The Blackwater River is a 65-mile-long river located in West Virginia. It is known for its clear waters, scenic beauty, and recreational activities such as fishing, kayaking, and camping. The river was named for its dark color, which is caused by tannins from the surrounding forests. The river has a significant history, as it was used by Native Americans for transportation and fishing. It was also used during the logging era to transport logs downstream. The Blackwater River has several tributaries and is fed by several reservoirs, including the Jennings Randolph Lake and the Mount Storm Lake. These reservoirs provide hydroelectric power and water for agricultural and recreational use. The river is also home to a variety of fish species, including trout and bass, making it a popular spot for fishing enthusiasts.
