(WAHSH-uh-tah), Rises in the Ouachita Mountains in west Arkansas and flows east-southeast and south through the Ouachita Mountains and the cotton-producing region of south Arkansas and northeast Lousiana and into the Red River system. It is joined by the Tensas River at Jonesville, Louisana, to form the Black River. Hot Springs, Arkansas, and Monroe, Louisana, are the largest cities on the river; also important are Arkadelphia and Camden, Arkansa. The river is navigable for shallow-draft vessels below Arkadelphia. Three dams in the river near Hot Springs—Remmel (completed 1925), Carpenter (1931), and Blakeley Mountain (1955)—impound respectively Lake Catherine, Lake Hamilton, and Lake Ouachita (63 square miles - Arkansas' largest). There is a hydroelectric power plant at Blakeley Mountain Dam. Felsenthal Dam in south Arkansas impounds Lake Jack Lee. The lakes, part of a Federal flood-control project, are the center of a popular recreation area.
