SANTA ISABEL CREEK

SANTA ISABEL CREEK. Santa Isabel Creek, also known as Arroyo Santa Isabel, rises twenty-two miles northwest of Callaghan in north central Webb County (at 28°04' N, 99°45' W) and runs southwest for thirty-three miles to its mouth on the Rio Grande, seven miles northwest of Laredo (at 27°39' N, 99°38' W). The area has rolling hills and flat terrain with locally shallow depressions surfaced by clay and sandy loams that support scrub brush, mesquite, cacti, grasses, and water-tolerant hardwoods. The stream was reportedly named by Canary Islanders who arrived at its banks on Saint Isabel's day.
