The following is from the 2007 Federal Register on NMFS final detemination on the ESA listing of Puget Sound Steelhead. There is lots info if you want to spend a little time with one of the search engines.


"We concluded that the principal factor for decline for Puget Sound steelhead is the present or threatened destruction, modification, or curtailment of its habitat or range. Barriers to fish passage and adverse effects on water quality and quantity resulting from dams, the loss of wetland and riparian habitats, and agricultural and urban development activities have contributed and continue to contribute to the loss and degradation of steelhead habitats in Puget Sound. We observed that previous harvest management practices likely contributed to the historical decline of Puget Sound steelhead, but concluded that the elimination of the direct harvest of wild steelhead in the mid 1990s has largely addressed this threat."
