Description
The Rockcastle River is a 54.8-mile-long (88.2 km) river primarily in Rockcastle County, Kentucky, United States. It is a tributary of the Cumberland River and therefore, via the Ohio River, part of the Mississippi River watershed. The river has two forks, the Middle Fork, which forms in southern Jackson County, and the South Fork, which forms in Clay County. They meet at the Jackson County line and flow south, forming the southeast border of Rockcastle County. It makes up the border between Pulaski and Laurel counties before flowing into the Cumberland River. Due to the river carving into the Cumberland Plateau, many limestone and sandstone caves are formed. The river is used for recreational activities such as kayaking for sport through the rapid waters, and fishing for the many fish species. The river has an important native walleye population that has stabilized in recent years. The waters also contain over 65 fish species including rock bass, small mouth bass, with a variety of bluegill and other pan fish. Over 38 mussel species and 10 crayfish species are also found in the waters of the river. The small cave systems formed in the limestone provides a home for several bat species, amphibians, and reptiles. Black bears are known to swim the waters and navigate the rocky banks.
