PIN OAK BRANCH
PIN OAK BRANCH. Pin Oak Branch rises in a tank one-half mile south of Northrup in southeastern Lee County (at 30°05' N, 96°58' W) and runs 6½ miles southeast, through parts of Lee and Fayette counties, to its mouth on Rabbs Creek (at 30°04' N, 96°53' W). Throughout its length it traverses rolling terrain surfaced by shallow and easily eroded sandy loam topsoil and a very firm clay subsoil, not well suited to agricultural uses other than grazing. Vegetation along the stream is generally sparse and includes a mixture of oak, cedar, and scattered pine.
