About the Mona Lake Watershed Council


Plagued for decades with excessive algae blooms, Mona Lake should be noticeably clearer after chemical treatment was applied following 20 years of study.


We regularly monitor Mona Lake’s water quality by performing controlled tests. We monitor for clarity and any contaminates. 


We continuously perform various studies with groups like Michigan Tech University to evaluate and provide recommendations.

Together We Can Protect
the Waters We Love

Our mission is to restore, protect, and maintain the Mona Lake Watershed as a viable natural resource for future generations and to inspire greater awareness, behavior, and knowledge through the use of science and education.

About the Watershed

The Mona Lake Watershed spans over 45,500 acres and covers 2,400 acres of lake and pond area. The majority of the Watershed lies within Muskegon County, with the exception of a small section of the northeast corner located in Newaygo County. It contains almost 23 miles of natural streams and creeks, with almost 40 miles of maintained drains. In the watershed, 23,600 acres is undeveloped consisting of forest, open fields, wetland, water, or dunes (roughly 52% of the watershed), 7,500 acres are used for agricultural development, and 14,500 acres are used for residential, commercial, and industrial use.

The future of our environment depends on what we do today to protect it.

Alum Treatment

Separate studies determined that the lake primarily in Norton Shores was plagued with high amounts of phosphorous that, when released from the mucky lake bottom, caused excessive toxic algae blooms that severely degraded water clarity.

The eastern portion of the lake was treated with alum – a chemical compound that binds with phosphorous and sinks it to the bottom, essentially capping it.


Watershed Improvement Plan

Celery Ponds to Receive Federal Funding

From: Don Trygstad, Chair of the Mona Lake Watershed Council

Mona Lake Watershed Council has been working for years with various partners to return the Celery Ponds to a beneficial wetland. We are excited to support the efforts of the Muskegon County Water Resources Commission with the NOAA grant. Please direct your questions to Commissioner Brenda Moore or Deputy Commissioner Dallas Goldberg.

Eighty-four years after the alteration of former wetlands along Black Creek and Mona Lake, the Muskegon County Water Resources Commissioner’s office is focusing on restoration with federal funds.

A true conservationist is a man who knows that the world is not given by his fathers, but borrowed from his children.
