I went down with 3 buddies early last year when they had nothing going on but the current was still strong enough to keep us moving at a steady rate so if its has any generators running I would use caution. One of my buddies paddled against the current but remained close to the bank, and tried to get close to the dam and he manged to hook a few big trout, he did get caught by a current that actually pulled him towards the dam, I wouldn't recommend getting that close lol.
