Muskegon Lake Long-Term Monitoring Project

Muskegon State Park


Muskegon Lake is a highly disturbed ecosystem listed as an Area of Concern (AOC) in the Great Lakes region. Yet there is a surprising lack of recent information on Muskegon Lake. Detailed and long-term understanding of the lake ecology is essential for wise management of this vital coastal ecosystem that connects the landscape (Muskegon River watershed) to the Lake Michigan.

In 2003, AWRI initiated a long-term monitoring program in Muskegon Lake. An endowment fund at the Community Foundation for Muskegon County helps defray the costs of this project. As residents on the lake, we feel both a responsibility and an obligation to monitor and research the ecological health of this water body. This information can then be used to help determine the most appropriate sites for restoration.

The monitoring program is designed both to provide consistent, scientifically rigorous information and to accommodate the information needs of the community. For example, discussions with the Muskegon Lake Watershed Partnership (MLWP) and the Muskegon Sportfishing Association resulted in modifications to the monitoring program to ensure that the data complement the needs of both the community and the PAC's Remedial Action Plan (RAP) to the greatest extent practicable.




Main Goals:

  1. Observe short-term and long-term changes in the ecological health of Muskegon Lake.
  2. Understand the mechanisms behind the changes we see in the lake's ecology.
  3. Integrate Muskegon lake ecology to the watershed level, and to society at large.
  4. Use the information generated from this study to remove (de-list) Muskegon Lake as one of the Areas of Concern (AOC) in the Great Lakes.

Six sites are being sampled for water quality 3 times per year for a suite of physical, chemical, and biological parameters. Chemical/physical parameters include nutrients (nitrogen and phosphorus), dissolved oxygen, temperature, light transmittance, and Secchi depth. Biological sampling includes measurements of the algal, benthic invertebrate, and fish communities.



Special thanks to Dr. William Jackson and the Muskegon Sportfishing Association for their generous gifts to the endowment.
