The Saskatchewan government has lifted a public health advisory about high levels of bacteria in Last Mountain, Echo, Pasqua, Katepwa, Crooked and Round lakes.
Tests done earlier this month showed high levels of E. coli, a bacteria that can make people sick if they ingest it.
The elevated bacteria levels followed torrential rains that flooded sewer systems and farm fields.
However, the government says tests done on water samples taken Monday have confirmed that levels of E.coli at all public beaches tested "have dropped to a level considered safe for swimming and in-water recreational activities."
The province is still urging the public to use caution at flooded beaches because of debris and other physical hazards caused by the flood.
