Swimmers in Windsor-Essex will have a tough time finding suitable lake water in which to swim this long weekend.

Only one of 10 local beaches present a low health risk to swimmers this weekend. The rest have high levels of E. coli.

The Windsor Essex County Health Unit has closed five beaches and recommends swimming not take place at four others.

Only Hillman Beach in Leamington had bacteria levels that showed a low health risk.

Cedar Beach (Kingsville), Colchester Beach (Essex), Holiday Beach (Amherstburg), Lakeside Beach (Kingsville) and Seacliff Beach (Leamington) are closed.

There are possible health risks and swimming is not recommended at Cedar Island Beach (Kingsville), Northwest Beach (Point Pelee), Sandpoint Beach (Windsor) and West Belle River Beach (Lakeshore).

The health unit uses the following measurements to assess health risks of E.coli per 100 ml at the beaches:

  • 100 or less indicates a low health risk.
  • 101-1,000 indicates a possible health risk and swimming is not recommended.
  • More than 1,000 indicates a health hazard and the beach is closed.
