Susquehanna Tributaries

These are streams that empty directly into the Susquehanna River but were not large enough (in terms of the mills on their path) to be given separate treatment.

Conewago Creek

The Conewago Creek is a 23-mile-long tributary of the Susquehanna River. Its source is in Mount Gretna Heights in Lebanon County, and it flows into the Susquehanna just north of the village of Falmouth in Conoy Township, Lancaster County. Its name is derived from the Lenape language meaning “at the rapids”. The Conewago forms the boundary between Lancaster and Dauphin counties.

There were several mills on the Conewago, but only one was on the Lancaster County side.

Conowingo Creek

The Conowingo Creek is a 20.2-mile-long tributary of the Susquehanna River. Its name is derived from a Lenape word meaning “at the rapids”. It originates in a pond along Route 272 in Providence Township just north of Buck. It flows mostly south through southern Lancaster County into Maryland. It enters the Susquehanna River just north of the Conowingo dam.

Conoy Creek

The Conoy Creek is an 11.2-mile-long tributary of the Susquehanna River. It originates near Elizabethtown and enters the Susquehanna at Bainbridge. The Conoy Creek is named after the Piscataway Conoy tribe that lived along its banks.

Fishing Creek

The Fishing Creek is a tributary of the Susquehanna River. It originates in a pond in Providence Township near Rawlinsville. It enters the Susquehanna River at Drumore about three miles north of Peach Bottom.

Shock’s Run

Shock’s Run begins above Stackstown Road west of Maytown and flows a little over two miles until it empties into the Susquehanna.

Snitz Creek

The Snitz Creek is a three-mile-long tributary of the Susquehanna River. It originates in West Donegal Township just west of Elizabethtown and flows into the Susquehanna near the head of the Northwest Lancaster County River Trail.

Witmer’s Run

Witmer’s Run is a one-and-a-half-mile tributary of the Susquehanna River that flows into the river just below Washington Boro.
