Fish Screening

Irrigation diversions are an important component of agriculture in the Blackfoot valley, but without careful design, they can seriously impact and in some cases totally eliminate trout spawning within a tributary.

BBCTU has upgraded 37 diversions on key tributaries with new gear that increases efficiency of water usage, eliminates fish entrapment, and reduces landowner labor in maintaining the diversion.

A variety of devices have been deployed depending on the specifics of the site.  Here’s some examples of our work:
