Donegal Creek Restoration Project Written by Mark A. Metzler The Donegal Donegal Creek is located in bouts of thermal pollution and the northwest corner of Lancaster sedimentation. In its pristine state, County,D Pennsylvania. This limestone one can only conclude the east stream has a 17.2 square mile branch had been a cold water fishery, watershed and flows through some similar to its western twin, but now of Lancaster County’s most fertile would best be described as a warm farmland.

To many people, Donegal Creek means trout fishing! The main stem 7 8 includes a 2.4 mile “delayed harvest fly-fishing” stretch, while the rest of the main stem and branches are open to “bait fishing.” Both the Pennsylvania Fish and Boat Commission and the Donegal Fish and Conservation Association stock trout during the spring and fall months. In addition to the stocked trout, an angler may encounter wild stream-bred brown trout when fishing the main stem and wild rainbow and brown trout (progeny from egg plant- ings) when fishing the west branch.
