::: Wow, great list! I'd like to see the following added in, for their historic significance: Willamette Falls Locks (not a dam, but important), Condit Dam, and Bull Run Hydroelectric Project. Also, I don't know the names of many of them  but do you have any dams on the Willamette River system? The one by Estacada on the Clackamas (is it Faraday Dam, maybe?) Detroit Dam? Lake Harriet? -
