The Harsens Island/Krispin Drain Habitat Restoration project is now officially underway in St Clair County, Michigan.
The Krispin Drain is approximately 4 miles in length, and traverses the middle of Harsens Island. The project area includes a 200-foot wide easement along the centerline of the drain from the mouth of the drain at the St. Clair River and extends upstream approximately 2 miles to Krispin Road.
It also includes dredging and re-shaping the drain with 10:1 sloped benches and a defined thalweg, substrate enhancement, riparian planting, and invasive species control.
The objectives of the Harsens Island/Krispin Drain project are to remove invasive species and reestablish native vegetation, and to improve flow through the Harsens Island/Krispin Drain from the North Channel to the MDNR managed wetland facility.
According to the Clay Township Supervisor, Artie Bryson, the overall cost of the project will be around $3.8 million.
