Trinity River Restoration Program

The Trinity River Restoration Program (TRRP) was initiated in 1984 to restore and maintain the fish and wildlife stocks of the Trinity River Basin to levels that existed just prior to construction of the Trinity and Lewiston Dams in the mid-1960s. The current phase of the program was authorized by a Record of Decision signed by the Secretary of the Interior on December 19, 2000, and has a goal of restoring naturally-spawning salmon and steelhead populations to pre-dam levels.

The TRRP is implementing a strong science program, significant physical/mechanical channel restoration actions in the mainstem, watershed restoration in the tributaries, and significantly increased flow releases to the river that mimic the basin's snowmelt driven hydrography. The Program is guided by the Trinity Management Council (TMC) and Trinity Adaptive Management Working Group (TAMWG). A TRRP field office was established in September 2002 to implement restoration activities and provide support to the TMC.
