LAKE CISCO. Lake Cisco is three miles northwest of Cisco in northwestern Eastland County (at 32°26' N, 98°59' W). The lake, located on 445 acres where Sandy Creek was dammed in 1923, furnishes a water supply for Cisco. Golf and boating are also available. Lake Cisco drains an area of twenty-six square miles. It has an operating-level capacity of 8,800 acre-feet, and its flow has been supplemented since May 1956 by pumping from nearby Battle Creek. The moderately deep clay on its shores supports numerous short grasses.
