LAKE GEORGETOWN. Lake Georgetown, formerly known as North Fork Lake, and Georgetown Dam are located 3½ miles northwest of Georgetown on the North Fork of the San Gabriel River in the Brazos River basin in west central Williamson County (at 30°42' N, 97°42' W). The project is owned by the United States government and operated by the United States Army Corps of Engineers, Fort Worth District. Construction was begun in 1972 and completed in 1978. Lake Georgetown, formed by a rockfill dam 6,947 feet long, is used for flood control and recreation and as a water supply for neighboring communities. The crest of the spillway is 834 feet above mean sea level, and the conservation storage capacity is 220,100 acre-feet with a surface of 5,070 acres. The drainage area above the dam is approximately 246 square miles.
