Similar nuisance and hazardous blooms, spawned by excess agricultural fertilizer and animal waste, have plagued the lake for 20 years. But officials continue to insist that only voluntary measures by agriculture are needed to put the lake on the road to recovery. (Photo/U.S. EPA)
Although few people are likely to read it, a key report about the state of clean water in Michigan was published this year.
Prepared by the Michigan Department of Environment, Great Lakes, and Energy, the document has the ungainly title. Water Quality and Pollution Control in Michigan: Sections 303(d), 305(b) and 314 Integrated Report 2022. Nonetheless, it is important reading for anyone who cares about clean lakes and streams in the Great Lakes State.
Two key themes emerge from the report. First, most of Michigan’s open Great Lakes waters meet standards and support public uses such as swimming — and beach water quality is generally high.
Two key themes emerge from the report. First, with the exception of pollution of fish by PCBs, mercury, and other long-lasting contaminants, most of Michigan’s open Great Lakes waters meet standards and support public uses such as swimming. In addition, beach water quality is generally high:
- In 2020, 143 of 157 monitored public beaches on Michigan inland lakes reported no exceedances of the state’s E. coli standard. The remaining 14 beaches had 23 exceedances.
- Also in 2020, of 116 publicly accessible beaches on the Great Lakes and connecting waters, 92 reported no exceedances of the E. coli WQS for total body contact. The remaining 24 beaches reported a total of 57 exceedances.
Second, there are large pockets of degraded water quality that stubbornly resist pollution-control efforts.

“Repeated, persistent, and extensive cyanobacteria blooms,” resulting from an excess of phosphorus runoff from agricultural sources, undermine the water quality of the inner portion of Saginaw Bay. Therefore, EGLE has determined the inner bay is officially impaired.
Cyanobacteria blooms in western Lake Erie, also from agricultural processes, warrant an impaired listing. But EGLE continues to insist the best way to deal with this is to continue a collaborative process with Ontario and Ohio that has delivered little in water quality improvements, instead of writing its own plan.
Despite this generally good news, 50 years after the passage of the federal Clean Water Act, which called for making all of America’s waters swimmable and fishable by 1983 and the end to all pollution discharges by 1985, we are far from where we should be. The Act’s failure to deal effectively with agricultural pollution is a major reason.
