My parents gated community has a community dock with lights. It has little to no structure at all around it. The water is 8ft deep under it but about 40 yards or so in front it's around 20 ft deep. We catch a pretty good amount of crappie from the dock at night during the winter and early spring but we have to throw as far as we can from the dock. I would like opinions on putting bamboo under the dock. How tall?

I am also going to put some bamboo in the 20 fow also that is about 8-10 ft tall.

I have talked to many locals and older gentlemen and they say the lake doesn't have near the structure as it did in the 80's and 90's.
