Jumped in on a trip with a few guys. I’ve never been there. Where gonna have a few boats, and staying close to where the bridge goes over it. I looked on the topo map and it’s a deep lake. There’s a smaller shallower area in the back side of it. Probably try that first. Any tips,hints or baits to try out would be greatly appreciated. 

I use to fish there a lot as a young kid but that was a long time ago.  I only fished the bottom/southern section but caught a ton of fish on rubber worms, spinners and spoons.   Hopefully the map below helps.

Thanks, that’s where I was thinking of starting
