Bathing Beach Water Quality Monitoring


Macomb County has approximately 12 miles of Lake St. Clair shoreline, 3 beaches located on Lake St. Clair, and 2 additional inland lake beaches.

Lake St. Clair Metropark Beach-HCMA: Lake St. Clair

New Baltimore-Walter & Mary Burke Park: Lake St. Clair

St. Clair Shores Memorial Park Beach: Lake St. Clair

Stony Creek Baypoint Beach-HCMA: Stony Creek Lake

Stony Creek Eastwood Beach-HCMA: Stony Creek Lake


To assure residents and visitors of a safe and healthy recreational experience, the Macomb County Health Department conducts routine water quality testing from April 1st through September 30th each year. Water samples are tested for Escherichia coli (E. coli) bacteria.

The Macomb County Health Department will close a beach if the water sample bacteria level exceeds the Total Body Contact Standard established in the Michigan Public Health Code. The beach is re-opened once the bacteria level falls back down to acceptable levels.

To help locate and eliminate sources of E. coli bacteria and predict the occurrence of beach water quality problems, the Macomb County Health Department also monitors water quality at numerous sites along the Clinton River Watershed.
