Like the guys above said, ask the folks at the bait shops (not Wal-Mart) and also the locals on the lake may provide alot of info. At least find out what depth the fish are holding and watch sonar as much as you can. A fish finder with transducer on trollin motor is VERY handy. Fish s l o w l y too. I like 1/32to 1/8oz jigs...tubes, twister tails, hair and road runners commonly used by many. White, chartruse, yellow, red or combo of works most of the time.
Spend as much time on water as you can ...and good luck don't hurt none either.
Early to bed, early to rise,
Fish like hell, make up lies.
