NEVADA FLOW REPORT

Last Updated: December 24, 2025

Nevada's streamflow landscape presents a varied picture for river and water enthusiasts looking to understand seasonal trends and the potential for abnormal streamflow events. The Truckee River, a significant waterway for both ecosystems and recreation, especially near populous areas like Reno and Sparks, is currently experiencing higher-than-normal streamflows, with the Truckee River near Mogul flowing at 1350 cubic feet per second (cfs), a substantial 199.13% of the normal flow, and similarly elevated figures downstream through Reno, Sparks, and toward Nixon. Contrastingly, key points along the Colorado River and Las Vegas Wash reflect below-normal streamflows, with the Colorado River Below Davis Dam running at a reduced flow of 5050 cfs, 18.04% below what's typical for this season.

Areas around Henderson may take note of the Las Vegas Wash, where the streamflow near Pabco Road is slightly below normal at -17.02%, and enthusiasts near Boulder City can observe the Las Vegas Wash below Lake Las Vegas with a flow slightly above the norm. In the Carson and East Fork Carson Rivers, streamflows are variable, with the Carson River near Fort Churchill showing a high 266.21% of the expected flow, indicating a potential alert for local communities and those using the waterways for activities such as kayaking or fishing. On the other hand, the Walker River, important for both agriculture and wildlife, shows mixed conditions, with some sites like above Little Dam near Schurz reporting flows at 182.02% of normal. This report should guide enthusiasts on where to find vigorous currents for whitewater activities or calmer waters for leisurely pursuits, while remaining vigilant for any rapid changes that might indicate flood risks or flow droughts in their areas of interest.

       



Nevada's climate is arid and semi-arid, with most precipitation occurring as snow in the mountains during the winter months. Major surface flows include the Humboldt River, Truckee River, and Walker River, which are heavily managed and regulated due to their importance for agriculture and urban water supplies. Major reservoirs/dams include Lake Mead, Lake Tahoe, and the Hoover Dam. Nevada's hydrology is heavily influenced by its geology, with a high degree of groundwater storage and limited surface water availability. Snowpack data is critical for water management, with the majority of the state's water supply coming from snowmelt. The Colorado River Basin also plays a significant role in Nevada's water resources, with the state receiving a portion of its allocation from the basin.


       

Winter Storm Warnings

December 24 2025

Residents of Nevada, particularly those in Esmeralda, Central and Northeastern Nye, Lincoln, Southern Lander, Southern Eureka, and parts of Elko County, are urged to exercise caution as Flood Watches and Wind Advisories are in effect. The National Weather Service has warned of possible flooding due to excessive rainfall and strong south winds reaching 20 to 30 mph with gusts up to 50 mph. These conditions may result in downed tree limbs, power outages, and reduced visibility due to blowing dust, especially around Highway 95 and Highway 93. Please stay informed, prepare for potential emergencies, and avoid unnecessary travel in the affected areas.
