NEVADA FLOW REPORT

Last Updated: December 26, 2025

Nevada's river systems, particularly in the northern region, are exhibiting varied streamflow patterns that are crucial for water enthusiasts to note. One of the most significant observations is the Truckee River, which shows substantially higher than normal flows, with readings near Sparks and Reno reaching over three times the typical flow at 2100 and 1970 cubic feet per second (cfs) respectively, and gage heights of 7.75 and 6.87 feet, indicating a potential for exciting whitewater conditions but also a risk of flooding if trends continue. Contrastingly, the Colorado River below Davis Dam and Las Vegas Wash near Henderson report flows below normal, at -18.04% and -19.45% respectively, which could impact water activities and local ecosystems.

The Carson River basin also presents noteworthy fluctuations, with the Carson River near Fort Churchill showing an exceptional increase in flow at 1200 cfs, a dramatic 360.02% above normal, and a gage height of 4.06 feet, which could suggest emerging flood conditions or a boon for rafting if safety permits. Yet, the East Fork Carson River near Gardnerville is closer to normal flow at 138.14%, signaling reliable conditions for river activities. These variations are essential for communities like Reno, Sparks, Carson City, and other surrounding areas, as they may affect water supply, recreational opportunities, and environmental health. Users such as whitewater enthusiasts navigating the Truckee or East Fork Carson rivers should be mindful of the substantial increases in streamflow, while those near the Las Vegas Wash may encounter lower than usual water levels, affecting the navigability and aquatic habitat.

       



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 26 2025

Residents of Nevada, particularly those in the Greater Reno-Carson City-Minden Area and the Spring Mountains, are urged to exercise caution as a series of weather advisories are in effect. Heavy snowfall is expected, with accumulations of 2 to 6 inches above 5500 feet, potentially reaching up to 8 inches on ridges, and 8 to 16 inches in the Spring Mountains above 7500 feet. Slick, hazardous road conditions may impede morning commutes and travel could become very difficult to impossible in the affected regions. Additionally, gusty winds across the state, with gusts reaching 40 to 50 mph and up to 65 mph along ridges, may cause blowing dust, reduced visibility, and the risk of downed tree branches. Blowing dust in White Pine County could also reduce visibility. High profile vehicles may face travel difficulties due to these conditions. Residents should prepare for potential power outages and stay informed on the latest weather updates.
