CARRIZITOS CREEK. Carrizitos Creek rises seven miles southwest of Callaghan in central Webb County (at 27°46' N, 99°27' W) and runs northeast for twenty-two miles to its mouth on Venado Creek, thirteen miles northeast of Callaghan in north central Webb County (at 27°58' N, 99°12' W). The name is Spanish for "little cane," after the cane plants that once grew along its banks. The creek traverses low-rolling and flat terrain with locally shallow depressions, surfaced by clay and sandy loams. Local vegetation consists of grasses, mesquite, and chaparral in the creek's upper reaches, changing to water-tolerant hardwoods and grasses in its lower reaches.
