Even with the dams coming down we'll not be seeing any 100# Chinook in the future. The reason they have gotten smaller is the fishing on them on their feeding grounds. That harvest strongly selects against older (larger) fish.

With approximately 75% of the harvest of Elwha fish happening in Alaska and BC (more BC) on the fish's feeding grounds expect the Elwha to continue to get smaller. That is also the problem with many of the PS Chinook stocks. Unless we see movement away from fishing on immature fish (ocean fisheries) it may not be much longer until our Chinook are no larger than ocean coho.
