Connecticut

At regular boating levels if you can see the rock ledge mid-channel of river left branch, this is an easy scout from the ledge. This is the far left 'main' drop with well defined tongue and a rooster tail. There are generally 3 lines to be had in this section, depends on level and boater.
At higher levels, a vertical drop - perfect for beginner boofers - appears on the right side of the ledge in this channel.
The middle channel has a ledge you must navigate or at lower levels, portage (really just get out and throw your boat over).
The right channel is usually open and is consistently the easiest line. You can then approach Rock Dam from below and use the island and ledge to attain for a scout if you're inclined to check it out and give it a shot.
