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.
