Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.
The province is warning Manitobans to avoid the water at Ninette Beach, on northern Pelican Lake, after high levels of toxic algae were discovered last week. The concentrations of microcystin — an algal toxin that can be harmful to the liver or nervous system if large amounts of water are swallowed — at the southwestern Manitoba beach were "well above the recreational water quality objective," according to Manitoba's latest weekly beach conditions report, which was issued Friday.
New research by scientists at the University of Regina’s Institute of Environmental Change and Society shows that global warming is increasing levels of toxic algae detrimental to human health. The study was published online, in the journal Limnology and Oceanography Letters. “Our decade-long project establishes that global warming is increasing toxin levels in Prairie lakes,” says Dr. Peter Leavitt, a Canada Research Chair in Environmental Change and Society and a co-author of the study. “What is particularly worrying is that the chance of exceeding toxin levels that cause acute human health effects has increased to one in four in several lakes in southern Saskatchewan.”
