Need some help guys.

I have decided to get back into tourament fishing again. My first tournament will be on Dewey Lake, at the Swimming Pool Ramp. I have never been there let alone fished it. The tournament is 4-18-09 so I still have alittle time to do some research before I drive a couple of hours to it to prefish it. If anyone knows anything about this lake like average bass size/weight, primary forage, type of lake ie. deep/shallow, rocky/muddy/sandy, steep bluffs and so on. Also some of your lure and technice choices for getting bites in mid April on this lake?

Thanks Guys
