Casselman River
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.
