OHIO FLOW REPORT

Last Updated: December 28, 2025

Ohio's rivers and streams are currently experiencing a significant downturn in streamflow across the state, raising concerns for river enthusiasts and water resource managers. A sweeping analysis of streamflow data indicates that the majority of rivers, including major watersheds such as the Scioto, Great Miami, and Maumee Rivers, are flowing below their normal rates. For instance, the Maumee River at Waterville reports a streamflow of 463 cubic feet per second (cfs), a substantial 93.89% below normal, and even the Ohio River above Sardis shows a lower-than-normal flow, despite a slight increase in the last 24 hours. These trends suggest that various activities, including recreational water sports and fishing, may be impacted, and there is a need for heightened awareness around water conservation.

Moreover, this trend of decreased streamflows extends to popular whitewater trails, which could affect the viability of these activities if levels continue to drop. Notably, the Vermilion River near Vermilion and the Black River at Elyria have experienced significant changes in streamflow in the last 24 hours, with increases of 94.24% and 65.77% respectively, which can indicate rapid fluctuations in water conditions. Cities like Columbus on the Scioto River are seeing lower streamflows, with the river at Columbus flowing at 332 cfs, 88.44% below what is considered normal. Such low streamflows can lead to flow droughts and impact water quality and ecosystem health. While most areas are experiencing reduced flows, the Great Miami River at Hamilton has a current streamflow of 1340 cfs, a 76.61% decrease, which is substantial but less severe than some others. River and water enthusiasts should remain informed of local conditions and advisories, especially as certain areas may face the risk of water shortages or ecological disturbances if these trends persist.
