Bass can tolerate temperature change, but cannot survive without oxygen. Neither can the forage fish. Knowing this will help you to locate the comfort zone on a lake during the summer by finding where schools of shad are located. Words of caution here, don't think that schools of bass are always feeding on shad. In late fall and early winter, schools may be focusing their total attention on bream.
Bream tend to drop back into the bottom to the closest channel as each cold front passes.
I have caught schooling bass that were concentrated in five feet of stained water at Lake Somerville and in over 60 feet of water in Toledo Bend during the summer. While schooling bass are, at times, very willing to hit a wide variety of plugs, they can also be quite selective. There are few things more frustrating than seeing fish and not being able to catch them. Your range of choice for lures is going to be everything from topwaters to bottom-bumpers. So, let's take a look at the options and use of each one.
