FALL CREEK (Hamilton County). Fall Creek rises two miles north of Fairy in northeastern Hamilton County (at 31°52' N, 98°01' W) and runs northeast for seven miles to its mouth on the North Bosque River, in Bosque County just past the Hamilton county line (at 31°57' N, 97°57' W). It traverses flat to rolling terrain with local escarpments, surfaced by deep, fine sandy loam that supports hardwoods, brush, and grasses.
