The watershed of the stream has an area of . The stream is impaired by sedimentation/siltation from agriculture and is a relatively small valley stream. Several bridges have been constructed across it. The stream is designated as a Warmwater Fishery and a Migratory Fishery.

Course

Dry Run begins on a low hill in Delaware Township. It flows north-northeast for a few tenths of a mile before reaching the bottom of the hill and gradually turning west-northwest. After more than a mile, the stream receives an unnamed tributary from the right and enters the census-designated place of Dewart. In Dewart, it flows west-northwest for a few tenths of a mile before turning west-southwest for several tenths of a mile and crossing a railroad. The stream then turns south for several tenths of a mile, exiting Dewart and crossing Pennsylvania Route 44/

A prestressed box beam or girders bridge carrying Pennsylvania Route 44 across the stream was built north of Watsontown in 1962 and is long. A bridge rehabilitation of the bridge carrying Pennsylvania Route 44 over Dry Run has been proposed for a cost of $945,000. In 2015, the Northumberland County Conservation District received a $200,000 Growing Greener grant to install animal fencing and implement streambank stabilization on Dry Run.
