It allows a large worm to swim through the rocks with a minimal amount of hangups. If you feel it wedged in the rocks just shake your rod tip and it will usually work itself free. Fishing from shore is restricted to the area from the boat ramp to the hot water outlet during waterfowl hunting season. A variety of techniques are used by shore fishermen.

Sonars are good search baits for active fish.
Slab spoons can be effective for schooling fish. Sassy Shads are a versatile bait, taking a variety of species. Mann's Little George are used in a variety of colors and sizes. Spinnerbaits can be slow-rolled through the rocks to catch bass. One trick I have found helpful is to wear chest waders and wade out just far enough to cast parallel to the shore and present baits parallel to the rock cover.
