CHARCO MARRANO CREEK
CHARCO MARRANO CREEK. Charco Marrano Creek rises nine miles east of Cotulla in central La Salle County (at 28°24' N, 99°05' W) and runs south for twelve miles to its mouth on the Nueces River, sixteen miles southeast of Cotulla (at 28°14' N, 99°04' W). The name is Spanish for "filthy pond." In the creek's upper reaches the surrounding flat to rolling terrain has locally shallow depressions and is surfaced by dark clays that support grasses, mesquites, and cacti. In the creek's lowest reaches, clay and sandy loams support water-tolerant hardwoods and grasses.
