SHEBOYGAN, Wis. – Michels Corporation, in conjunction with the Lakeshore Chapter of Trout Unlimited and the Wisconsin Department of Natural Resources, will commence its work on restoring the Onion River in Sheboygan County from May 31 to June 3. Michels will assist in preparing five to six sites along the Onion River for the installation of lunker structures, which help minimize erosion and stabilize the habitat. The 100-square-mile watershed has undergone sustained reclamation and restoration efforts since the late-1990s to help trout and other wildlife reinhabit the area. The Onion River is the only Class I trout stream in southern Wisconsin, and has seen its natural trout populations almost vanish since the mid-20th Century. The DNR reclassified all of the Onion River from County N upstream to a Class I trout stream in 2008. Per the DNR, the trout population there has increased tenfold from 1997 to 2006, due to these ongoing efforts.
