SAN AMBROSIA CREEK. San Ambrosia Creek rises six miles northeast of El Indio in south central Maverick County (at 28°33' N, 100°13' W) and flows southeast for thirty-six miles before emptying into the Rio Grande three miles south of the juncture of Maverick, Dimmit, and Webb counties in far northwest Webb County (at 28°09' N, 100°07' W). The vegetation in the upper reaches features water-tolerant hardwoods, conifers, and grasses; mesquite and grasses predominate downstream. The creek rises in flat terrain with shallow depressions and flows into rolling prairie. The soils are clayey and of variable permeability.
