Sulphur River Basin

Texas map showing Sulphur river basin outlinesThe Sulphur Basin has the largest average watershed yield of any major river basin in Texas because of the region's high precipitation and low evaporation rates.  From the confluence of the North and South Sulphur rivers in East Texas, the Sulphur River flows to its confluence with the Red River in Arkansas.

Smaller streams in the basin include the North, Middle, and South Sulphur rivers and White Oak Creek.  Because the Sulphur River is a tributary of the Red River, surface water within the basin is apportioned by the Red River Compact between Texas, Oklahoma, Arkansas, and Louisiana.  The basin is an important source of surface water supply for surrounding regions.  Balancing environ-mental needs with continued development of surface water supplies is an issue in the basin.
