The creek was originally called the Kaarondinhah by the Iroquois who inhabited the Susquehanna Valley. European settlers named it "John Penn's Creek" after William Penn's younger brother. It was renamed Penns Creek (without the apostrophe) in 1802 by an Act of Assembly. The creek drains a watershed of approximately 163 square miles (420 km2) in Snyder, Union, and Centre counties.
A large spring within Penn's Cave, a commercial cave that offers guided tours by boat, forms one source for this limestone creek.
The upper reaches of Penns Creek offer some of the best trout flyfishing in the Northeast, with a Green Drake hatch occurring in late May that is one of the largest in the world. Additional Hendricksons, Sulphurs, and Tricos also attract anglers. As the water travels towards the Susquehanna, the temperatures gradually warm to levels best suited for panfish.
Ongoing pollution and soil erosion in the region continue to degrade the water quality and the environment locally as well as regionally. Farming, surface mining, wastewater treatment facilities and industrial spills are cited as contributing factors to loss of water quality. It also contributes to the pollution of the Chesapeake Bay. Controlling the wastewater discharges alone is expected to cost local taxpayers billions of dollars.
The Lower Penns Creek Watershed Association (LPCWA), the Susquehanna Greenway Partnership, and the Susquehanna River Basin Commission are organizations concerned with Penns Creek. The Snyder County Conservation District and the Union County Conservation District both have watershed specialists that participate in LPCWA.
