Buck, I don't know if you are a young buck or not, but you are underestimating the power of water! Like Fish Jesus said, anyone with a drift-boat or a sled knows what can happen when you make a mistake and are at the mercy of the current, or against a sweeper.
Most likely, if the tree is lodged in there, humans short of having a crane will not be getting it to move before the mighty Cowlitz will.
Wish I could have joined the flotilla myself, but being in my business on Father's Day and getting that day off....well as they say, when H*** freezes over.
