Coldwater River Watershed

Watershed Summary 

The Coldwater River Watershed is located in the southwestern portion of the lower Michigan peninsula. The Coldwater River Watershed is approved under the CMI administrative rules and was funded under section 319. To the east of the watershed is the City of Lansing; to its west is the City of Grand Rapids. The watershed covers approximately 120,737 acres. A majority of land in the watershed, 70.6%, is being used agriculturally. The decrease of sediment, bacteria, and thermal pollution has improved the aquatic life, wildlife, cold-water fishery, and macroinvertebrate community of the Coldwater River.
