APPLIED FISH PASSAGE RESEARCH

Flood control infrastructure in the Lower Fraser River currently blocks access to >80% of historical juvenile rearing and overwintering floodplain habitat for Chinook, Chum and Coho salmon populations. We have assembled robust collaborative research projects to better understand how flood infrastructure is impacting salmon in the Lower Mainland.

FISH PASSAGE AND FLOODGATES

We are actively researching fish passage through three different types of floodgates on the Coquitlam River in ƛ̓éxətəm Regional Park (Colony Farm Regional Park). The study compares a rare automated floodgate (one of only two in the Lower Mainland) with a typical top mounted floodgate and a side mounted gate using novel and innovative which lets us see each individual salmon's success in passing at the floodgates. The research is being done in a partnership with UBC Pacific Salmon Lab, kʷikʷəƛ̓əm (Kwikwetlem), and Metro Vancouver Parks.
