America's Migratory Fish Are Disappearing: 6 Shocking Facts

Pacific Salmon Are Disappearing from Western US Rivers

Dams, warming rivers, and habitat loss have devastated Pacific salmon runs. Without major intervention, several species face extinction in their native US river systems within decades.

Over 80,000 US Dams Block Fish Migration Routes

The United States has more dams per capita than almost any country on Earth. Fish passage solutions and strategic dam removal are beginning to reopen historic migration routes.

River Temperatures Are Climbing — Salmon Can't Survive Above 68°F

Climate change is warming US rivers faster than salmon can adapt. The Columbia, Snake, and Sacramento rivers regularly exceed lethal temperatures during summer months.

Dam Removal Is Restoring Ecosystems — The Elwha Is Living Proof

After the Elwha and Glines Canyon dams were removed in Washington State, salmon returned within months. The ecosystem's recovery exceeded scientific expectations — proving restoration works.

Salmon Support Entire Ecosystems — and Millions of Jobs

Pacific salmon feed eagles, bears, orcas, and forests with their bodies after spawning. Their disappearance cascades through entire ecosystems — and decimates fishing communities from Alaska to California.

The Window to Save American Freshwater Fish Is Closing Fast

Dam removal, cooling shade plantings, bypass channels, and climate action are needed now. Migratory fish are the canary in the coal mine for freshwater ecosystem health. Read Full Report →

Why This Matters for America

Data from federal agencies shows this issue directly affects millions of Americans. Understanding the scope is the first step toward meaningful action and lasting solutions.

Communities on the Front Lines

Across the United States, communities are experiencing the real-world consequences. Local economies, public health, and ecosystems are all interconnected—solutions must address all three.

What Researchers Are Finding

Leading scientists from NOAA, NASA, EPA, and universities nationwide are documenting alarming trends. The evidence is clear: urgent action is needed to protect America's future.
