“to restore and maintain the Trinity River’s anadromous fishery resources… [by] …rehabilitating the river itself”
– U.S. Department of Interior, Record of Decision, 2000

WELCOME

TRRP is a multi-agency program with eight Partners forming the Trinity Management Council (TMC), plus numerous other collaborators.

The TRRP implements the 2000 Department of Interior (DOI) Record of Decision, which directs DOI to restore the fisheries of the Trinity River impacted by dam construction and related diversions of the Trinity River Division (TRD) of the Central Valley Project. Water diversions of the TRD compounded impacts from gold mining and historic logging.
The main office is located in Weaverville, CA (contact) although various Partner offices include staff working in the program.
