Bear Run is in the Appalachian Mountains and part of the Pittsburgh metropolitan area. The Fallingwater house, designed by architect Frank Lloyd Wright, is located on this stream at the locality known as Mill Run.[7]

Bear Run is inside the Bear Run Nature Reserve, protected by the Western Pennsylvania Conservancy.[8] Bear Run is a designated Pennsylvania Scenic River.[9] The nearest incorporated town is Ohiopyle, once a resort town for affluent Pittsburghers reaching the Ferncliff peninsula via rail. Ohiopyle today is the focal point of tourism in the Laurel Highlands, drawing many of the same visitors as Fallingwater, located a few miles away on PA State Route 381.[10][11]

Course

Bear Run rises about 3 miles northeast of Kaufmann, Pennsylvania,[1] and then flows southwest and west to join the Youghiogheny River about 0.25 miles west of Kaufmann.[3]

Watershed

Bear Run drains 6.47 square miles (16.8 km2) of area, receives about 48.1 in/year of precipitation, has a wetness index of 357.26, and is about 89% forested.[5]

Natural history

Bear Run is the location of Bear Run Watershed BDA. The large forested area of Bear Run, an exceptional value stream, provides habitat for three plant species of special concern.[12]
