Watershed Summary

The Hog Creek Watershed covers 68,928 acres in western Hillsdale and eastern Branch Counties, eventually outletting to the Coldwater River at Hodunk, then onto the St. Joseph River at Union City. The Hog Creek Watershed is approved under the CMI administrative rules and was funded under section 319. The designated uses are warm-water fishery, habitat for other indigenous aquatic life and wildlife, agriculture, and partial or total body contact recreation. Land use is 73% agricultural, 4% wetlands, 16% forested, 3% urban, 4% open fields, and other. This project significantly reduced sediment delivery from stream bank instability, agriculture and construction site runoff, nutrients and bacteria from livestock wastes and septic tank systems, and nutrient and pesticides from agricultural and other runoff.
