It seems like the impact on the overall watershed is being overstated. From one of the CBC articles

The samples were taken on Aug. 5 at five different locations along the Quesnel River, to determine potential impacts on drinking water quality and aquatic life.

Jennifer McGuire, also with the ministry, said there was still no expectation that aquatic life would be impacted by cadmium levels, but zinc levels were showing in excess of the more stringent guidelines.

"The numbers are under the acute level, but slightly in excess of the chronic guideline level," she said.

The samples were tested for pH, conductivity, turbidity, total suspended solids, total dissolved solids, hardness, alkalinity, nutrients, general ions, total and dissolved metals, and E.coli.

This isnt a BP level event based on the testing, very serious but not on that scale.
