Trinity County

Trinity County is in the East Texas Timberlands region. The center of the county lies at 31°07' north latitude and 95°05' west longitude. Groveton, the county seat of government, is near the center of the county and ninety air miles north of Houston. The county's name is from the Trinity River, which forms its southeastern boundary. Trinity County covers 692 square miles of rolling to hilly terrain that extends diagonally from the Trinity River northeast to the Neches River. The area is drained by these rivers and by a number of creeks that drain into them; near the southern tip of the county the Trinity has been dammed to form Livingston Reservoir, which provides water and recreation for the area. Altitudes in Trinity County range from 150 to 400 feet above sea level. Most parts of the area have reddish soils with loamy surfaces and clayey subsoils; in the western parts of the county, the soils are light colored with sandy surfaces and clayey subsoils. The county's climate is subtropical and humid, with warm summers and an annual average precipitation of forty-six inches.
