I actually know a place further down ther river where I think it's sandy but not sure haven't been to that area in a while. at the very least its an area of pebbles. Another thing is this area is kind of on the shallow, I havent been there in a while but I think its like 2-4 feet I'll have to go check it out. Do carp like to hang out under bridges? because I've seen a few carp just outside of the bridge and I believe the bottom is mud or sand there not sure.
