Smallmouth and largemouth bass are moving up in preparation for the spawn. In the Overton Arm, anglers are catching the fish with crankbaits and Rat-L-Traps in coves and near drop-offs. Murky water seems to be the key. Anglers also are using a variety of plastic worms and swimbaits in greens and sliver colors for black bass. Catfish are starting to bite on anchovies fished at night in the Las Vegas Bay area.
