The Sacramento River and its tributaries are historical spawning grounds for numerous species of fish, including four runs of Chinook salmon and steelhead (called anadromous fish since they travel to the ocean and return to spawn).  Numerous water diversions, some dating back to the mid-1800s, have impacted the ability of anadromous fish to reach suitable spawning grounds.  Shasta and Keswick Dams block upstream passage to spawning areas in the McCloud, Pit and upper Sacramento River drainage.  Whiskeytown Dam blocks fish passage into the cool, clear reaches of the Upper Clear Creek watershed.  All of these diversions have contributed to a sharp decline in the number of anadromous fish making their way home each year.  The Sacramento River Basin (below Shasta Dam) encompasses 21,250 square miles.  Just less than half of the historical river is available to anadromous fish at this time.

In the past three years, much of the work being done by the Western Shasta RCD is centered around degraded streams that have a high potential to support spawning salmon populations of Chinook salmon and steelhead, if restored to a healthy, functioning state.

Restoration work includes erosion control and vegetation management, fuels management, agreements on the timing of water flows from the dams, assisting local landowners and interested parties in forming watershed groups who then participate in the planning process, injecting spawning gravel in strategic locations, isolating deep gravel pits to eliminate fish stranding, returning a natural channel meander to eliminate braided conditions caused by mining, where water temperature becomes too warm for fish survival and/or water dries up during summer months.

Section 3406(b)(1) of the Central Valley Project Improvement Act directs the Secretary of the Interior to develop and implement a program that makes all reasonable efforts to ensure that, by 2002, natural production of anadromous fish in Central Valley rivers and streams will be sustainable, on a long-term basis, at levels not less than twice the average levels attained during 1967-1991.  The program is called the Anadromous Fish Restoration Program.  The six species identified for restoration under this program are Chinook salmon, steelhead, striped bass, American shad, white sturgeon, and green sturgeon.  For more information about this program, click here - www.delta.dfg.ca.gov/afrp.
