The Darby Creek Watershed encompasses 49,920 acres and drains directly into and provides the water that sustains John Heinz Wildlife Refuge, the largest remaining freshwater tidal marsh in Pennsylvania. The refuge is a treasured green space teeming with a rich diversity of fish, wildlife, and plants native to the Delaware Estuary. The refuge supports a diversity of habitats, including freshwater tidal marsh, open waters, mudflats, and woodlands that the hundreds of species call home.arian zones, and including the John Heinz National Wildlife Refuge.
Tinicum marshes provide vital migratory stopover habitat for many migratory birds and provide food plentiful enough to support nesting pairs of bald eagles. Since it is the water from Darby Creek that sustains these important marshes it is very important that the water that flows from and through our urban communities in the entire watershed delivers the cleanest water to sustain all of the important wildlife that are dependent on the marsh for their food and nesting habitat.
