MICHIGAN FLOW REPORT

Last Updated: December 4, 2025

Michigan's rivers and streams are currently experiencing a range of flow conditions, with several areas of concern for water enthusiasts due to abnormal streamflows that may impact recreational activities and local ecosystems. The Ontonagon River near Rockland is showing a significant streamflow of 1100 cubic feet per second (cfs), which is noteworthy given its relatively low elevation of 670 feet. The Iron River at County Hwy-424 in Caspian has seen a dramatic increase in the last 24 hours, with a current streamflow of 814 cfs, representing an enormous 1072.91% increase from its norm, indicating potential flooding conditions. This could affect whitewater trails in the area, as well as communities along the river's banks.

Conversely, a number of rivers are experiencing lower than normal streamflows, such as the Middle Branch Escanaba River at Humboldt, which, despite a 41.35 cfs increase in the last day, still sits at a strikingly high 248.73% above its normal flow, potentially indicating an incoming flow drought. The Grand River, a major watershed for central Michigan, has significantly reduced flows across various locations such as near Eaton Rapids with 235 cfs, Lansing with 364 cfs, and Ionia with 584 cfs, all well below their respective normal percentages, which could impact recreation and water supply in these areas. Recreational users should also note the typically popular Manistee River near Wellston flowing at 1580 cfs, which is low for this time but might still offer some opportunities for seasoned paddlers. Overall, river users and local communities should stay informed on current conditions, as these fluctuations can impact safety, accessibility, and the health of riverine habitats.
