Check this report. http://www.heraldnet.com/article/20...TS02#Fish-the-North-Fork-Stilly-for-steelhead Might have some pertinent info with regards to your question. Interesting to note this particular statement also since it affects hatchery releases in the state especially in those cases where a hatchery needs to get their eggs from another hatchery. "In 2010, the state adopted sweeping hatchery steelhead reforms under pressure from the federal Endangered Species Act and certain conservation groups which, among other strictures, prohibit planting of steelhead from outside a river's own basin." (See the hatchery reform program at www.wdfw.wa.gov).
