90th Anniversary of Lake Catherine Lake Catherine was created between Hot Springs and Malvern when the Arkansas Power and Light Company (now Entergy Arkansas) completed Remmel Dam in 1924 to generate electricity. It was the state's first major hydroelectric facility. Though 11 miles long, the lake covers a mere 1,940 acres, nestled in narrow valleys of the Ouachita Mountains. The waters of Lake Catherine form one of the five renowned Diamond Lakes of southwest Arkansas. At Lake Catherine State Park, campsites and cabins stretch along the shore of the lake. This state park has been a family vacation destination ever since its construction in the 1930s by the Civilian Conservation Corps.
