Turtle Creek is a 21.1-mile-long (34.0 km) tributary of the Monongahela River in Allegheny and Westmoreland counties in the U.S. state of Pennsylvania. At its juncture with the Monongahela is Braddock, Pennsylvania, where the Battle of the Monongahela ("Braddock's Defeat") was fought in 1755. In the mid-19th century, the Pennsylvania Railroad laid tracks along the stream as part of its Main Line from Philadelphia to Pittsburgh.

History
Turtle Creek is the English translation of the Native American name, naming the area for its abundance of turtles. In 1742, John Fraser and his family established Braddock at the mouth of Turtle Creek as the first permanent English settlement west of the Allegheny Mountains. George Washington visited the area in 1753-1754. It was the site of Braddock's Defeat on July 9, 1755.
Wall is located at the site of a farm purchased by James Walls in 1829. The property, on the south bank of Turtle Creek, was passed to James' sons Henry and John Walls, who lived in a log cabin near the heart of present-day Wall. A station on the Pennsylvania Railroad opened in the early 1840s, which was named "Walls' Station" in honor of the Walls family. Eventually, the name of the station and the town that grew up around it was shortened to "Wall Station". Henry and John Walls sold their property to their cousin Frank Wall, an engineer on riverboats who developed the property around the station. Wall got its name after this Frank Wall, whose said property development led to him being the owner of the first two houses erected in the region.
Watershed
The Turtle Creek watershed is the region drained by Turtle Creek. Sixty-six percent of its area is in Westmoreland County, with the balance in Allegheny County. Turtle Creek's source is in Delmont, Westmoreland County and its mouth on the Monongahela River is in North Versailles Township, Allegheny County. The watershed's area is 147.41 square miles (381.79 km2). It drains forests, farmlands, abandoned mines, and urban and suburban communities. 33 municipalities span the watershed. The lower watershed drains a heavily industrial area between the cities of Pittsburgh and McKeesport.
