025
       

Wyoming's reservoirs and dams are crucial for water storage and management within the state. As of the latest observations on April 15, 2025, there are variances in storage levels when compared to historical averages. For example, the Big Sandy Reservoir near Farson has a slightly elevated water surface elevation, standing at 6753 feet versus the average of 6748.11 feet. This minor increase might not significantly impact operations. In contrast, the more concerning situation is at Fontenelle Reservoir, which is considerably below its average storage level of 204,593.07 acre-feet, with a current storage of only 132,009 acre-feet. This represents a significant deficit in water availability and may indicate an abnormal condition.

Additionally, Big Sandy Reservoir shows an abnormal increase in storage, from an average of 20,132.44 acre-feet to a current storage of 27,728 acre-feet, suggesting higher inflows or decreased outflows. Meeks Cabin Reservoir and Eden Reservoir are also experiencing variations, with the former below its average storage by approximately 3,193 acre-feet and the latter above its average by about 984.4 acre-feet. These discrepancies may be related to current snowpack levels, river flows, and regional climate conditions.

Cross-referencing data from sources such as Inside Climate News indicates that new stream gauges and weather stations are set to help tribes in Wyoming endure flooding and drought, suggesting that there is an ongoing concern for extreme weather and its impact on water resources. In northern Nevada, snowpack is reportedly in good shape, which could have a positive influence on downstream flows into Wyoming, whereas southern parts are set for a 'lean water year.' This contrast hints at the variability of water conditions across the region. Moreover, initiatives like recycled toilet water, mentioned in Nevada Current, underscore the increasing need for innovative water management solutions in western states, which might become relevant for Wyoming as well if current trends continue. Reports from chadronradio.com on runoff estimates for growers imply that agricultural water usage may also be impacting reservoir levels. Overall, while some reservoirs are near average levels, others like Fontenelle indicate possible concerns for water supply in Wyoming, with abnormal conditions potentially tied to regional snowpack variations and river flow patterns.
