JARVIS CREEK. Jarvis Creek rises just south of Wharton and west of State Highway 60 in east central Wharton County (at 29°15' N, 96°03' W) and runs south for seven miles to its mouth on the Colorado River, three miles southwest of Lane City (at 29°10' N, 96°03' W). The creek is intermittent in its upper reaches. It traverses low rolling to flat terrain surfaced by clay and sandy loam that supports mixed hardwoods, pines, and grasses. One of its smaller branches, which rises just north of Lane City, is referred to as Little Jarvis and the main stream as Big Jarvis by the local residents.
