Three beaches in Windsor Essex are on the "Not Recommended for Swimming" list.
Two are on the Lake St. Clair shoreline and the third is on Lake Erie.
West Belle River Beach and Sandpoint Beach had the highest e Coli counts and Cedar island Beach also has an elevated count.
All other area beaches are considered safe for swimming, except Holiday Beach which is closed due to erosion issues from the high lake level.
Weekly test results are posted on the Windsor Essex County Health Unit website.
