I have caught several under feeding bass.
If you kind of make a short cast out away from the mob of feeding fish, let it fall below where you think the bass are, then work it like a wounded minnow under the school it works pretty good sometimes.
I pick it up one good jump, let it die, then a couple of short weak hops, then a bigger jump, that kind of thing.
My uncle caught a couple in 50 ish feet of water the other day. I think he said 5 keeper bass, 1 keeper walleye, 3 shorts, something like that.
At night they get shallow.
