Kehly Run (also known as Kahly Run) is a tributary of Shenandoah Creek in Schuylkill County, Pennsylvania, in the United States. It is less than 2 miles (3.2 km) long and flows through West Mahanoy Township and possibly Shenandoah. The watershed of the stream has an area of 1.63 square miles (4.2 km2). The stream is located within the Western Middle Anthracite Field. A number of dams have been constructed across it. The stream is classified as a Coldwater Fishery and has macroinvertebrates, but no fish.
Kehly Run begins in Fetter Pond in West Mahanoy Township. It flows west for several hundred feet, passing through another pond and entering Number Six Reservoir. From the southern end of this reservoir, the stream turns south-southeast for several tenths of a mile, passing near Number Five Reservoir, crossing Pennsylvania Route 924, and entering a valley. In this valley, the creek flows in a generally southerly direction for several tenths of a mile, passing through Kehly Run Reservoir Number Three and Number Two Reservoir. Towards the lower reaches of this valley, in West Mahanoy Township, or possibly at or shortly after its end, in Shenandoah, the stream reaches its confluence with or becomes Shenandoah Creek.
Kehly Run joins Shenandoah Creek 5.01 miles (8.06 km) upstream of its mouth.
Kehly Run is designated as an impaired waterbody. The stream is impacted by abandoned mine drainage. However, it has been described as having "very good" water quality at site S11, in its upper reaches. In the late 1800s, the stream was described as having once been a stream of "good, soft, pure mountain water".
In March 2001, the discharge of Kehly Run was measured to be 1.56 cubic feet per second (0.044 m3/s), while in August 2001, it was 0.17 cubic feet per second (0.0048 m3/s). The dissolved oxygen concentration was 11.3 and 6.8 milligrams per liter (0.0113 and 0.0068 oz/cu ft) in March and August 2001, respectively. In March 2001, the pH was 4.7 and the net alkalinity concentration was −3 milligrams per liter (−0.0030 oz/cu ft), while in August 2001, the pH was 4.8 and the net alkalinity concentration was −2 milligrams per liter (−0.0020 oz/cu ft).
