Background

The Mica Tailrace Fish Indexing Study is a multi-year program to estimate the effects of the addition of two new turbines (Mica 5 and 6) on the ichyofauna and thermal regime in the 2.5 km of the Columbia River downstream of Mica Dam. A single year of fish indexing data (2008) was also available from a previous program. As per the Terms of Reference (TOR) the relative abundance, condition and spatial distribution of the fish populations was assessed.

Lower Columbia River Sculpin and Dace Stranding Analysis 2013

Thorley, J.L. (2014) Lower Columbia River Sculpin and Dace Stranding Analysis 2013. A Poisson Consulting Analysis Report. URL: https://www.poissonconsulting.ca/f/1090742912.

Background

Discharge reductions associated with the operation of HLK and Brilliant Dams on the Lower Columbia River, British Columbia, can cause fish stranding.
