Something extraordinary—and deeply troubling—is happening at two major dams on the Columbia and Snake rivers.
Adult salmon reached the dams. Then inexplicably, they stopped. Within days, officials were confronting a migration emergency.
The fish ladders were open. The system had worked for decades. Yet this year, something was preventing large numbers of salmon from moving forward.
What changed? An operation ordered in the name of protecting fish.
This explosive investigation goes directly to the river to examine what happened after a federal court ordered unprecedented volumes of water to be released through dam spillways around the clock, and why the consequences now unfolding were not anticipated before the operation began.
It also takes a closer look at one of the most influential assumptions in Northwest salmon policy:
If some spill helps fish, more spill must help them even more.
The investigation uncovers a critical distinction largely mission from the public debate. And it shows what can happen when a simple policy slogan collides with the actual behavior of fish at the dams.
At the same time, enormous volumes of water are being sent past the turbines instead of generating the reliable, carbon-free electricity the Northwest urgently needs.
Those of us whose work is tied to the Columbia-Snake River System understand the stakes. But most people have never seen what increased spill actually looks like, heard the full scientific debate or understood the consequences for salmon and the power grid.
This investigation makes those consequences impossible to ignore.
Go to the river. Follow the evidence. Uncover the mystery of the 2026 salmon migration.
