New stream-restoration approach may pay dividends in Michigan
A relatively new technique for stabilizing eroding stream banks is showing great promise in Michigan, as a demonstration project on Highbank Creek in Barry County has not only repaired a damaged creek, but has provided excellent fish habitat as well.
The technique, called “toe wood,” has been around for about a decade but hasn’t been used much in Michigan until now. Department of Natural Resources fisheries biologist Chris Freiburger learned of the technique and thought it had applications for some of the issues facing Michigan streams.
The area Freiburger chose for the demonstration project involved a stream that had been dammed for a mill more than a century ago. The dam had been partially removed in the 1920s, but the abutments were left in place until the landowner knocked them down into the creek out of safety concerns. The debris formed a partial dam that not only impeded fish passage, but also contributed to erosion on the stream. A significant amount of sediment was swept downstream, silting in about an acre and a half of Thornapple Lake.
The Barry Conservation District applied for a U.S. Fish and Wildlife Service fish passage grant, as well as a DNR aquatic habitat grant to remove the dam and restore the stream. Read more
