Casselman River At Grantsville.
The Casselman River is a 56-mile long tributary of the Youghiogheny River located in western Maryland. The river was historically used for transportation and logging in the 1800s. Today, it is popular for fishing, kayaking, and other recreational activities. The river is fed by several tributaries and is home to several species of fish, including trout and smallmouth bass. The Deep Creek Dam on the river creates the Deep Creek Lake reservoir, which provides drinking water to the region and is a popular recreational area for boating and fishing. The Youghiogheny Reservoir, created by the Savage River Dam, also feeds into the Casselman River. The river is also used for agricultural purposes, with farms located along its banks. The Casselman River is an important natural resource for the region and its communities.

History of the River
The Casselman River is a 56.5-mile-long (90.9 km) tributary of the Youghiogheny River in western Maryland and Pennsylvania in the United States.The Casselman River rises in Garrett County atop the plateau of western Maryland as two branches, the south one east of Meadow Mountain, the north one farther west, between Meadow Mountain and Negro Mountain. The two branches flow northward combining just southwest of Grantsville, Maryland. The river then continues north into Pennsylvania, following a great arc across the Laurel Highlands of Somerset County, Pennsylvania to the community of Confluence, where Laurel Hill Creek joins a few meters above the Youghiogheny River.The river has been used for transportation across the Allegheny Mountains, between the cities of Baltimore and Washington, D.C. in the east and Pittsburgh in the west. Two railroads followed the Casselman River from Meyersdale, Pennsylvania to Confluence. First is the B&O Railroad, running between Baltimore and Pittsburgh, which was completed in 1827, and is currently owned by CSX. Second is the Western Maryland Railway, which ran from Cumberland, Maryland to Connellsville, Pennsylvania. Although the Western Maryland was abandoned in the 1980s, the right-of-way has been converted into the Great Allegheny Passage, a rail trail bicycle and hiking path.
