Try just north of the little island, the A-frame, and the point to the east of the fishing pier as you leave the ramp. Also try fishing the area on the North East side, there are some big boulders on that shore line heading south from the pier. I have caught fish in 7-12 feet of water. A few month back I got a 15" crappie and a few 14" one in the last area.
Shhh! It is not necessary to tell all we know.
The handicapped pier at the marina does have about 10 feet of water under it and some good crappie are being caught. Directly in front of the pier there is a drop off to deep water within easy casting distance.
The pier across the lake from the marina on the east side also has water although not as much. Bear south east from the boat ramp. That pier is reachable from the Live Oak parking area with about a 1/8 mile walk. It is a hot spot in the spring.
