The water temperature on Lake Tawakoni is 65 degrees, and we are Trophy Blue Catfishing in 3 to 5 feet of water. Fresh-cut gizzard shad is the key to catching Trophy Blue Catfish in March. We are using 24 to 30-inch San T Rigs with 4 to 6/0 circle hooks. Blue Catfish are holding near trees and creek channels.
