Bluegill - Good: Bluegill fishing has picked up a little bit more. Water temperature seems to be holding pretty steady despite the cooler nights.
Channel Catfish - Fair: Slow troll some cut bait down along the face of the dam and out around some of the brush piles in 6 to 8 foot of water.
Largemouth Bass - Good: As of yet the best time seems to be just before dark or just after. Spinnerbaits or jigs and trailer seem to be the place to start to catch them.
Water temperature in the upper 70's. Water still pretty green. Thermocline is at 6 to 8 feet. concentrate your efforts in this zone.
