WYOMING RESERVOIR REPORT

Last Updated: December 24, 2025

Wyoming's reservoirs play a critical role in water storage and management for the region. The latest observations indicate a mix of average and below-average storage levels that are cause for attention. The BIG SANDY RESERVOIR NEAR FARSON shows a slight decrease in water surface elevation, reporting a current level of 6745 feet compared to the average of 6748.17 feet. FONTENELLE RESERVOIR, a significant water source with an average storage capacity of 204,842 acre-feet, is currently at 190,978 acre-feet, hinting at a notable shortfall. Similarly, BIG SANDY RESERVOIR and MEEKS CABIN RESERVOIR report storage levels well below their respective averages, with BIG SANDY at 15,803 acre-feet (average 20,180.23) and MEEKS CABIN at a stark low of 5,007 acre-feet (average 14,001.91). EDEN RESERVOIR is also experiencing reduced levels at 1,938 acre-feet, substantially lower than its average of 5,399.88 acre-feet. These figures, last observed on December 24, 2025, highlight a concerning trend in water availability.

In cross-referencing these findings with additional sources, it becomes evident that regional climate challenges contribute to these abnormal conditions. The Reno Gazette Journal reports ongoing struggles among states to compromise on the Colorado River amidst a water shortage, directly impacting Wyoming. Considering that reservoir levels are dependent on river inflow and snowpack, such disputes and shortages may exacerbate the already lower-than-average readings. Moreover, research advancements from a University of Wyoming student, as covered by the High Plains Journal, could provide insights into climatic factors affecting these water bodies. Current storage levels are indicative of broader environmental stressors, including reduced snowpack and altered river flows, which are essential for reservoir replenishment. As such, Wyoming's major dams and reservoirs could face significant management challenges in the near future, necessitating careful monitoring and collaborative water management strategies.

Wyoming has numerous reservoirs and dams that play a critical role in supplying water for irrigation, municipal, and industrial purposes. Some of the major reservoirs in the state include Boysen, Flaming Gorge, Glendo, and Pathfinder. These reservoirs rely on streamflow from various sources, including the North Platte, Green, and Snake Rivers. Snowpack and mountain precipitation are vital to the water supply in these areas, with most reservoirs being fed by snowmelt during the spring and summer months. In recent years, Wyoming has experienced drought conditions, which have affected the water levels in its reservoirs. For example, in 2018, the Flaming Gorge Reservoir recorded its lowest level in over 50 years. Seasonal trends also play a role in the hydrology of the area, with water levels typically peaking in early summer and gradually decreasing throughout the fall and winter months. Despite these challenges, Wyoming's reservoirs and dams continue to provide essential water resources for the state's residents and industries.
