“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.

The Trinity River was designated a Wild and Scenic River in 1981 and is managed by the BLM, California Natural Resources Agency, Hoopa Valley Tribe, U.S. Forest Service and Yurok Tribe.

Restoration Actions:

  • Based on early water year forecasts in February, technical representatives of the Trinity River Restoration Program are developing flow release recommendations to meet various restoration objectives and management targets. Final recommendations are not made until after the California Department of Water Resources issues the Bulletin 120 Water Year forecast in early April.

General:

  • The proposed Winter Variable Flows presented by TRRP at a public meeting on November 30th, 2017 will not be implemented this winter.  Reclamation has not completed the environmental clearance and the Trinity Management Council (TMC) did not hold a vote on implementation for 2018.
     
    TMC will address this topic at their March 28/29 2018 meeting in Weaverville for consideration of implementation in the winter of 2019.  
     
    The Bureau of Reclamation is responsible for the implementation of Safety of Dams releases, which are outside the scope of the TRRP or TMC actions.
