OLD RIVER (HARRIS COUNTY)
OLD RIVER (Harris County). Old River is the name given to the four-mile-long channel or old bed of the San Jacinto River north of Lynchburg and east of Channelview in southeastern Harris County. The surrounding terrain is flat to rolling and is surfaced by sandy loam that supports hardwoods and conifers. In the 1940s United States Army Ordnance officials purchased 5,000 acres for the San Jacinto Ordnance Depot on land bordering the Old River and the San Jacinto River; the land purchased included the former home of Lorenzo de Zavala.
