Conservation note

Lower Columbia River steelhead (the Sandy's fish) are ESA-listed threatened. There is a legal fishery on hatchery fish — retain fin-clipped fish, release wild steelhead in the water. We read whether the river is in shape and whether the run is in; we never score wild fish as a harvest target. Chinook and coho present, hatchery/wild mix; targeting rules vary.
