CHACON CREEK (Medina County). Chacon Creek rises four miles northwest of Castroville in east central Medina County (at 29°22' N, 98°57' W) and runs south for thirty-three miles to its mouth on Francisco Perez Creek, just south of the Frio county line and two miles east of the Missouri Pacific tracks (at 29°05' N, 98°56' W). Together the two creeks form the headwaters of San Miguel Creek. Chacon Reservoir, once known as Chacon Lake, is on Chacon Creek four miles north of Natalia. The creek passes initially through low-rolling hills and prairies surfaced by expansive clays that support grasses, mesquite, and chaparral. In its middle reaches the creek traverses low terrain surfaced by clays that support pecans, hardwoods, and grasses. Towards its mouth the creek moves through flat terrain with local shallow depressions, surfaced by clays that support water-tolerant hardwoods, conifers, and grasses.
