SALMON CANNON
Washington used 1 pneumatic fish cannon to solve salmon passage past a 60m hydroelectric dam; the result transformed blocked rivers into thriving spawning grounds
Washington used 1 pneumatic fish cannon to solve salmon passage past a 60m hydroelectric dam, using a pneumatic tube system to move migrating fish over major barriers.
