Five diamond lakes serving up thousands of acres of sparkling recreational waters and countless miles of shoreline fun. Space, blessed space. Lots of elbow room to fish, ski, swim, float, sail, rent a houseboat, cruise your party barge, spread a picnic, kick back and catch some rays on some of the cleanest, clearest waters on the planet. The five Diamond Lakes are Lake Ouachita and Lake Hamilton at Hot Springs, Lake Catherine near Malvern, Lake Greeson between Glenwood and Murfreesboro, and DeGray Lake at Arkadelphia.
