Lake Tanglewood is on Lake Tanglewood, which was impounded by a dam on Palo Duro Creek in northeastern Randall County. The private, residential, year-round resort began in the early 1960s as part of a restricted land development corporation, Lake Tanglewood, Incorporated, which leased land from the Curry Ranch properties. The community incorporated in June 1971, perhaps spurred by talk of a trailer park to be developed there. Aldermen, a town marshal, and a constable were elected, and a volunteer fire department was started. In 1974 a nondenominational community church was completed. The town hall and clubhouse had previously been used for Sunday services. By 1984 Lake Tanglewood had a population of 485 and was the third largest town in Randall County. In 1990 the population was 637. The population grew to 825 in 2000.
