MICHIGAN FLOW REPORT

Last Updated: December 28, 2025

Streamflow conditions across Michigan's rivers show a mix of below normal trends with occasional spikes that suggest the potential for flooding in specific areas. The Ontonagon River near Rockland, experiencing an 80.62 cfs increase over the last 24 hours, now flows at 1100 cfs, which is 25.01% below its normal rate, yet the considerable rise could raise concerns for nearby communities. Similarly, the Menominee River at White Rapids Dam near Banat, with a modest 2.5 cfs increase, flows at 2460 cfs, just above its usual rate, may indicate localized flooding risks. The Middle Branch Escanaba River at Humboldt, flowing at an unusually high 248.73% of its normal streamflow, stands out with 188 cfs, a significant rise of 41.35 cfs in the last day, could impact whitewater enthusiasts seeking challenging conditions.

In contrast, notable rivers like the Grand River near Eaton Rapids and the Red Cedar River at East Lansing flow at 46.02% and 37.85% below normal, respectively, potentially signaling flow droughts that could affect recreational activities. The Grand River at Grand Rapids, a significant watershed with a current flow of 2940 cfs, has also seen a decrease of 28.33% from its normal streamflow, which could impact water-based recreation and ecosystems. Whitewater trails along rivers like the Sturgeon River and the Manistee River are experiencing flows significantly below normal, at 33.9% and 18.37% respectively, which could affect their navigability and challenge for kayakers and rafters. Overall, Michigan's river conditions present a complex picture of both potential flooding and low-flow scenarios, requiring river users and local communities to stay informed and prepared.

       



Michigan is characterized by a temperate climate, and the state is home to several major surface flows, including the Great Lakes and their tributaries, the Grand River, St. Clair River, and Detroit River. The state has over 1,000 dams and reservoirs, with the largest being the 5,000-acre Houghton Lake. Michigan has a diverse hydrology, with wetland systems, streams, and inland lakes contributing to the water cycle. The state's snowpack is a significant contributor to hydrology, with winter snowfall providing a significant portion of the water supply for the Great Lakes and their tributaries. Additionally, the state is prone to flooding due to its topography and geographic location, and heavy rainfall events can result in flash flooding and riverine flooding.
