OHIO FLOW REPORT

Last Updated: December 21, 2025

Ohio's rivers and streams are currently experiencing a diverse range of streamflow conditions, which are of particular interest to water enthusiasts and environmental monitors alike. Notable observations include the Sandusky River near Fremont, which shows an exceptionally high current streamflow of 2620 cubic feet per second (cfs), a significant deviation from the norm at 274.42% of the typical flow, possibly indicating flooding risks near the Fremont area. Conversely, the Auglaize River near Defiance is reporting a meager 158 cfs, drastically below the usual, standing at -87.3% of normal streamflow, signaling a potential flow drought in the region. Additionally, the Tymochtee Creek at Crawford reported an alarming 881.31% increase in streamflow over the past 24 hours, a figure that river users such as whitewater enthusiasts must heed for safety reasons.

Specifically noteworthy for popular whitewater trails, the Maumee River exhibits varied conditions along its course, with Antwerp measuring a streamflow of 727 cfs, a 17.26 cfs increase in the last day, and a gage height of 7.46 feet. However, the Maumee River near Defiance and at Waterville shows a significant deficit in streamflow, with readings of -83.08% and -89.87% of the expected norm, respectively. The Cuyahoga River, critical to the Cleveland area, shows a moderate streamflow at Old Portage with 574 cfs and Hiram Rapids at 370 cfs but is experiencing lower than normal levels at 34.01% and 85.26% of normal, respectively. For cities along the Scioto River, such as Columbus, Piketon, and Chillicothe, streamflows are below normal ranging from -21.24% to -47.33%, with the Scioto River at Columbus posting a flow of 648 cfs. These conditions collectively suggest the need for ongoing monitoring by local authorities for water resource management and flood control, as well as cautious engagement by water recreationists for their safety and enjoyment.
