CONCEPCION CREEK. Concepcion Creek rises nine miles west of Benavides in central Duval County (at 27°34' N, 98°38' W) and runs southeast for seventeen miles to its junction with Agua Poquita Creek to form Los Olmos Creek, eight miles south of Benavides (at 27°30' N, 98°27' W). Concepcion Creek was formerly known as Rosalia Creek, after the Spanish Santa Rosalia land grant made to Rafael Ramirez. The surrounding flat terrain with local shallow depressions is surfaced by clay and sandy loams that support water-tolerant hardwoods, conifers, and grasses.
