I dont fish there much anymore but you might want to try the Mississippi Dept of Wildlife fishing forum. There appears to be more MS folks on that forum. www.msdwfp.com.
I fish mostly just south of Vicksburg, Palmyra Lake. Can be very good at times for Crappie and is a super Bluegill lake. You ought to give it a try sometime. The MS river has been too low for 3-4 months to get in it but back up now. Hard to get into when Ms River is under 10' on Vicksbueg gauge.
