My son & I are fishing a Tournament on Rocky Fork in Ohio March 13.  Any help is greatly appreciated.

Rocky Fork is one of the most productive lakes in SW Ohio and you should consider fishing other tourneys later in the year there as well; it has quantity and quality. Anyways, for that time of year, I would recommend targeting areas along the north shore with jerkbaits, and 5 inch shakey worms, particularly black w/ blue fleck or straight up blue fleck made by powerbait in 10 - 15 ft. of water. In some spots, they may be deeper. It's a very productive lake most of the time, but mid-march will be tough, so make your bites count because they may be few and far between. Also, dress warm because that lake can turn into a wind tunnel. Good luck and let me know how you do.

Also, I have had success putting senkos on jigheads or carolina rigs and hooking it up like a regular worm. Use black or blue fleck here as well or even green pumpkin with a chartreuse tail and watermelon/ red flake w/ a chartreuse tail.

Thank You Bucket.  That is indeed some great information.

I have good luck on plastic worms there.
