SAN YGNACIO CREEK. San Ygnacio Creek rises eleven miles northeast of Laredo in central Webb County (at 27°40' N, 99°20' W) and runs southwest for twelve miles to its mouth on Lake Casa Blanca, two miles northeast of Laredo (at 27°34' N, 99°25' W). Low rolling and flat terrain in the area has locally shallow depressions and is surfaced by clay and sandy loams that support grasses, mesquite, chaparral, and water-tolerant hardwoods.
