NEVADA FLOW REPORT
Last Updated: January 6, 2026
Nevada's streamflow conditions reflect a varied landscape of water movement, with several rivers and streams experiencing fluctuations that are of interest to water enthusiasts and those monitoring water resources. In the Las Vegas area, the Las Vegas Wash at Pabco Road near Henderson reports a minor decrease in streamflow of 5.87 cubic feet per second (cfs) from the previous day, operating below normal at -13.03%. Conversely, the Truckee River showcases differing conditions along its course, with the segment near Mogul flowing at 864 cfs, a notable 117.55% of the normal flow, despite a 24-hour decrease of 18.49 cfs. This river is particularly significant due to its popular whitewater trails, and such high streamflow percentages may indicate good conditions for water-based recreation. However, enthusiasts should be cautious of the potential for rapid changes in flow.
Major rivers like the Colorado and Carson show varied conditions; the Colorado River below Davis Dam is at 5050 cfs, slightly lower than normal at -18.04%, while the Carson River near Fort Churchill exceeds the normal by 18.63%. The Carson River's streamflow increase of 2.72 cfs in the past day could hint at the beginning of a trend towards higher water levels, which are important for the ecosystems and cities along its path. Notably, the Las Vegas Wash below Flamingo Wash Confluence near Las Vegas has seen a dramatic increase by 1111.96 cfs, soaring to 308.5% above the normal flow, which could signal flooding and warrants close observation for any further escalations. This report reflects the dynamic and changeable nature of Nevada's waterways, providing critical insights for recreational users and resource managers alike.
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.
