Project Goal:

Monitor fish migration following dam removal and assess the efficacy of this monumental restoration effort to build our understanding of dam removal, including how fish repopulate newly opened habitat and how they respond to landscape level restoration.

Threats:

Major Dams

Project Description

In July 2024, CalTrout and our partners launched the Klamath River Monitoring Program to build our understand of dam removal including how fish repopulate newly opened habitat and how they recover from landscape level restoration. The project team consists of a diverse group of interests including tribes, government entities, and non-profits.

How many salmon and steelhead are moving into the newly accessible habitat? What time of year are they moving? Where are they going after entering the restored area? These are all questions that the project team will answer through this program.

We will use a combination of methods in concert to learn from the salmon and steelhead returning to the Klamath following dam removal. These methods include SONAR imaging, netting, radio telemetry, and spawner surveys. SONAR imagery will give us an eye into turbid waters to record movie like imagery of passing fish on a continuous basis. Netting will document fish species assemblages, age, length, and genetic information and allow us to attach tags to fish. Radio telemetry will help us track fish migration into the 400 miles of newly re-opened habitat. Spawner surveys will give us information about their nesting locations. Together, these methods will follow the fish to uncover how they are responding to dam removal and inform how to focus future restoration efforts.
