POST OAK CREEK (NAVARRO COUNTY)
POST OAK CREEK (Navarro County). Post Oak Creek, also known as Mesmeriser Creek, rises just west of Corsicana in central Navarro County (at 32°07' N, 96°30' W). The stream, which is intermittent in its upper reaches, originally ran southeast for twelve miles before entering Chambers (formerly Pecan) Creek near the community of Elm Flat (at 32°05' N, 96°20' W). After the construction of Richland Creek Reservoir in the 1970s, the lower watershed of the creek was inundated. The original name, Mesmeriser Creek, is said to have come from an early settler who believed that he could hypnotize buffalo. He built a pen and succeeded in corralling a large number of the animals, but the mesmerism failed and the animals trampled the fence and escaped. The stream was renamed around the time of World War II. It traverses flat to rolling terrain surfaced with clayey and sandy loams that support water-tolerant hardwoods and grasses.
