The historic removal of the Klamath River dams is now complete.

Klamath River · Post-dam removal

The Problem

Four hydroelectric dams on the Klamath River blocked salmon and steelhead migration for more than a century.

CalTrout’s Role

With the dams removed, CalTrout leads scientific monitoring to understand dam removal and its impact on native fish.

The Result

The Klamath dam removal is the first of the top barrier-removal priorities to be completed.

Project Timeline

From planning to river recovery.

Restoration moves through careful study, coalition building, field work, and long-term monitoring.

Phase 01

Assess the watershed.

Map barriers, flows, habitat conditions, and the partnerships needed to move work forward.

Phase 02

Build the restoration plan.

Align science, permits, funding, landowner relationships, and community priorities.

Phase 03

Restore and monitor.

Complete field work, measure outcomes, and adapt the next phase based on what the river shows us.

Each drop that flows from your tap has to originate from somewhere. In California, that water starts high in the snowpack, the springs, and the headwaters of the Sierra Nevada, Cascade Range, and North Coast mountains. CalTrout works to protect and restore these source water systems, essential to the health of every community downstream.
