Dimple Creek (Tohickon Creek tributary)

Dimple Creek's GNIS identification number is 1173286, its Pennsylvania Department of Conservation and Natural Resources identification number is 03174. It has a watershed of 7.33 square miles (19.0 km²), and meets it confluence at Tohickon Creek's 19.90 river mile. Dimple Creek flows through Lake Towhee.[2][3]

Dimple Creek rises at an elevation of 520 feet (160 m) in the northern part of Haycock Township from an unnamed pond west northwest of Little Haycock Mountain. Flowing south, it receives a tributary from the left bank, then flows into Lake Towhee a lake formed by a dam in the creek. From there it flows to the southwest to its confluence with the Tohickon at the Levi Sheard Mill at an elevation of 456 feet (139 m). The stream is 3.89 miles (6.26 km), which results in an average slope of 16.45 feet per mile (3.35 meters per kilometer).

• Appalachian Highlands Division
  • Piedmont Province
    • Gettysburg-Newark Lowland Section
      • Diabase

Dimple Creek lies in an intrusion of magma into the local Brunswick Formation in the Newark Lowland section or rock, part of the Piedmont Province of the Appalchian Highlands Division. About 200 million years ago, about the time of the Jurassic and the Triassic, the magma intruded an cooled to form diabase consisting of labradorite and augite, very highly resistant to erosion.[4]
