RADICHA CREEK. Radicha Creek rises at Lampasosa Dam, seven miles southwest of Ricardo in southwestern Kleberg County (at 27°22' N, 97°56' W), and runs east for seventeen miles to its mouth on Cayo del Grullo, an inlet from the Gulf of Mexico, five miles northwest of Loyola Beach (at 27°23' N, 97°44' W). The stream traverses flat to rolling terrain with some local escarpments and shallow depressions, surfaced by sandy and clay loams and loose sand that support brush, grasses, water-tolerant hardwoods, and conifers.
