Dear Board,
If you cruise the forest roads in the Bald Eagle, Sproul, or Tiadaughton State Forests and come across a municipal water supply reservoir stop and look around as your courage permits. I've never seen anyone patrolling them, but it is possible. With patience you will see 16+ inch brookies swimming in them.
On rare occasions, when the planets align, and a flooding rain hits the tributaries that feed those reservoirs those fish are available to catch, especially in the Fall.
Somewhere I have a picture of two 17-inch brookies my brother and I caught out of the feeder stream of a Clinton County water supply reservoir. If I manage to find it, I'll post it.
Regards,
Tim Murphy
