Not the day for it
River steady at a fishable height. Not much stacked in your favour today. Worth an hour if you are nearby, not worth the special trip.

About this water

Twenty Mile Creek is one of the eastern Pennsylvania Erie tributaries, smaller and more intimate than Elk. It is a classic stocked steelhead tributary — small shale water, fall and spring fish, and highly access-dependent fishing where public easements and etiquette matter as much as fly choice.
