In September 2025, Muskegon Lake was officially removed from the EPA’s Areas of Concern list. It was originally designated one of the most environmentally degraded sites in the Great Lakes 40 years ago. NOAA Fisheries’ Office of Habitat Conservation, the U.S. Environmental Protection Agency, and other partners worked for decades to restore the area.
We addressed environmental challenges such as fish and wildlife habitat loss, contaminated soils, and hardened shorelines to meet the criteria for delisting. This milestone marks a major achievement for the Muskegon community and for Great Lakes restoration efforts.
“Early in the restoration effort, there was significant skepticism that Muskegon Lake could be cleaned up, and NOAA’s involvement helped demonstrate that recovery was achievable through sustained, science-based collaboration,” said Kathy Evans, habitat focus area lead for the Muskegon Lake Watershed Partnership. “NOAA provided critical technical expertise, on-the-ground support, and nearly half of the funding needed to restore fish and wildlife habitat and meet the criteria for delisting.”
Partners raised approximately $80 million to support restoration in Muskegon Lake, including more than $36 million from NOAA Fisheries, primarily through the Great Lakes Restoration Initiative.
Since 2008, NOAA Fisheries has partnered with the Great Lakes Commission to carry out restoration projects that:
- Restored and reconnected 134 acres of wetland and offshore habitat
- Restored more than 7,000 feet of shoreline
- Removed 347,350 tons of debris
- Removed 190,000 tons of contaminated soil
- Enhanced habitat for species such as walleye, Chinook salmon, largemouth and smallmouth bass, and threatened lake sturgeon
- Improved public recreational access
An economic study found that restoration generated an additional $28 million annually in recreational value and an estimated 500,000 additional visits per year.
“As Muskegon Lake was cleaned up and restored, we saw tourism return and measurable economic benefits tied directly to habitat restoration and improved water quality,” said NOAA Great Lakes Restoration Program Manager Julie Simmons. “What truly sets Muskegon apart is the level of commitment from local partners and community members, who didn’t just plan projects but stayed engaged—managing volunteers, restoring habitat, and sustaining the work that made delisting possible.”
History of Pollution
In the late 1800s, Muskegon was home to many different industries, including lumber mills, chemical companies, foundries, a coal-fired power plant, and a paper mill. Over time, these industries filled in the shoreline of the lake and contaminated the water and sediment with compounds such as mercury and polycyclic aromatic hydrocarbons. This resulted in habitat loss and degradation, water quality concerns, and declines in fish and wildlife populations.
In 1987, Muskegon Lake was listed as a Great Lakes Area of Concern, one of 43 “toxic hot spots” in the United States and Canada. Designation as an Area of Concern is based on a list of “beneficial use impairments.” These factors indicate how a waterway’s poor conditions are affecting the environment, human health, and the local economy. Local, state, and federal partners work to restore an Area of Concern by addressing its impairments. Once all a waterway’s impairments have been addressed, its designation as an Area of Concern can be removed, a process known as “delisting.”
Comprehensive Restoration Efforts
NOAA works through the Great Lakes Restoration Initiative to implement habitat restoration throughout the Great Lakes region, including in Great Lakes Areas of Concern. Through the initiative, we have provided funding to the Great Lakes Commission to support several habitat restoration projects in the Muskegon Lake Area of Concern. These projects, overseen by the West Michigan Shoreline Regional Development Commission, include:
- Veterans Memorial Park: Partners restored more than 15 acres of habitat and more than 6,000 feet of shoreline at this community memorial park. The work also included removing more than 40,200 metric tons of sediment and replacing an aging water control structure to allow for fish passage.
- Lower Muskegon River: Partners removed three dikes from a former celery farm to reconnect nearly 58 acres of wetland habitat with the Muskegon River.
- Muskegon Lake Nature Preserve: Muskegon Environment, Research, and Education Society’s Muskegon Lake Nature Preserve restored nearly 8 acres of wetland habitat.
- Former Amoco Site: Work at the former Amoco oil distribution terminal restored 9.8 acres of habitat and 575 feet of shoreline, and removed 1,700 feet of concrete wall surrounding the property.
- Heritage Landing: Strong storm events during record high Lake Michigan water levels led to damage and erosion at this site in 2017. Restoration and repair work improved habitat for fish and wildlife and helped prevent further erosion in the future.
- Bear Creek: This project reconnected more than 36 acres of coastal wetlands, improving water flow and fish passage to Muskegon Lake. Work also included removing roughly 120,000 cubic yards of sediment that contained harmful levels of phosphorus.
- Mill Debris Removal: This project removed more than 300,600 metric tons of logging-era sawmill debris from four different sites in Muskegon Lake. Restored open water and lake bottom habitats are expected to benefit lake sturgeon and other aquatic life.
- Boys and Girls Club: This project restored approximately 480 feet of shoreline and one-quarter acre of emergent wetland. It also removed debris from a half acre of wetland. This work enhanced habitat for Great Lakes native species, including northern pike, largemouth and smallmouth bass, bluegill, and walleye.
NOAA and the Great Lakes Commission are also supporting ecological monitoring for many of these projects, which is being conducted through the Grand Valley State University Annis Water Resources Center.
In addition to our restoration work through the Great Lakes Restoration Initiative, NOAA selected Muskegon Lake as one of our ten Habitat Focus Areas. We also invested $10 million into habitat restoration in Muskegon Lake through the 2009 American Recovery and Reinvestment Act.
A 2011 study determined that, over 15 years, the Recovery Act funding we invested in Muskegon Lake restoration will result in a 6-to-1 return to the local economy. A 2020 follow-up study confirmed those projections, finding that habitat restoration in Muskegon Lake is improving area property values and boosting recreational opportunities for the surrounding community.
Combined, our many efforts in the Muskegon Lake region are helping to restore this important ecosystem and support Great Lakes fisheries and communities.
