“TARKINGTON BAYOU. Tarkington Bayou rises near Farm Road 2025 and Double Lake Recreation Area south of Coldspring in southwestern San Jacinto County (at 30Â°32' N, 95Â°09' W) and runs east of Cleveland and then south for thirty miles to its mouth on Luce Bayou in west central Liberty County (at 30Â°10' N, 94Â°59' W). The stream was probably named for Burton Tarkington, who patented the surrounding land in northwestern Liberty County. Near the mouth the creek crosses flat to rolling terrain with local escarpments surfaced by deep fine sandy loam that supports hardwood forests and conifers; it then runs into flat terrain with local shallow depressions surfaced by clay and sandy loam that supports water-tolerant hardwoods, conifers, and grasses.”

Tarkington Bayou begins in the Sam Houston National Forest in San Jacinto County, working its way south through Northeast and east Liberty County and joining other feeders, before traveling into Harris County and emptying into Galveston Bay. The highest point in Liberty County is “Davis Hill”, the roof of a salt dome in the northern part of the county.
