CourseShenandoah Creek begins in West Mahanoy Township, at or near the confluence of the tributary Kehly Run. Upon entering Shenandoah, the creek flows south and then in a southwesterly direction, crossing Pennsylvania Route 924. It then turns west for several tenths of a mile, entering West Mahanoy Township and crossing Pennsylvania Route 54. Here, the creek flows west-southwest in a valley alongside Pennsylvania Route 54 for a few miles, receiving the tributary Lost Creek and crossing Pennsylvania Route 54 once, before entering a pond and flowing into Butler Township. Here, it exits the pond and flows west for a few tenths of a mile before turning southwest. After a few tenths of a mile, it passes through a wetland, enters Girardville, and reaches its confluence with Mahanoy Creek.[1] Shenandoah Creek joins Mahanoy Creek {{convert|41.72|mi|km}} upstream of its mouth.[2] TributariesShenandoah Creek has two named tributaries: Kehly Run and Lost Creek.[1] Kehly Run joins Shenandoah Creek {{convert|5.01|mi|km}} upstream of its mouth and drains an area of {{convert|1.63|sqmi|km2}}. Lost Creek joins Shenandoah Creek {{convert|1.28|mi|km}} upstream of its mouth and drains an area of {{convert|1.32|sqmi|km2}}.[2] HydrologyShenandoah Creek is impaired by abandoned mine drainage throughout its length, and also by municipal point source pollution in one reach.[6] Shenandoah Creek's contribution to the waters of Mahanoy Creek causes the latter creek's flow to nearly double.[3] Geography and geologyThe elevation near the mouth of Shenandoah Creek is {{convert|958|ft|m}} above sea level.[4] WatershedThe watershed of Shenandoah Creek has an area of {{convert|12.1|sqmi|km2}}.[2] The mouth of the creek is in the United States Geological Survey quadrangle of Ashland. However, its source is in the quadrangle of Shenandoah.[4] Shenandoah Creek is one of the major tributaries of Mahanoy Creek. There are several lakes/ponds in the creek's watershed, and a wetland occurs in its lower reaches.[5] HistoryShenandoah Creek was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1187459.[4] A steel stringer/multi-beam or girder bridge carrying State Route 4031 over Shenandoah Creek was built in 1937 near Pennsylvania Route 54 and is {{convert|34.1|ft|m}} long.[6] BiologyThe drainage basin of Shenandoah Creek is designated as a Coldwater Fishery and a Migratory Fishery.[7] See also
