Background:

Radley Run is a a nearly 4 square mile catchment area located in portions of Birmingham, Westtown, and Thornbury Townships. The headwaters are located just east of route 202 and the stream flows west from there. Topography in the watershed is flat to rolling with mixed land uses including single and multi-family housing, agriculture, and recreational uses. Historical land uses including logging, intensive agriculture, and mill dam construction and abandonment have impacted the majority of Radley Run, which is classified by the Pennsylvania Department of Environmental Protection as a warm water fishery.
