MCCALL CREEK. McCall Creek rises in rugged terrain at Duncan Spring 3½ miles north of Blanco in south central Blanco County (at 30°09' N, 98°26' W). It flows east-northeast for nine miles to its mouth on Miller Creek, at the Miller Creek cemetery, 2½ miles east of the intersection of U.S. highways 281 and 290 (at 30°12' N, 98°20' W). It is intermittent in its upper reaches but is mostly free-flowing for the lower three miles of its course. It flows through loamy soil and rock outcroppings, past grasslands and stands of live oak, mesquite, and Ashe juniper.
