Reservoir report

Nevada's major reservoirs and dams include Lake Mead, Lake Tahoe, and Hoover Dam. Lake Mead is the largest reservoir in the US and is fed by the Colorado River, while Lake Tahoe is fed by the Truckee River. Snowpack in the Sierra Nevada Mountains is a major source of water for these reservoirs. In recent years, drought conditions have led to record-low levels in Lake Mead, causing concerns about water shortages for the surrounding states. Seasonal trends include lower water levels in the fall and winter months, with spring snowmelt providing a boost in water supply. Overall, the hydrology in Nevada is heavily dependent on snowpack and the management of water resources is crucial to ensure sustainable use in the face of changing climate conditions.

Reservoir FAQ

About Nevada dams & reservoirs

Where does the Nevada 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 Nevada 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 Nevada have so many dams?

The U.S. has over 90,000 dams — most built between 1930 and 1980 during the federal water-development era. Nevada's count reflects a combination of agricultural irrigation needs, flood control, hydropower, and recreation. The "Built by decade" chart above shows the timeline.
