Idaho Fish and Game produced the above video about an in-depth study of the section of Boise River that runs through Downtown Boise.
The summary from Fish and Game:
Fish and Game took an in-depth look at the namesake river of Idaho’s capital city and found some interesting things, and you can see them in the new video posted above.
The lower Boise River (from Lucky Peak Lake downstream) has abundant populations of rainbow and brown trout, both of which reproduce in the river. Fish and Game also augments them with hatchery trout.
Despite its popularity as an urban fishery and heavy fishing pressure, harvest is light. However, surveys showed there’s room for improvement. Fish and Game biologists found very few hatchery brown trout are surviving in the river, so there’s still work to be done to fully understand how the river functions as a trout stream.
