The first priority is to catch one fish. Once you've located a promising spot, start with trial-and-error casting, using a lure that covers a lot of water, such as a diving or lipless crankbait or a spinnerbait. With a diving crankbait, make sure it's digging along the bottom. No matter what your choice of lure, be sure to bump the cover. The best crankbait colors are red, chartreuse-and-orange, and crawfish patterns. If you're fishing a spinnerbait, try chartreuse, chartreuse-and-white, and red-and-black, each with a large, single Colorado blade.
