BUCKNERS CREEK. Buckners Creek rises four miles southeast of Rosanky in southeastern Bastrop County (at 29°54' N, 97°14' W) and winds gradually southeast, then northeast, for a total of about thirty-three miles before reaching its mouth on the Colorado River, just south of La Grange in Fayette County (at 29°54' N, 96°53' W). It crosses loamy uplands in Bastrop and Fayette counties before entering clayey soil near its mouth. Post oak woods grow in the area. The stream is named for early settler Aylett C. Buckner, who arrived in the La Grange area in 1819.
