Once a site is isolated from flowing water (or the main part of a lake), a fish salvage is performed; fish are removed from the work area and released to the lake or downstream area.
Before your work starts, the in-water work area is isolated from upstream and downstream fish habitat using nets. Fish are removed from within the work area and released downstream of the nets.
While not ideal, sometimes work must occur in winter. Fish may still be in the area, and you may still be required to perform a fish salvage and relocate them before in-water work starts. Be aware of acceptable in-water work windows for your area.
Both Fisheries and Oceans Canada (DFO) and the Water Security Agency (WSA) may require fish salvage work before construction starts. Permits may require fish be removed from the work area before significant in-water work starts.
A Scientific Collection Permit from the provincial government is typically required to handle fish (other than for recreational fishing). A permit is required to perform the fish salvage outlined in many permits.
