Change the Current
Help Us Change the Current
Dams block the rivers fish need to reach. The old answer is a fish ladder: slow, hard on the fish, and thirsty for water that could be making clean power. Whooshh found a better way. Fish swim in on their own, an AI camera recognizes each one, and a soft, misted tube carries native fish over the barrier in seconds. More than 10 million fish have made that trip, on four continents. Change the Current brings the people who believe in this work closer to it.
It started with fruit
Vince Bryan was building tubes to pick apples when he saw helicopters carrying buckets of fish, and asked if the tubes could carry fish. It sounded a little crazy. So they tested it.

"The fish pass through without so much as a scratch. Also, you won't have to divert water, as you do in a ladder system. Out here, the economy is all about agriculture, and water is gold."
Mark Johnston, Yakama Nation Fisheries Biologist
What Whooshh is changing
Over the dam in seconds
The PassagePortal carries fish over barriers of almost any height through flexible, misted tubes. No giant concrete ladder, and no long, exhausting climb.
Every fish recognized
FishlRecognition photographs each fish and identifies its species, so native fish go upstream and invasive ones can be removed. The river gets the right fish back.
Water back to the turbines
Ladders need a steady flow of water just to work. Whooshh needs a mist. That frees water to make clean power, up to 10% more at an existing dam.
