Manistee Lake in Michigan has a long history of industrial use, dating back to 1841 when sawmills were first constructed on the lakefront. Over time, various factories, including a paper mill and salt plants, were built along the lake's shores, and their pollutants were discharged directly into the lake or into nearby unlined landfills. A study conducted in 2003 revealed that the lake is contaminated with waterborne pollutants and contaminated groundwater, threatening the health of the lake's ecosystem and the organisms that inhabit it. The study also highlighted the need to address the issue of brine entering the lake and the unknown path of the groundwater plume contaminated by the PCA Superfund Site.

Industrial use of Manistee Lake began in 1841, with sawmills and factories later built along the lake
Manistee Lake in Michigan has a history of industrial use that dates back to 1841, when the first sawmills were built on its shores. Over time, the area surrounding the lake developed into a thriving industrial hub, with the establishment of various factories and manufacturing plants.
The lake, situated in the southwestern part of Manistee County, is characterised as a drowned river mouth lake, formed by the changing water levels of Lake Michigan thousands of years ago. The industrial utilisation of Manistee Lake had a significant impact on the surrounding area, shaping its economic and environmental landscape.
The sawmills constructed in 1841 were just the beginning of Manistee Lake's industrial transformation. Soon, other factories and plants were established along its banks, including a paper mill and salt plants. The presence of these industries transformed Manistee Township into a bustling centre of economic activity.
One notable industrial complex was established by Peters and included several saw and shingle mills, salt wells, and what was reputed to be "the largest salt block in the world." This complex, along with other industrial endeavours, contributed to the area's thriving economy and attracted a diverse range of businesses.
However, the industrial activities also had detrimental effects on the lake's ecosystem. Pollution from the factories and plants, including the paper mill and salt plants, was pumped into the lake for many years. This led to a decline in the diversity of species within the lake and the contamination of the groundwater.
Despite the pollution, Manistee Lake and the surrounding area remain popular for tourism and fishing. The lake is known for its scenic beauty and is situated near several public beaches. Additionally, the Little River Band of Ottawa Indians and the Lake Michigan Federation have shown concern for the lake's welfare, jointly sponsoring a conference on Manistee Lake's water quality.

Pollution from the paper mill and salt plants has reduced the diversity of species in the lake
Manistee Lake in Michigan has been a site of industrial use since 1841, when the first sawmills were built on the lake. Over time, many other factories, including a paper mill and salt plants, were constructed along the lake. These industrial sites pumped pollution from their operations into the lake for many years.
A 2003 study by Rediske found that the lake is being polluted by both waterborne contaminants and contaminated groundwater. The study also showed that the lake bed near the paper mill and salt plants hosted a less diverse range of species, with mostly pollution-tolerant organisms present. This is in contrast to the healthy populations of water bugs and tiny organisms found in the sediment of the Manistee and Little Manistee rivers, which feed into Manistee Lake.
The pollution in Manistee Lake is attributed to the dumping of industrial byproducts directly into the lake or into unlined landfills near the lake. This has resulted in the contamination of the groundwater, with an estimated seven billion gallons of pollution dumped, according to Rediske. The pollution is also believed to be coming from brine from decayed wells and possibly pipes along the lake's bottom near the Martin Marietta and Hardy Salt plants.
The impact of this pollution on the lake's ecosystem is significant, with reduced species diversity and the contamination of fish food sources. This has affected the lake's potential as a site for fisheries, as clean-up efforts could potentially restore the lake's health and make it one of the best fisheries in the state.
Despite the pollution issues, Manistee Lake and the surrounding area offer a range of outdoor activities, including hiking, biking, swimming, fishing, and kayaking. The nearby Nordhouse Dunes Wilderness Area and Lake Michigan also provide opportunities for camping, boating, and birdwatching.

Contaminants are present in the groundwater, with around seven billion gallons of pollution dumped into the lake
Manistee Lake in Michigan has been a site of industrial use since 1841, when sawmills were first built on the lake. Over time, many other factories, including a paper mill and salt plants, were constructed along the lake. These factories pumped their waste and pollution directly into the lake or into unlined landfills nearby for many years.
The presence of contaminated groundwater is a critical concern, as it indicates that the pollution has permeated the underlying water sources that feed the lake. This contamination can have far-reaching consequences, impacting not only the lake's ecosystem but also potentially affecting the surrounding water sources and groundwater-dependent ecosystems. The groundwater plume contaminated by the PCA Superfund Site, an area where a "black liquor" contaminant was discharged into unlined lagoons, is of particular worry.
The extent and impact of the groundwater contamination are not fully understood, and it is essential to conduct further studies to address this data gap. The groundwater plume's path and eventual release point are unknown, and as Rediske stated, "that's not going to be good." The contamination in Manistee Lake underscores the need for better waste management practices and stricter regulations on industrial waste disposal to prevent further environmental degradation and protect the health of the lake and its surrounding ecosystems.
Despite the pollution, some sources indicate that the water in the Manistee River Trail is safe for consumption. The USDA, which manages the surrounding forest land, has not issued any warnings regarding chemical contamination in the water. However, it is still recommended to filter the water before drinking to reduce potential risks.

The lake is polluted by both waterborne contaminants and contaminated groundwater
Manistee Lake in Michigan is a drowned rivermouth lake, characterised by a deep, steep valley that was formed when Lake Michigan's water levels changed between 9,500 and 4,000 years ago. The lake's primary inlet and outlet are the Manistee River, which flows into Lake Michigan.
Industrial use of Manistee Lake began in 1841 with the construction of sawmills. Over time, other factories, including a paper mill and salt plants, were built along the lake. These industrial activities have had a significant impact on the lake's ecosystem, with pollution from the plants and Manistee's sanitary sewer lines being pumped into the lake for many years.
One of the significant sources of groundwater contamination is the PCA Superfund Site, where PCA discharged a "black liquor" contaminant into eight unlined lagoons between 1951 and 1976. It is estimated that approximately seven billion gallons of pollution were dumped, and the groundwater plume created by this contamination is flowing under Manistee Lake. Brine from decayed wells and pipes along the lake's bottom near industrial facilities is also contributing to the pollution.
The pollution in Manistee Lake is a pressing issue that requires attention. While it may not be on the list of lakes currently monitored by organisations like the Lake Michigan Federation, the cumulative impact of industrial activities over the years has left its mark on the lake. Addressing the contamination and preventing further pollution are crucial steps towards restoring the health of Manistee Lake and its surrounding ecosystem.

The biggest question for the community is where the groundwater plume contaminated by the PCA Superfund Site is going
Manistee Lake in Michigan has a history of industrial use, with sawmills, factories, a paper mill, and salt plants built along its shores. These industrial activities have contributed to the pollution of the lake, with factories dumping their waste directly into the lake or into unlined landfills nearby from 1900 to 1970.
The pollution in Manistee Lake is a pressing issue, and a study by Rediske revealed the presence of healthy populations of water bugs and tiny organisms in the sediment of the Manistee and Little Manistee rivers, which flow into Manistee Lake. However, concentrations of these organisms, which serve as food sources for fish, were found to diminish in the sediments lining most of the lake, especially near industrial sites.
The study also raised concerns about the groundwater plume contaminated by the PCA Superfund Site, an area on the southeast part of the lake where PCA discharged a "black liquor" contaminant into unlined lagoons from 1951 to 1976. Rediske estimates that around seven billion gallons of pollution were dumped, and the contaminated groundwater plume is now flowing under Manistee Lake.
The critical question that the community needs to address is the fate of this contaminated groundwater plume. Rediske emphasizes the urgency of this matter, stating, "That's a very critical data gap... That's got to come out somewhere, and where it comes out is not going to be good." The uncertainty surrounding the plume's path underscores the need for annual studies and proactive measures to prevent further contamination of Manistee Lake and its surrounding water sources.
While Manistee Lake itself faces pollution challenges, nearby water sources like the Manistee River and Lake Michigan offer opportunities for recreation and exploration. The Manistee River Trail, surrounded by USDA forest land, provides access to clear and flowing water sources suitable for filtering and drinking. Lake Michigan, a short distance from Manistee, boasts scenic overlooks, sandy beaches, and ample opportunities for hiking, biking, swimming, fishing, and kayaking.
