Today, on the 50th anniversary of the Clean Water Act, is an opportune time to look at the law’s Clean Lakes Program. It was enacted as Section 314 of the Act and implemented in 1976 to address the degraded conditions of the nation’s inland lakes.

Congress has appropriated no funds for the Clean Lakes Program since 1995, even though 45% of the nation’s lakes continue to be in poor condition as a result of nutrient enrichment and other stressors, according to the most recent National Lakes Assessment.

The Clean Lakes Program provided funds to help assess the water quality of lakes in a state or tribal jurisdiction, conduct diagnostic feasibility studies to identify the causes of pollution in the lake, implement projects to mitigate the problems, and carry out post-restoration monitoring studies. The Clean Lakes Program awarded $145 million in grants through 1995.

Michigan is a lake-rich state with approximately 3,300 miles of Great Lakes shoreline and more than 11,000 inland lakes. Michigan’s history of lakes management dates back to the early 1900s, along with fisheries management and the desire to culture and stock fish in Michigan lakes and streams. However, prior to the passage of the Clean Water Act and the implementation of the Clean Lakes program, little water chemistry data had been collected on Michigan lakes, which hampered understanding and documentation of status and trends in lake water quality.

Michigan initiated a systematic effort in 1973 to monitor the quality of its inland lakes. However, by 1979 only 300 lakes had been sampled due to budget and staff constraints. Additional Clean Lakes Program funding became available to the states in 1980 as one-time grants for inventorying and classifying publicly owned freshwater lakes according to trophic or biological condition. Michigan was awarded a lake classification grant in 1980, which was the catalyst that launched Michigan’s inland lakes water quality monitoring and assessment programs. In addition to the lake classification grant support, Michigan was awarded 16 individual project grants: seven diagnostic-feasibility studies awards, eight restoration and protection implementation projects awards, and one post-restoration, monitoring studies award.

Another important section of the Clean Water Act is the Section 319 Nonpoint Source Program, established in the 1987 Amendments to the Act. Nonpoint source pollution is caused by rainfall or snowmelt moving over and through the ground, where it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters, and groundwater.

The 50th Anniversary of the Clean Water Act shows the work is far from done, especially for inland lakes.

Since 1990, the Environmental Protection Agency (EPA) has been providing financial support to states and tribes through Section 319 grants to implement their nonpoint source management programs. The EPA has encouraged states and tribes to use Section 319 funds to support the Clean Lakes work previously funded under the Section 314 Clean Lakes Program. The use of Section 319 funds to support lakes-related projects varies widely by state and tribe, but it has been reported in the range of 5-19%. Michigan does not track individual lake watershed projects supported with Section 319 grant funds.

There is support for expanding the implementation of the Clean Lakes Program by adding a “healthy lakes” component to protect high quality lakes and to prioritize lakes with significant cultural heritage value, as well as lakes in communities where there are environmental justice concerns.

The 50th Anniversary of the Clean Water Act shows the work is far from done, especially for inland lakes. The North American Lakes Management Society (NALMS) is calling for an “enhanced” Section 314 Clean Lakes Program with restored funding. NALMS is advocating for expanding the implementation of the Clean Lakes Program by adding a “healthy lakes” component to protect high quality lakes and to prioritize lakes with significant cultural heritage value, as well as lakes in communities where there are environmental justice concerns. An “enhanced” Section 314 Clean Lakes Program also will need to be fully integrated with other Clean Water Act tools, such as the Section 319 Nonpoint Source Program, Section 106 Water Pollution Control Grants, and the ongoing National Lakes Assessment.
