NEVADA FLOW REPORT
Last Updated: December 28, 2025
Nevada's streamflow conditions exhibit considerable variability, with some areas experiencing below-normal flows while others are significantly above normal, which could be of interest to water enthusiasts monitoring seasonal trends and flood risks. The Colorado River below Davis Dam is currently flowing at 5,050 cubic feet per second (cfs), a decrease of 3.81 cfs in the last 24 hours, and is at 81.96% of its normal flow, possibly affecting water activities near the dam. Conversely, the Galena Creek at Galena Creek State Park has seen a dramatic increase, with streamflow surging by 202.75 cfs and reaching an impressive 731.23% of its typical flow, which may indicate localized flooding and could be a concern for communities in the vicinity.
The Truckee River, vital for Reno and its surroundings, shows streamflow levels above average, with the Truckee River near Sparks at 919 cfs, 115.73% of its normal flow, and the Truckee River near Tracy at 1090 cfs, just above the normal at 100.2%. This suggests healthy water levels for potential whitewater activities unless levels rise too high. In contrast, sections of the Carson River are experiencing decreased flows, such as the Carson River at Dayton at 679 cfs, 76.25% of normal, hinting at possible flow droughts that could impact water supply and recreation. River watchers and water resource managers should stay informed of these dynamic conditions, as they may influence water-based recreation and local ecosystems across Nevada.
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.
