Reservoir report
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.

Reservoir FAQ
About Utah dams & reservoirs
Where does the Utah dam data come from?
The U.S. Army Corps of Engineers National Inventory of Dams (NID) plus state water-resource agencies. Snoflo joins these public records with live USGS streamgauge readings downstream where available. The NID is the canonical federal dam registry.
What does Hazard Potential mean?
USACE classifies every dam by what would happen if it failed: Low (no loss of life expected, minimal economic damage), Significant (no loss of life but economic, environmental, or lifeline damage), High (loss of life expected). It's a downstream-consequence rating, not a likelihood of failure.
What is Normal Storage in acre-feet?
The volume of water the reservoir holds at its normal operating level, measured in acre-feet. One acre-foot is about 325,851 gallons or 1,233 cubic meters — the amount needed to cover one acre to a depth of one foot.
Why are some Utah dams missing storage or height data?
USACE NID records can have gaps for small or older dams that pre-date federal reporting requirements. Snoflo surfaces whatever the canonical record contains. If a dam you care about has incomplete data, contact the operating agency or USACE for updates.
Can I see live water levels?
Yes — tap any dam name to open its detail page, which pulls live storage data from USGS streamgauges or operating-agency feeds where available. Historical levels and seasonal averages are also shown.
Why does Utah have so many dams?
The U.S. has over 90,000 dams — most built between 1930 and 1980 during the federal water-development era. Utah's count reflects a combination of agricultural irrigation needs, flood control, hydropower, and recreation. The "Built by decade" chart above shows the timeline.
