Leiningers Run

Leiningers Run is a tributary of West Branch Mahantango Creek in Juniata County, Pennsylvania, in the United States. It is approximately 4.9 miles (7.9 km) long and flows through Greenwood Township and Susquehanna Township.[1] The watershed of the stream has an area of 6.96 square miles (18.0 km2). A reach of the stream is designated as an impaired waterbody due to miscellaneous habitat alteration from habitat modifications not including hydromodification. The stream's drainage basin is designated as a Coldwater Fishery and a Migratory Fishery.

Course

Leiningers Run begins in a valley in Greenwood Township. It flows south-southeast for a few tenths of a mile and then turns east for a short distance before turning southeast. After several tenths of a mile, the stream turns east-southeast, receiving two unnamed tributaries from the right and one from the left before entering Susquehanna Township. It continues flowing east-southeast for a few tenths of a mile before turning east-northeast for several tenths of a mile, receiving one unnamed tributary from the right and two from the left before turning east. After a few tenths of a mile, the stream receives another unnamed tributary from the left before turning east-northeast again. After several tenths of a mile, it receives one more unnamed tributary from the left before eventually turning southeast and reaching the end of its valley. A short distance further downstream, the stream reaches its confluence with West Branch Mahantango Creek at the border between Juniata County and Snyder County.[1]

Leiningers Run joins West Branch Mahantango Creek 3.26 miles (5.25 km) upstream of its mouth.[2]

Hydrology, geography and geology

The elevation near the mouth of Leiningers Run is 459 feet (140 m) above sea level.[3] The elevation near the stream's source is 801 feet (244 m) above sea level.[1]

A reach of Leiningers Run is designated as an impaired waterbody. The cause of impairment is miscellaneous habitat alterations and the probable source is habitat modification that is not hydromodification.[4] One person has been issued a permit to discharge stormwater into an unnamed tributary of the stream during construction operations.[5]

Watershed and biology

The watershed of Leiningers Run has an area of 6.96 square miles (18.0 km2).[2] The stream is entirely within the United States Geological Survey quadrangle of Richfield.[3] Its mouth is located within 1 mile (1.6 km) of Oriental.[2]

Leiningers Run is one of the major streams in Susquehanna Township. There is agricultural land along the floodplain of the stream; this is one of the major areas of agriculture in Susquehanna Township, along with the floodplains of Dobson Run and the Susquehanna River.[6]

History

Leiningers Run was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1179173.[3]

A steel stringer/multi-beam or girder bridge carrying T-524 over Leiningers Run was constructed in 1930 and repaired in 2005. This bridge is 24.9 feet (7.6 m) long. A two-span bridge of the same type, but carrying T-415 across the stream, was built in 1939 and is 26.8 feet (8.2 m) long.[7]

Biology

The drainage basin of Leiningers Run is designated as a Coldwater Fishery and a Migratory Fishery.[8] The stream's designated use is aquatic life.[4]

There is a block of forested land with an area between 250 and 1,000 acres (100 and 400 ha) near the headwaters of Leiningers Run.[6]
