Pennsylvania Scenic Rivers are rivers that are designated "scenic" according to the criteria of the Pennsylvania Scenic Rivers Act (P.L. 1277, Act No. 283 as amended by Act 110, May 7, 1982). The scenic rivers are managed by a variety of State agencies and local conservancies. For the purposes of the act, "river" is defined as "...a flowing body of water or estuary or a section, portion, or tributary thereof, including rivers, streams, creeks, runs, kills, rills, and small lakes."
