Here's an a link to a research paper on Central Valley Steelhead by Dennis McEwan, DFG Biologist. http://www.sjrdotmdl.org/concept_mod.../300001435.pdf
He points out that there is a paucity of info on steelhead and problems with coordinating research and monitoring efforts. This is hindering effective management. He also points out that some water management actions intended to help chinook salmon is detrimental to steelhead. On a somewhat positive note, he notes that there is evidence of wild steelhead in some San Joaquin tribs despite the changes that occurred in those streams.
Another book, California's Salmon and Steelhead, http://publishing.cdlib.org/ucpresse...n;brand=eschol contains articles by noteworthy salmon and steelhead advocates and fishery management professionals. Both the McEwan paper and this book provide some very good info on what our what our fisheries were like from a historical perspective and how we got to where we are today.
It's a tragic story.
