EAU CLAIRE, Wis. (WEAU) -- The Wisconsin Department of Natural Resources is urging beachgoers to play it safe this summer.
The DNR says some lakes may have higher levels of contamination, harmful toxins and bacteria.
The DNR also recommends avoiding swimming after heavy rain, which can sweep contaminants into lakes and rivers.
If swimmers can't see their feet when they're knee-deep in the water, they should probably stay on land. Lake management planner with the DNR Buzz Sorge says beachgoers should be especially aware of blue-green algae blooms.
"Blue-green algae do have the capability to produce algae-toxins that can be harmful to humans, as well as animals; so keep your pets out as a rule of thumb, and keep yourself out. If the water looks bad use some common sense and just don't go in,” explained Sorge.
Sorge says swimmers should always wash themselves as well as any pets that came in contact with the water at the end of the outing.
