Onion River (Sheboygan River)

The Onion River is a 36.8-mile-long (59.2 km)[1] tributary of the Sheboygan River in eastern Wisconsin in the United States. Via the Sheboygan, it is part of the watershed of Lake Michigan.

Course

The Onion River flows for its entire length in Sheboygan County. It is formed in the town of Lyndon by the confluence of Mill Creek and Ben Nutt Creek, and initially flows southeastwardly, passing the village of Waldo. Near Cedar Grove it turns north-northeastwardly for the remainder of its course. It joins the Sheboygan River at the city of Sheboygan Falls.

Fishing

During the past decade, a number of initiatives have occurred to reclaim and restore the Onion River in hopes of encouraging natural trout populations to increase. The Onion River is the only Class I trout stream in southern Wisconsin, and its natural trout population severely decreased from the levels found during the mid-20th century. In 2008, the Wisconsin Department of Natural Resources reclassified all of the Onion River from County N upstream as a Class I trout stream, meaning that it contains naturally reproducing wild trout.

A Wisconsin Department of Natural Resources study showed that from 1997 through 2006, the natural trout population of this stretch of the Onion River has increased ten-fold due to these continued efforts. It is expected that this population will continue to increase as further efforts continue on this stretch. In 2011, the Lakeshore Chapter of Trout Unlimited, the Wisconsin Department of Natural Resources and Michels Corp. installed lunker structures in six spots along the river, which are expected to minimize erosion and stabilize the habitat for the trout and other wildlife.
