@August do you have gizzard shad? emerald shiners? I fish a cold area, natural lake with gizzard shad, and my bass relate to bait heavily this time year. I'm finding that the bait still migrates daily, nighttime seems to be spent in the cover of the weeds, then a move to more open water. My only consistent spots are the choke points between these two types of areas and they are most productive for the first few hours of daybreak and the last hour and a half of daylight. Mid day, I do more searching of the large 20-30' deep flats, hoping for birds or fish busting to clue me in. I'm not working with anything other than a flasher, so I rarely if ever mark fish, just bottom comp and depth.
On these maps, I'm marking in yellow where I find bass ambushing shad at daybreak and nightfall and the red areas are where I'm finding shad eaters the further from night it is. The darker it is, the more time I spend throwing shallow. Now this doesn't hold true all the time, but it's a starting point for the shad eaters mid july till ice. Now that we're post turnover, mid column to bottom bouncing is my best depth range, though I still have no confidence fishing deeper than 30' down in a 55' deep lake. One other nugget gleaned, is I do better fishing the direction that the shad are migrating, meaning I sit in deeper water in the am and cast toward the nighttime haunts. Flip it at the end of the day.
As the water gets into the 40's, I feel like some of the bass make a home at the "shallow" edges of the red or the deep portion of the yellow and don't travel as much. I agree with @TnRiver46 that a small underspin is a great choice. Heavy compact spinnerbaits, deep diving jerkbaits, deep cranks, A-rigs, and metal jigs do most of the damage for me.

ps - side note; bass are probably always corralling bait in some ways in depths I can't see, but this is the time of year when a school of bass can pin bait dirt shallow and just go on a frenzy, some of the best fishing I've ever experienced. I always watch for signs, hoping
