Water quality results released for the Hay and Slave Rivers
Results of water quality monitoring conducted by the Department of Environment and Natural Resources in July indicate this year’s prolonged high water levels have resulted in more suspended sediment than usual in the Hay and Slave Rivers.
As a result of the increased sediment, many metals associated with silt and clay particles were also found at higher than usual concentrations in both rivers for July. In the Slave River, some concentrations of dissolved metals were also elevated, but most were within the range of what has been measured historically in the rivers.
