Oftentimes, when you are limited to where you can fish, like when bank fishing, you want to look for something that narrows the available water or that fish have to move through to get from one seasonal area to another.
One obvious pinch point that many anglers overlook are bridges. Bridges usually cut off one area of a lake from another and this often creates a migratory route for bass coming in to spawn from wintering areas and then leaving spawning areas to go out to summer haunts.
Current is often found in these areas from lakes rising and falling, or natural flow on a riverine system. And even wind can create a current in bridge gap that can create feeding opportunities at various times in the year.
