As demand for electric power increased, Couch began formalizing plans for hydroelectric development on the Ouachita River. The first of several such dams, Remmel Dam, was completed in December 1924. Carpenter Dam followed in 1933. The U.S. Army Corps of Engineers completed Blakely Mountain Dam in 1952, after Couch's death. Damming the Ouachita River transformed Arkansas's countryside and created three large lakes. Lake Catherine and Lake Hamilton in Garland County, popular lakes for public recreation, were named after Couch's only daughter, and close friend and company lawyer Hamilton Moses. Revenue generated by construction of Remmel Dam was in excess of $25,000 per year. Inexpensive energy produced by these new projects helped lure several major industrial plants to Arkansas. Pine Bluff received the state's first textile mill, the International Paper Co. opened a paper mill in Camden, and other companies followed.
