DRY FRIO RIVER. The Dry Frio River is an intermittent, spring-fed stream that rises just south of Farm Road 337, which connects Camp Wood and Leakey, in Real County (at 29°47' N, 99°51' W) and runs south-southeast for sixty miles to its mouth on the main Frio, just below U.S. Highway 90 and southwest of Knippa in Uvalde County (at 29°17' N, 99°39' W). The stream descends the Balcones Escarpment in a winding course over a bed of limestone, gravel, and calcareous soil. Its course runs roughly parallel to that of the main Frio, and in Uvalde County Farm Road 1051 closely follows the stream. The surroundings of its upper reaches are typical of the heavily dissected canyonlands of the Balcones Escarpment on the southern edge of the Edwards Plateau, forested with open stands of live oak, mesquite, and Ashe juniper. In the lower elevations of the Dry Frio's southernmost reaches, immediately above its junction with the main Frio, the terrain levels off and is surfaced by the gravelly and loamy soils that support mesquite and blackbrush, characteristic of the South Texas plains.
