Casa Blanca Lake is on Chacon Creek, a tributary of the Rio Grande, just east of Laredo International Airport in southern Webb County (at 27° 32' N, 99° 27' W). It is owned and operated by Webb County for recreational purposes. The first dam, built in 1946, with top elevation at 455 above mean sea level, was damaged by the first floodwaters impounded by piping underneath the earth embankment. Construction of the second dam began in 1947 and was completed in 1951. The lake has a capacity of 20,000 acre-feet and a surface area of 1,656 acres at elevation 446.5 feet above mean sea level. Among its recreational uses, the lake supplies water to a golf course owned by the county. The drainage area above the dam is 117 square miles. The surrounding flat to rolling terrain is surfaced by clay and sandy loam that supports mesquite, cacti, and grasses.
