Smiley Run (Youghiogheny River tributary)

Smiley Run is a small stream located in Fayette County, Pennsylvania. It is a tributary of the Youghiogheny River, flowing into it from the west. The stream is primarily located within a rural, forested area and drains a relatively small watershed. Information regarding the stream's length, average flow rate, specific ecological characteristics, and recreational use is limited in publicly available resources. Its name likely derives from a local family or feature, as is common for minor waterways in the region. Further research of local historical records and geological surveys would be needed to provide a more comprehensive understanding of Smiley Run's history, geography, and ecological significance.
