Deeper diving crankbaits. I would troll the dam area and the rip rap along the rail road bridges. Remember all lawton city lakes this one included you need a city permit to fish. At Ellsworth just stop in at Ralphs Resort and they will get you fixed up.
If you are in the market for a great used boat checkout the selecton of bass, catfish and all around fishing boats and boat trailers for all style of boats at www.facebook.com/smithboatsales
