February 16, 2000 – The Fisheries Service designated critical habitat for central California coast steelhead and 18 other West Coast salmonid populations. It also published protective regulations for West Coast steelhead that prevent illegal "take" of central California coast steelhead.
July 10, 2000 – The Service published protective regulations for listed West Coast salmon and steelhead populations.

September 2, 2009 – The Center and a coalition of conservation and commercial fishing organizations sent a letter to the California legislature opposing a flawed Delta bill package and opposing the approval of an environmentally destructive “peripheral canal.” The dams that would result from the bill package, along with the canal, had the potential to devastate the Bay-Delta ecosystem and its native fisheries.
