Muskegon Lake in Michigan has been removed from the US Environmental Protection Agency’s Areas of Concern list after about decades of restoration work.
asserted
Lake → remove → work
The lake was designated one of the most environmentally degraded sites in the Great Lakes about 40 years ago.
asserted
lake → designate → Lakes
In September 2025, it was officially removed from the list after restoration efforts addressed problems including habitat loss, contaminated soils, and hardened shorelines.
asserted
efforts → remove → loss
Since 2008, NOAA Fisheries has funded restoration projects around the lake through the Great Lakes Commission, with local oversight from the West Michigan Shoreline Regional Development Commission.
asserted
Fisheries → fund → Commission
The work has restored and reconnected 134 acres of wetland and offshore habitat and more than 7,000 feet of shoreline.
asserted
work → restore → shoreline
It also removed 347,350 tons of debris and 190,000 tons of contaminated soil, while improving habitat for fish and wildlife.

How much habitat and shoreline was restored around Muskegon Lake
The restoration work changed several parts of the Muskegon Lake area.

They also removed 347,350 tons of debris and 190,000 tons of contaminated soil.
asserted
They → remove → soil
At Veterans Memorial Park, partners restored more than 15 acres of habitat and more than 6,000 feet of shoreline.

Why was Muskegon Lake removed from the Areas of Concern list
Muskegon Lake was officially removed from the EPA’s Areas of Concern list in September 2025, marking the end of a process that began after its designation about 40 years earlier.
asserted
that → remove → designation
The lake was listed because environmental conditions were affecting the waterway, fish and wildlife, human health, and the local economy.
asserted
conditions → list → waterway
Partners worked for decades to address the problems required for delisting.
asserted
Partners → work → delisting
These included fish and wildlife habitat loss, contaminated soils, and hardened shorelines.
asserted
These → include → loss
According to NOAA Fisheries, partners raised approximately $80 million for restoration in Muskegon Lake.
uncertain
partners → accord → Lake
More than $36 million came from NOAA Fisheries, primarily through the Great Lakes Restoration Initiative.
asserted
million → come → Initiative
Industrial pollution damaged Muskegon Lake’s water and wildlife habitat
Muskegon Lake’s environmental problems developed as industries expanded around the lake in the late 1800s.
asserted
industries → damage → 1800s
Lumber mills, chemical companies, foundries, a coal-fired power plant, and a paper mill filled parts of the shoreline and contaminated the water and sediment.
asserted
mills → fire → water
The contamination included compounds such as mercury and polycyclic aromatic hydrocarbons.
asserted
contamination → include → mercury
These conditions contributed to habitat loss and degradation, water quality concerns, and declines in fish and wildlife populations.
asserted
conditions → contribute → populations
In 1987, Muskegon Lake was listed as a Great Lakes Area of Concern.
asserted
Lake → list → Concern
The designation was based on beneficial use impairments, which indicate how poor waterway conditions affect the environment, human health, and the local economy.
asserted
conditions → base → environment
Wetland restoration reconnected habitats and improved fish passage
Projects also focused on reconnecting wetlands and improving habitat for fish and wildlife.
asserted
Projects → reconnecte → fish
At Lower Muskegon River, three dikes were removed from a former celery farm, reconnecting nearly 58 acres of wetland habitat with the river.
asserted
dikes → remove → river
At Bear Creek, more than 36 acres of coastal wetlands were reconnected, improving water flow and fish passage to Muskegon Lake.
asserted
acres → reconnecte → Lake
The project removed roughly 120,000 cubic yards of sediment containing harmful levels of phosphorus.
asserted
project → remove → phosphorus
At Muskegon Lake Nature Preserve, nearly 8 acres of wetland habitat were restored.
asserted
acres → restore → habitat
Another project removed more than 300,600 metric tons of logging-era sawmill debris from four sites.
asserted
project → remove → sites
