IOWA FLOW REPORT

Last Updated: December 18, 2025

Iowa's streamflow conditions reflect a dynamic range of water behaviors, with several rivers experiencing fluctuations that draw attention to seasonal trends and potential hydrological concerns. Notably, the Raccoon River near West Des Moines has shown an extraordinary streamflow increase to 1300 cubic feet per second (cfs), which is 279.79% above normal, suggesting a possible flooding risk in the area. The Des Moines River near Stratford also experienced a significant spike, with streamflow surging by 312.47 cfs, indicating high water levels that could impact surrounding communities and recreational activities. In contrast, flow drought conditions are evident in rivers such as the Des Moines River At Ottumwa, which is flowing at a rate of 1090 cfs, 81.94% below the expected norm, potentially affecting water supply and ecosystem health.

The Cedar River, an influential watershed in the state, exhibits varied conditions with Cedar Rapids reporting 1950 cfs, which is 48.45% below normal, potentially impacting the city's water-related activities. The Iowa River, vital for both ecological and recreational activities, also shows a reduction in flow. Near Lone Tree, it flows at 1140 cfs, 55.32% less than average. Enthusiasts of whitewater trails should be cautious as these flow irregularities could alter the difficulty and safety of rapids. The Mississippi River at Clinton, a significant waterway with a current flow of 24100 cfs, has decreased slightly by 0.41% in the last 24 hours, yet it remains 40.67% below normal flow, which could signal broader regional implications. Water enthusiasts and communities along these rivers should stay informed about current conditions and prepare for possible changes in water levels, keeping an eye on both potential flooding events and periods of low water that may alter river accessibility and health.
