NEVADA RESERVOIR REPORT

Last Updated: December 5, 2025

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.
