For over a century, two dams sealed off Washington's Elwha River, wiping out nearly 90% of its salmon habitat and pushing the summer steelhead to the edge of extinction. Then, in the largest dam removal project in world history, the concrete came down — and the river did something scientists thought was close to impossible.
Salmon returned within months. Sediment rebuilt 70 acres of coastline. And a steelhead run declared functionally extinct came roaring back, traced to landlocked rainbow trout that had secretly carried the genetic instructions to migrate to the ocean for 100 years without ever using them.
