NEBRASKA FLOW REPORT
Last Updated: December 4, 2025
Nebraska's river systems are currently experiencing a mix of streamflow conditions, with certain areas indicating potential for flooding and others showing signs of flow droughts. The Missouri River, a major waterway for the state, shows decreased streamflows across several locations including Decatur (16,400 cfs, 15.4 feet gage height), Sioux City (14,600 cfs), and Omaha (19,300 cfs), with streamflow percentages well below normal, which could impact recreational and commercial activities. The Platte River, another significant river, is exhibiting variable conditions, with North Bend reporting a substantial increase in streamflow at 4,920 cfs (3.68 feet gage height), possibly indicating flooding concerns. On the other hand, areas like Duncan are experiencing considerably low levels at 243 cfs, suggestive of flow droughts. Notable is the Loup River near Genoa, currently recording streamflows at an impressive 2250 cfs, well above the normal percent, potentially affecting nearby communities and ecosystems.
Whitewater enthusiasts and river users should be cautious as the Niobrara River near Sparks shows a significant 24-hour increase in streamflow (1330 cfs, 2.91 feet gage height), which might appeal to thrill-seekers but also signals flooding risks. Similarly, the Little Blue River near Fairbury has seen a dramatic rise to 230 cfs, indicating more than a hundred percent increase from the norm, which could impact local water trails. Conversely, the Big Blue River at Barneston presents low streamflow levels (131 cfs), which may affect recreational use. These snapshots of streamflow data across Nebraska highlight the diversity of river conditions, critical for those planning river activities, and for communities monitoring water resources for agricultural and municipal use.
Nebraska has a continental climate with hot summers and cold winters, which leads to high evaporation rates and low precipitation. Major surface flows include the Platte River, Republican River, and Niobrara River, which are all tributaries of the Missouri River. Major reservoirs and dams include the Kingsley Dam and Lake McConaughy on the Platte River. The state's hydrology is heavily influenced by the Ogallala Aquifer, which is the primary source of irrigation water for agriculture. Snowpack in the Rocky Mountains also contributes to the state's water supply. Nebraska is prone to flooding, with significant events occurring in recent years, particularly along the Platte River. Sustainable water management practices are necessary to address the state's water challenges.
