  • Muskegon River Fisheries Management Summaries 02232017
    Department of Natural Resources, Fisheries Division Muskegon River Fisheries Management Summaries February 23, 2017 Richard P. O’Neal The Muskegon River begins in north-central Lower Michigan, flowing from Higgins Lake and Houghton Lakes, southwesterly to the City of Muskegon and discharging into central Lake Michigan. The river is 212 miles long and drops 575 feet in elevation between its headwater and mouth (O’Neal 1997). The watershed incorporates over 2,350 square miles of land and approximately 94 tributaries flow directly into the mainstem. The original fish community of the river system was composed of 97 species, and there have been a number of species that colonized or were introduced. The most recent fish community surveys were conducted on Higgins Lake (unpublished 2011), Houghton Lake (O’Neal 2011), the river and large impoundments (O’Neal 2002), and Muskegon Lake (unpublished 2008). The Muskegon River Watershed Assessment provides substantial background on the physical characteristics of the river (O’Neal 1997), along with Wiley et al. (2009). The hydrology of the river is intermediate between coldwater and warmwater Michigan streams. Water temperature data and fisheries surveys verify the coolwater nature of this river (O’Neal 2001; O’Neal 2011). The predominant species of fish found in the river are suckers, but there are many sport fish also present in the river as well as the lakes. The lower river (from Croton Dam to Muskegon Lake), Muskegon Lake, Houghton Lake, and Higgins Lake provide some of the best fishing in Michigan. These summaries are intended to highlight the existing fisheries in the river system, and provide brief summaries of recent studies conducted on important fish species along with needed research.
