Shingle Mill Run is designated as an Exceptional Value stream and has a population of native trout. The stream has high water quality and is slightly acidic. Boulder Colluvium and bedrock consisting of sandstone and shale can be found near the stream.
Shingle Mill Run begins in a valley in Davidson Township. It flows east for approximately a mile and its valley becomes progressively deeper. The stream then turns east-southeast for several tenths of a mile. It then receives its first and only named tributary, Bearwallow Run.
