UTAH RESERVOIR REPORT

Last Updated: December 27, 2025

In Utah, the latest data on reservoir and dam storage levels indicates mixed conditions across the state's water storage systems. Notably, Flaming Gorge Reservoir is reporting above-average storage at 2,994,774 acre-feet compared to its average of 2,915,124.72 acre-feet, which could be beneficial for water supply management. However, Trial Lake and Willard Bay Reservoirs are experiencing considerably low storage levels, with Trial Lake at just 347 acre-feet compared to an average of 946.79 acre-feet, and Willard Bay at 81,382 acre-feet versus its average of 135,497.88 acre-feet. These deviations from normative levels could significantly impact local ecosystems and water availability.

The abnormal conditions at some reservoirs may be connected to broader environmental factors. For instance, the CBS News report highlights widespread water use issues within the Colorado River basin, which could be influencing the storage at Flaming Gorge Reservoir. Moreover, the anticipated snowfall reported by KUTV may potentially alleviate some of the lower-than-average storage levels, particularly for reservoirs relying on snowpack runoff. However, Park City's TownLift notes the second-warmest December on record for Salt Lake, suggesting that reduced snowpack could be a factor in the lower storage levels observed at reservoirs such as Trial Lake and Willard Bay. This snapshot of Utah's reservoirs underscores the need for continued monitoring and strategic water resource management in the face of changing environmental conditions.

Utah has over 100 reservoirs and dams, many of which are used for irrigation, hydroelectric power, and recreation. Major reservoirs in the state include Lake Powell, Flaming Gorge Reservoir, and Strawberry Reservoir. Water for these reservoirs comes from streams and rivers, including the Colorado River and its tributaries, the Green River, and the Provo River. Snowpack from the mountains is a significant source of water for these streams and rivers. Utah experiences a semi-arid climate, with hot summers and cold winters. Drought conditions have been prevalent in recent years, leading to low water levels in some reservoirs. However, record snowfall in 2019 helped to replenish some of these reservoirs. Seasonal trends typically see higher water levels in the spring and early summer due to snowmelt, with levels decreasing in late summer and fall. Overall, reservoirs and dams play a crucial role in managing Utah's water resources and supporting various industries and recreational activities.
