Need help on Douglas

Hello all,

I will be bringing the family down to stay on Douglas for a seven nights in mid-June. I usually fish Kentucky and Barkley lake, never fished Douglas. Just looking for any help concerning the lake. The fish on Kentucky and Barkley have moved out to main lake ledges and humps. Had some good success over the holiday weekend with a Carolina Rig on drops (8-9 foot on top of the ledge - 15 to 20 foot on the bottom. (Mostly on watermelon lizards and creature baits.). Are the fish on the summer pattern on Douglas as well? Where can I get a detailed map of Douglas? I ordered a Hot Spots map but the contour level is not as detailed as I like. Thanks for any help.

Bobby
