PROJECT SUMMARY

CLIENT: BC Hydro

LOCATION: Fort St. John, British Columbia

DURATION: 2016 – 2019

PROJECT FEES: $900,000

KEY FEATURES

·      3 seasons of sampling undertaken within 139-km section of the Peace River

·      Multiple teams of samplers, using electrofishers and interstitial methods, were deployed simultaneously

·      More than 800 fish captured in first year of study

·      Multiple species of fish processed and identified on-site

·      Determination of magnitude of fish stranding relative to baseline conditions

·      Analysis of various mitigation strategy effectiveness

    

The Site C Fish Stranding Monitoring Program was intended to determine the magnitude of baseline fish stranding along the Peace River, from the Diversion head pond (upstream of Site C) to the Many Islands area in Alberta, and to compare the baseline conditions to construction and operations phases of the Project.

Ten days of sampling were undertaken every year of the Study, each of which was coordinated with BC Hydro to ensure suitable flow reductions occurred at the Peace Canyon Dam. A total of 150 sampling events were completed annually using a combination of electrofishing and dip nets in isolated pools and interstitial transects along suitable dewatered areas. Of those, 72 events had isolated and/or stranded fish present at the time of sampling which resulted in a total of 813 fish captured.

The most commonly observed species were longnose sucker, slimy sculpin, and longnose dace. Ecora field staff worked Halfway River First Nation (HRFN) to complete the Project.
