MCCLUNG CREEK. McClung Creek rises just south of Ector in west central Fannin County at a point (33°33' N, 96°16' W). The stream is intermittent in its upper reaches. It runs southeast for six miles to its mouth on Bois d'Arc Creek, one mile south of Bonham (at 33°31' N, 96°11' W). The surrounding area is rolling prairie with locally steep slopes, surfaced by expansive clays, clay loams, and dark, commonly calcareous clays that support oak, juniper, mesquite trees, and various grasses.
