Featured Project:
Bridge River Chinook Salmon Broodstock Collection 

This project is a collaboration between the St’at’imc Nation, Xwísten, BC Hydro and Coldstream Nature-Based Solutions.  


The goals of this project are to:

  • Mitigate the loss of natural production driven by modified hydropower dam operations

  • Preserve the genetic and phenotypic diversity within the Bridge River Chinook Salmon population. 


We operate an Alaska-style fish fence from August through September, collecting biological data from Chinook salmon that swim into the fence trap box. 


Chinook that are assessed to be in good condition have eggs and milt collected which are transported to a local salmon conservation hatchery.  Once fertilized, the eggs are reared until the following spring at the hatchery and then transported back for release, thereby enhancing egg-to-fry survival of this highly threatened and culturally- significant Salmon population.
