Dry Run is a tributary of the Lehigh River in Northampton County, Pennsylvania, in the United States. It is approximately 2.6 miles (4.2 km) long and flows through Allen Township and Northampton.[1] The stream is designated as a Coldwater Fishery and a Migratory Fishery. It is often dry.

Course

Dry Run begins in a flat area west of Sauerkraut Hill in Allen Township. It flows south for several tenths of a mile before crossing Pennsylvania Route 329 and continuing to flow south. The stream eventually begins to gradually turn southwest and enters Northampton. Here, it flows west-southwest for a few tenths of a mile before turning southwest for several tenths of a mile. The stream then reaches its confluence with the Lehigh River.[1]

Dry Run joins the Lehigh River 22.14 miles (35.63 km) upstream of its mouth.[2]

Geography and geology

The elevation near the mouth of Dry Run is 282 feet (86 m) above sea level.[3] The elevation near the stream's source is 459 feet (140 m) above sea level.[1]

Watershed

The watershed of Dry Run has an area of 2.46 square miles (6.4 km2).[2] The stream is entirely within the United States Geological Survey quadrangle of Catasauqua.[3]

Polluted stormwater in Allen Township has the potential to impact Dry Run.[4] However, an NPDES permit was once issued for discharge of stormwater into the stream, associated with construction activities.[5] The stream frequently is dry.[6]

History

Dry Run was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1173531.[3]

In 1787, Christian Schwartz constructed a large stone house at the mouth of Dry Run.[7]

A lost Pratt through truss bridge was once built over Dry Run for the Lehigh Valley Transit Co.[8] Historically, a trolley bridge crossed the stream and a school was located near this bridge.[7] In 2014, the Delaware and Lehigh National Heritage Corridor received $217,000 from the Pennsylvania Department of Community and Economic Development to replace a pedestrian bridge over the stream.[9]

Biology

The drainage basin of Dry Run is designated as a Coldwater Fishery and a Migratory Fishery.[10]
