Ecora worked in partnership with Halfway River First Nation (HRFN) to conduct the BC Hydro Site C Fish Stranding Monitoring Program (Mon-12) from 2016 to 2020. The Project was intended to determine the magnitude of baseline fish stranding along the Peace River, from the Diversion Headpond (upstream of Site C) to the Many Islands area in Alberta for future comparison with construction and operations phases.

The Project included a major field inventory component, including the mobilization of four crews using jet boats to access shoreline sampling locations. Field sampling included fish capture techniques, including electrofishing, dip and seine netting, and searching the interstitial spaces within the river substrates to find, collect, and identify stranded fish following ramping events. The Project also included field mapping and assessment of stranding risk by habitat, slope, and elevation characteristics.

The Project required complex coordination with BC Hydro Operations, Site C contractors, boat operators, and field crews to achieve optimal timing of field sampling during ramping events at the Peace Canyon Dam.
