Besides the outmigrating "wild" Skamania strain juvenile steelhead that have developed quite a population on their own, I worry about siltation issues. Will there be any? If there is, I'm not for it. We already have a problem with a slide below Duffie crk. The cleaner the gravel, the better. Look what happen to the Sauk several years back with sand and silt. Wild steelhead took a good hit and that was from a major flood event. You were hard pressed to find runs that weren't filled in with sand and silt. They are just now starting to show signs of coming back. While that is an extreme comparison, I just think our few wild salmonids deserve the cleanest water we can give them since we wreak havoc on so many other levels of their survival.
