In the 279 page assessment, the authors outlined a number of concerns including, “Effects on fish and fish habitat resulting from the harmful alteration, disruption or destruction of habitat, particularly due to the gradual drying up of Kapisikama Lake, hydrological changes to the watercourses and changes in water quality,” the assessment said and added, “Effects on the wetlands due to their destruction or disturbance, caused by the development of mine infrastructure and the drawdown of the water table.”

In the far northwest of Manitoba, the Seal River flows 260 kilometres through the thick boreal forest into Hudson Bay. It's the only major river in northern Manitoba without any dams. No roads lead to the river, and there's only one human settlement in the river's watershed. That community, the Sayisi Dene, is leading an initiative along with neighbouring Dene, Cree and Inuit communities to protect the 50,000 square kilometres of the watershed. That's an area of untouched wilderness roughly the size of Nova Scotia, which would be protected from industrial development if the community's proposal is accepted.
