I looked at the aerial view of the lake and it even shows the shade to be MUDDY! However, I will offer these tips for you.

This time of year I would SLOW troll the deeper water that looks to be toward the south end by the dam. Look for the dropoffs coming into the levee area where they probably dredged the dirt to build the levee. Running multiple poles(spider rigging) can sure make the difference here. I would definitely try using a 1/16 oz. head and maybe a black/chart. GLOW body on cloudy or overcast days and maybe an orange/chart. glow body on brighter days. Your "chart.glow tails" will make the difference in this type of water.

I would work the creek channels that pour into the levee dug runs as well. If you can find the "points" where this creek channel and the levee dug channels are, you will hit the gold mine! I would fish these hard this time of year.

I've never been to the lake but I am curious as to whether it is muddy from top to bottom? Remember, some lake will muddy at top due to constant runoff but the bottom or deeper water will be somewhat clearer. If this is the case you might get away with lightening the color up somewhat. If its not the case, the darker colors should prevail. Also, don't be afraid to try live bait on those jig heads without the body, it is a very deadly tactic at times.

Doyle Hudson from Midsouth Tackle leaves very close by to the lake. If you visit him at their manufacturing site, I bet he can offer some more tips as well. He knows his stuff when it comes to catching crappie!

I hope this helps.
