LOS OLMOS CREEK (Webb County). Los Olmos Creek, also known as Los Alamos Creek, rises thirteen miles northeast of Callaghan in northeastern Webb County (at 27°58' N, 99°12' W) and runs northeast for nineteen miles to its mouth on the Nueces River, twenty-two miles northeast of Encinal in southeastern La Salle County (at 28°07' N, 99°00' W). The surrounding flat terrain with locally shallow depressions is surfaced by expansive clays that support water-tolerant hardwoods, conifers, and grasses.
