LAS TABLAS CREEK
LAS TABLAS CREEK. Las Tablas Creek rises eight miles southwest of Catarina in Webb County (at 28°12' N, 99°36' W) and runs north for nineteen miles to its mouth on San Roque Creek, three miles southeast of Catarina in southeastern Dimmitt County (at 28°17' N, 99°36' W). Two miles from its source the creek is dammed to form Blocker Tank. Rolling hills in the area are surfaced by clay and sandy loam that supports scrub brush, mesquite, cacti, and grasses; in the creek's lower reaches the terrain becomes flat with locally shallow depressions, and the vegetation changes to water-tolerant hardwoods and grasses.
