It is approximately {{convert|3.4|mi|km}} long and flows through Chapman Township.[1] The watershed of the stream has an area of {{convert|3.24|sqmi|km2}} and the stream has no named tributaries. It is one of the major streams in Chapman Township. Its drainage basin is designated as a Warmwater Fishery and a Migaratory Fishery. CourseIndependence Run begins in a valley in Chapman Township. It flows northeast for a few hundred feet before turning east-northeast for over a mile. The stream then turns east-southeast for several tenths of a mile, receiving one unnamed tributary from the left and one from the right. In this reach, it begins flowing near the border of the census-designated place of Port Trevorton. The stream eventually turns south-southeast for more than a mile, receiving an unnamed tributary from the right and entering Port Trevorton, where it immediately receives another unnamed tributary from the right. It continues flowing in the same direction for a few tenths of a mile until it crosses US Route 11/US Route 15. A short distance further downstream, the stream reaches its confluence with the Susquehanna River.[1] Independence Run joins the Susquehanna River {{convert|109.82|mi|km}} upriver of its mouth.[2] Geography and geologyThe elevation near the mouth of Independence Run is {{convert|404|ft|m}} above sea level.[3] The elevation of the stream's source is {{convert|678|ft|m}} above sea level.[1] A road runs parallel to Independence Run for much of its length.[4] Watershed and biologyThe watershed of Independence Run has an area of {{convert|3.24|sqmi|km2}}.[2] The stream is entirely within the United States Geological Survey quadrangle of Dalmatia.[3] Its mouth is located within {{convert|1|mi|km}} of Chapman and is also near the community of Independence.[2][4] Independence Run is one of the major streams in Chapman Township, along with Chapman Creek and West Branch Mahantango Creek. Many of the streams in the township have a tendency to flow through open agricultural areas, allowing sediments and chemicals to reach the stream. However, planting trees along streambanks to create a riparian buffer would improve this, as well as connect forest habitats.[5] The drainage basin of Independence Run is designated as a Warmwater Fishery and a Migratory Fishery.[6] In 2016, the Pennsylvania Fish and Boat Commission passed regulations affecting Independence Run from its mouth to a point {{convert|0.5|mi|km}} upstream. This regulation forbade any attempt to target or catch bass between May 1 and June 17, with immediate catch and release being in effect for bass the rest of the year.[7] HistoryIndependence Run was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1177726.[3] See also
