Soft jerk baits like the Sluggo or Zoom Super Fluke will trigger strikes also. You need to experiment with the speed and action of these baits to find out what the fish want. Throw them around small rock piles and isolated bushes rather than large areas of willows. Try to find small shadows on the water created by trees on the bank or boulders. And finally work the edges of drop offs on the outside of flats with a baby bass Rattletrap to find small mouths.
Plastic worms take fish all year long and summer is no exception.
When the fish are deep and uncooperative a Carolina rig can produce good fish. Long points with submerged structure on it will hold fish. If one side has a deep drop off it will be an even better spot. Use just enough weight to feel the bottom and adjust your leader to suit the fishes' mood, a shorter leader for an aggressive bite and longer leader for reluctant fish. Another pattern that can work well in the summer is fishing grubs rigged on a darter head along the dams.
