NEVADA RESERVOIR REPORT

Last Updated: January 1, 2026

In the latest report on Nevada’s dams and reservoirs, there have been notable fluctuations in storage levels as observed in the most recent dataset. Topaz Lake near Topaz is currently showing water levels above the average at an elevation of 93 feet, which is higher than the average of 87.77 feet. Similarly, Wild Horse Reservoir near Gold Creek is reporting levels above the average, with a current elevation of 6195 feet compared to the usual 6191.94 feet. On the other hand, Marlette Lake near Carson City is experiencing significantly lower water levels, with a current elevation of just 16 feet against an average of 36.09 feet. Lake Mead, a major water source, is also displaying a concerning decrease in storage, holding only 8,591,572 acre-feet of water, starkly lower than the average storage of 17,987,579 acre-feet.

These anomalies in water levels can be attributed to the state’s recent weather patterns and external environmental factors. While the late storms have been a relief for the state’s snowpack, as noted in various reports, it appears they have not been sufficient to normalize the reservoir levels, particularly for Lake Mead, which is substantially below average levels. Marlette Lake’s drastically low levels may indicate a localized issue or a more extensive drought impact. Meanwhile, the increased levels in Topaz Lake and Wild Horse Reservoir suggest that the late-season precipitation has positively impacted some areas. In the broader context, as highlighted by sources like The Mercury News, California and Nevada continue to need more snow accumulation to secure water supplies for 2026, with current conditions potentially exacerbating wildfire risks and water scarcity.

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.
