SAN LORENZO CREEK. San Lorenzo Creek rises twelve miles southwest of Carrizo Springs in southwestern Dimmit County (at 28°23' N, 99°59' W) and runs southwest for twenty-six miles to its mouth on the Rio Grande River, thirty-five miles southwest of Carrizo Springs in Webb County (at 28°02' N, 100°01' W). The creek is intermittent through all but the last quarter-mile of its course. The surrounding flat to rolling terrain with local escarpments is surfaced by deep, fine, sandy loam that supports brush and grasses; in the creek's lower reaches flat terrain with locally shallow depressions is surfaced by clay and sandy loams that support water-tolerant hardwoods and grasses. One of the earliest attempts at settlement in Dimmit County may have occurred along the banks of San Lorenzo Creek, when just before or during the Civil War people from Milwaukee are supposed to have settled on the creek near the boundary of Dimmit and Webb counties. The ruins of their ranch house were still said to be visible in 1930, just across the line into Webb County.
