MICHIGAN FLOW REPORT

Last Updated: January 1, 2026

In Michigan, the recent streamflow data indicates varied conditions across the state's rivers and streams, with some experiencing significant changes that may impact river and water enthusiasts. Noteworthy is the Iron River at County Hwy-424 near Caspian, which has experienced a massive surge in streamflow with a change of 810.43 cubic feet per second (cfs) in the last 24 hours, pushing it to an unusually high 742 cfs, which is 336.14 percent above the normal flow. In contrast, the Middle Branch Escanaba River near Humboldt has seen a significant increase of 41.35 cfs, bringing it to 188 cfs, an astonishing 248.73 percent above the normal flow. These abnormally high streamflows could hint at potential flooding risks, particularly along the Iron River and the Middle Branch Escanaba River.

On the flip side, the Ontonagon River near Rockland and the Sturgeon River near Alston have observed a decrease in streamflow, dropping to 25.01 percent and 18.26 percent below normal, respectively. These reductions could indicate flow drought conditions, particularly concerning for areas relying on these water sources. Popular whitewater trails in the state might be affected, and cities along the impacted rivers, such as Rockland, Alston, and Caspian, should stay alert for fluctuating water levels. The Grand River, a prominent watershed in Michigan, flowing through Grand Rapids and Lansing, has recorded a 5780 cfs flow at Grand Rapids, 29.6 percent above normal, with a slight decrease in the last day. Water enthusiasts should take note of these conditions, as the varying streamflows may alter recreational opportunities and pose safety considerations on the waterways across Michigan.
