TU launches new archive for California coastal steelhead data

Trout Unlimited works with a wide variety of partners in California to conserve, protect and restore trout and salmon populations and their habitats. For many years, one of our primary partners in our effort to recover native Coho salmon and steelhead in coastal watersheds was the Center for Ecosystem Management and Restoration (CEMAR).

CEMAR closed shop in 2016—and several of its staff then came to work for TU, becoming our Conservation Hydrology team led by Mia Van Docto.

Prior to its close, CEMAR was a leading provider of scientific data and analysis related to salmonid populations and the key variables affecting their coldwater habitats, in particular streamflow. As part of this function CEMAR hosted some of the most authoritative and accessible information compiled about steelhead in the San Francisco Bay Area, the Central, South-Central, and South Coastal regions, and the legendary Eel River watershed. Much of that content was written and compiled by our friend and colleague, Gordon Becker, and we dedicate this page to him.

These materials are now archived on Trout Unlimited’s website, on this page. Go here to access this data, which is housed in easily downloadable PDF files. As part of our commitment to advancing the science of steelhead biology and management, TU will continue to host this information going forward.
