FPIP staff currently work on the Shasta Dam Fish Passage Evaluation (SDFPE). The SDFPE is a collaborative effort to evaluate the feasibility of reintroducing Chinook salmon and steelhead to tributaries above Shasta Lake. It is part of the Bureau of Reclamation’s response to the 2009 NMFS' CVP/SWP Operations Biological Opinion (BiOp).

The Winnemem Wintu Tribe (WWT) was a party to the 2009 NMFS BiOp. The WWT's Salmon Restoration Plan is their proposal for returning McCloud River salmon to the McCloud River in a cultural, scientific and ecological context. For more information about the Winnemem Wintu, please see

The Calaveras River Fish Migration Barriers Assessment Report provides an overview of structures in the Calaveras River system which may be barriers to migrating steelhead and salmon.

FPIP staff worked in collaboration with other agencies and stakeholders to complete the Budiselich Flashboard Dam Fish Passage Improvement Project and the Caprini Low Flow Road Crossing project.
