Drainage

All of Fayette County is in the Monongahela River Watershed, which in turn is a part of the Ohio and Mississippi River watersheds emptying into the Gulf of Mexico at New Orleans. Two of the principal tributaries of the Monongahela River, the Youghiogheny and Cheat Rivers, flow through Fayette County. 

Drainage for Each Direction

Southwest

The Cheat River drains the southwestern part of the County as far east as Chestnut Ridge via Grassy Run, Rubles Run, and many small tributaries. In addition, via Big Sandy Creek, the Cheat River drains the south end of the Ohiopyle Valley. 

Significant tributaries include: 

  • Braddock Run
  • Fike Run
  • Laurel Run
  • Little Sandy Creek
  • Piney Run
  • Quebec Run
  • Scotts Run
  • Stony Fork

Eastern & Northern Parts

The Youghiogheny River, flowing northward from Maryland, drains the eastern and northern parts of the County by means of:

  • A Great Many Small Streams
  • Indian Creek
  • Jacobs Creek 
  • Meadow Run
  • Mounts Creek

West

The western edge of the County is drained by Georges Creek, Dunlap Creek, Redstone Creek, and several small streams, all of which flow directly into the Monongahela River.
