Restoration of the upper Salmon River watershed: projected effects of diversion removal on salmonid abundance
The Salmon River, located within the Laich-kwil-tach First Nations’ traditional territory on Vancouver Island, supports a diverse community of anadromous and resident salmonids despite having cumulative effects from historical resource development (Burt 2010a). Currently, BC Hydro’s diversion dam and transfer canal on the Salmon River provides water for hydroelectric power production in Campbell River, but restricts the upstream and downstream movement of native salmonids (Anderson 2009, BC Hydro 2012). This report addresses removing the Salmon River diversion and providing coho salmon (Oncorhynchus kisutch) and steelhead trout (O. mykiss) unrestricted access into the upper Salmon River watershed. This restoration project will mitigate projected effects of climate change on freshwater life stages of the Salmon River salmonids by addressing increasing stream temperatures and seasonal low flows. Completing this restoration project is the first step in recovering the salmonid productivity of the upper Salmon River., salmonid productivity, Salmon River, coho salmon, steelhead trout, ecological restoration, dam removal
