JORDON CREEK. Jordon Creek rises about a half mile north of Luther Hill Camp in north central Fayette County (at 30°00' N, 96°49' W) and runs south-southwest for about seven miles, passing through several flood-control impoundments before reaching its mouth on the Colorado River, at the foot of Chalk Bluff about two miles north of La Grange (at 29°57' N, 96°53' W). The stream traverses rolling terrain surfaced by a loose gravelly sand upper layer and a firm gravelly clay loam subsoil. These soils are poor for agricultural use. They are, however, used for unimproved pasture and are frequently mined for sand and gravel.
