Any irregularity in the basin. If your basin is 30ft and there are some 31-32 foot areas that is where I like to look. Don’t over look depression on the shorelines. You can get some hot shallow water bites from them.
I’ve gotten them from 8′ to > 45′. I know this sounds basic but the lakes nearby are rather large, so I check with the locals where the bite is. A good word of mouthy with a marked up map can help.
