SAN DIEGO CREEK
SAN DIEGO CREEK. San Diego Creek rises six miles northeast of Seven Sisters in northern Duval County (at 28°02' N, 98°28' W) and runs southeast for forty-five miles before joining Chiltipin Creek to form San Fernando Creek a mile northeast of Alice in central Jim Wells County (at 27°47' N, 98°02' W). San Diego Creek is named after the Spanish land grant made to Julian and Ventura Flores. Upstream, the creek crosses flat terrain with local shallow depressions, surfaced by clay and sandy loams that support water-tolerant hardwoods, conifers, and grasses. Downstream, the terrain is flat to rolling with local escarpments and a surface of deep, fine sandy loam in which grow brush and grasses.
