the dam i'm refering to is just downstream of the launch at broadripple park...u wont be able to take a boat down there unless its a canoe...it's not so much of a dam as it is a spillway. all the fishing we do below the dam and south of there is either wading or bank fishing. there is a small canoe launch about a mile downstream from the dam itself back by the art museum. this section of river holds some very large fish even though it gets quite a lot of pressure at times. there probably wont be too many people out around this time of year though. me and a couple buddies spent most of our summer fishing a few mile stretch of river, mostly went early in the morning or at night to avoid the majority of people. we must have caught 200+ fish, all released :). if your after bass, i have caught several smallies and a couple of largies pushing 2 1/2lbs. Mostly we did our best with catfishing though, I caught one that was about 22lbs and a couple others in the 10-15lb range. but again, this will require bank or wading for the most part unless you have a canoe. good luck to you.
