Short for "Big One, RElatively Speaking", BORES is the only Class III rapid on Bull Creek. Access is available for park 'n' huck via a public parking lot off of Lakewood Dr. near 360.
BORES is created by a V-shaped limestone ledge. At high flows, water flows over both sides of the V and creates a large plume in the notch. Texas Whitewater describes an undercut at river right that "looks nastier than it is. Unless a tree is wedged in it, bodies and boats generally wash through." There is a sneak line at river left.
There is 1/8 mile of flat water below the rapid, so a failed roll or a swim here is probably not going to be consequential.
