Harmful amounts of blue-green algae have been found in the waters of Killarney Lake, Manitoba Conservation and Water Stewardship said.

Testing at several Manitoba beaches this week revealed levels of Escherichia coli (E. coli) were within recreational water quality guidelines and thus safe for swimming.

But the number of blue-green algae cells measured in Killarney Lake ranks higher than what is considered safe under the provinces water quality guideline.

Levels of microcystin, the toxin sometimes found in blue-green algae, was found to be below harmful levels, but the province posted signs at Killarney Lake beach warning people not to swim or let pets near shorelines where algae blooms are present.
