Hopper fishing remains strong, especially through the mid and lower stretches. Mornings are best before the water warms—afternoons are tough with higher temps and moss. Foam hoppers like the Rio Juicy Hopper or Morrish Hopper are working well tight to banks. Tricos are still falling in the Fun Farm and Chester backwaters, offering some fun, technical dry fly fishing. A #20 organza spinner or #18 parachute Adams will cover you there. If you want to swing for bigger fish, work deeper holes with Elden's Shiner Minnow or Copper Zonkers.
