Youghiogheny River

The Youghiogheny River ( /jɒkəˈɡeɪni/), or the Yough (/ˈjɒk/) for short, is a 134-mile-long (216 km) tributary of the Monongahela River in the U.S. states of West Virginia, Maryland, and Pennsylvania. It drains an area on the west side of the Allegheny Mountains northward into Pennsylvania, providing a small watershed in extreme western Maryland into the tributaries of the Mississippi River. Youghiogheny is an Algonquin word meaning "a stream flowing in a contrary direction".
