Welcome to BK Riverfish, LLC.

BK-Riverfish is an environmental consulting business that has developed a modern, affordable and highly effective fish ladder that passes migratory riverine fish of many species at dams and culverts.

See how our fish ladder works! Watch a continuous stream of fish resting in our ladder’s protective eddies then completing their natural migrations through our ladder to the top of the Stockdale Dam.

BK-Riverfish has developed the FIRST fish ladder in North America that’s designed specifically to pass multiple species of riverine fish at dams. We offer the ONLY fish ladder that’s affordable, modular and can pass a range of species and sizes – from 1.5-inches up to 32 inches.
