Really, I'm not trolling.

There are many undammed rivers that have declining runs. Last time I looked, the Skykomish and Snohomish aren't dammed and yet we have declining runs. In any case, all I said was that dams aren't the only cause for declining fish runs.

I'll accept the US wildlife service's explanation without reservation as soon as someone can convince me that they are always right.

Finally, it is a complex problem. There isn't a simple answer.
