The river was named after the sulfur-bearing springs found in the area. The Sulphur River's course is characterized by wide bends, oxbows, and numerous sloughs. The river's hydrology is regulated by several dams and reservoirs, including Wright Patman Lake and Lake O' the Pines. These reservoirs provide water for recreational activities such as fishing and boating, as well as irrigation for agriculture. The Sulphur River has a rich history, as it was an important transportation route for Native American tribes, early settlers, and steamboat traffic during the 19th century. Today, the river is home to diverse wildlife, including the endangered Texas horned lizard and the bald eagle.
