MCNUTT CREEK. McNutt Creek rises in the North and South Forks of McNutt Creek two miles east of Round Rock in southern Williamson County (at 30°35' N, 97°40' W) and runs southeast for seven miles to its mouth on Brushy Creek, four miles east of Round Rock (at 30°32' N, 97°36' W). It was probably named for Robert McNutt, the original grantee of the land through which it flows. The gently sloping terrain is surfaced by clayey soils used predominantly for agricultural purposes; its banks are heavily wooded in places with oak and mesquite trees.
