Watershed Facts

Trout Run joins Pequea Creek, which flows into the Susquehanna River, and the Chesapeake Bay.


This beautiful and heavily wooded ravine is well-known to nature-lovers and biologists. Clear water tumbles along a fairly steep gradient forming riffles and pools, with a glade and boggy area near an old railroad tunnel at the north end. The 198 acre preserve supports a hemlock grove lush with ferns and foliage. A variety of spring blooming wildflowers is found along the paths that line Trout Run, including skunk cabbage, round-lobed hepatica, wood anemone, dwarf ginseng, and Canada mayflower, along with a wide assortment of ferns. Large numbers of yellow birch.
