Fixing culverts, at least the way WA is going about it, is about "an ounce of image is worth a pound of performance". They don't help Chinook. much, because we don't put culverts on true Chinook water. Their removal will help steelhead, cutthroat, chum, and coho. All ya gotta do is add fish to the escapement. Which isn't done.

We need to think big. On the creeks I worked on, we got 1.3 coho smolt per linear metre of stream spawned and about 0.1 steelhead for the same metric. So, if you go in and fix 100m of creek you might add 10 steelhead smolts. In that stream, the creek's capacity was about 1200 so a nice expensive 100m project got (maybe) a 1% increase.
