RIPPY BRANCH. Rippy Branch rises six miles southwest of Poolville in northwestern Parker County (at 32°56' N, 97°57' W) and runs southwest for seven miles to its mouth on Rock Creek just north of Lake Mineral Wells (at 32°51' N, 98°01' W). It was probably named for Edward Rippy, who lived nearby and was killed by Indians in 1870. Rippy Branch flows through undulating to gently rolling land made up of deep sandy and loamy soils that support grass and hardwood timber. For most of the county's history the Rippy Branch area has been used as rangeland and for mineral production.
