Anglers across the Upper Cumberland have a new reason to grab their fishing gear this winter as the Tennessee Wildlife Resources Agency stocking rainbow trout throughout the region. TWRA Fisheries Biologist Connor Ballard said the agency releasing an estimated 75,000 rainbow trout statewide as part of its winter stocking program. He added that rainbow trout are ideal for winter stocking because they thrive in cold water. “Trout, especially rainbow trout, they are gonna be happiest in water below 65 degrees. Ballard said TWRA will also hold a spring trout stocking program.
