Hopefully you are bringing a boat or float tube. If you are willing to stay up late, I've had some AMAZING fishing in the dark. I'll usually come in and eat dinner at late dusk and then head back out once it is actually dark. Go to the other side of the lake and face the reeds so the headlamp you'll need isn't annoying everyone that is camping. Station yourself a comfortable casting distance from the reeds and throw 2 to 4 inch, unweighted, black leeches on a floating line. Cast to the weed line and strip them back. Half the time, you'll hear the fish explode on it before you ever feel the grab. I sure wish that place was closer to me...
