The Trinity River is the largest tributary to the Klamath River and it sustains important tribal, recreational, and commercial salmon fisheries. The Trinity River Division (TRD) was completed in 1964. With the TRD, up to 75-90% of the inflow into Trinity Dam was captured each year and exported to Southern California farms and municipalities. The impacts of flow regulation and other land uses combined to degrade the river and its salmon and steelhead habitat.

By 1970, the decline in fisheries became obvious. Studies were conducted and the Trinity River Restoration Program (TRRP) was developed to restore naturally-spawning salmon and steelhead populations to near pre-dam levels. In 2002, a Record of Decision (based on the TRRP) was signed by the Secretary of the Interior to begin the process of restoring the river. While the TRRP is considered the largest and most important experimental river and salmonid restoration program in California, its primary decision-making body has demonstrated a lack of shared and consistent vision.

Conservation Goal

  • Ensure that the original mission and vision of the Trinity River Record of Decision is fulfilled by the TRRP

What We Will Accomplish in 2013-14

  • Continue to support this vitally important Trinity River program as a model for large-scale river restoration and adaptive management.
  • Review and comment on the Science Advisory Board’s review documents and assess current implementation programs to ensure the TRRP is implemented in line with the vision expressed and shared
    by CalTrout.
