RE:Wind Storm Question
The streams in the Puget Sound area seem to have weathered the storm just fine. They all get serious flooding in fall-winter-spring that flushes (and deposits) new debris continually through and out of their riverbeds. The erosion problems suffered by many of these streams provide for a continual parade of trees being washed down banks and into the rivers.
When too much gets deposited and salmon/steelhead are blocked from ascending, the local groups (Washington Trout, the TU chapters, and FFF clubs) organize volunteer efforts to clean them up.
