Hamilton is surrounded by homes with docks, Most docks (especially the ones with rodholders and light mounted on them) have brushpiles in front and under them.
Most of these will be around 18-25 feet deep. I know a lot of guys that drive over them and remember how high the pile comes to the surface then set their slip knot to that level, back off and fish a jig over them. There will be bass in most of those piles too. enjoy
