If you park at the launch, head left and keep left until you're away from the dam. Don't walk too close to the dam, as there's obviously a lot of moving water there. The good news is that most of Pachaug is shallow, so if you take a swim you most likely won't be in over your head! I would think you'd be fine, but you never know so spud your way out. Good luck - I saw a pic today of a 25 pounder someone pulled out of there on Jan. 15th. Nice and fat/healthy.
