The Hersey River is a high quality trout stream in lower Michigan, that historically contained the now extirpated arctic grayling. 

As common in the mid-1800’s, a dam was built on the Hersey River to power a mill.  Hersey Dam was near the river mouth (0.7 mile) and blocked nearly all fish migration between the Hersey and Muskegon Rivers. 

The Hersey River provides spawning, nursery and seasonal refuge habitat for Muskegon River fish and is one of the principal coldwater sources for the Muskegon River.  This dam had several uses throughout its history but was presently serving no purpose and in a dangerous state of decay. 

The town of Hersey, Michigan and the Muskegon River Watershed Assembly had spent over eight years identifying the problem and potential solutions, working through logistical details, and trying to secure funding for the project.  Additionally, the Michigan Department of Natural Resources (MDNR) completed a Watershed Assessment and Management Plan for this watershed that included specific plans for the removal of the Hersey Dam.  

The Green Bay Fishery Resources Office was contacted in 2005 about the possibility of funding assistance with this project.  A project proposal was submitted through the Fish Passage Program and funding was secured in early 2006.  The dam was removed in October of 2006, with the last few details wrapping up in early 2007. 

This removal opens up over seven miles of high quality habitat for native brook trout and other aquatic organisms.  The Hersey River now flows free in this area for the first time in over 148 years.  A total of $50,000 was provided through the Fish Passage Program, which represented 18 % of the total project cost ($274,000).  An assessment program on the Hersey River will be continued by the MDNR in order to quantify any change the dam removal has on the overall fish community.
