FRANCISCO PEREZ CREEK
FRANCISCO PEREZ CREEK. Francisco Perez Creek, also known as San Francisco, San Francisco Perez, and Francisco Creek, rises two miles north of Highway 90 West and five miles northwest of Castroville in Medina County (at 29°23' N, 98°58' W) and runs south for twenty-five miles to its mouth on Chacon Creek, near the Frio county line (at 29°05' N, 98°56' W). Together Francisco Perez and Chacon creeks form San Miguel Creek. According to local tradition Francisco Perez Creek was named for Mexican trader Francisco Perez, who often camped on the creek before there was any settlement in the area. The creek rises in an area of flat to rolling prairie, surfaced by clays that support grasses, mesquite, and chaparral. Further along the stream's course the terrain changes to low-rolling hills and then to a flat area with local shallow depressions. Vegetation near the creek's mouth includes water-tolerant hardwoods, conifers, and grasses.
