According to the Handbook of Texas, the community had a population of 20 in 2000. The community was established in the 1870s near a bend on the Colorado River and named Bowser Bend. The community was based around the farm of Mr. Sim Witted and the local ford of Colorado was called Whitted Crossing. They had a Farmer Alliance store, a schoolhouse, a church, a post office, and even a cotton gin, but as buildings were frequently destroyed by flooding, starting in the late 1880s when the schoolhouse burned, new buildings were erected on higher ground about a mile and a half south of Bowser Bend, with the new elevation at 1312 ft. A new post office opened there in 1892 and operated until 1921, when the mail came out of the Mercury post office, some eight miles to the west.
