The two upper forks of the Sabine River, the South and Cowleech Forks, are formed in eastern Collin County and northwestern Hunt County respectively. These two forks meet in Hunt County forming the main stream which flows southeast through pine woods for approximately 555 miles, partially forming the boundary between Texas and Louisiana. The river then empties into the Gulf of Mexico at Sabine Lake. The Sabine has the largest volume of water discharged (approximately 6,800,000 acre-feet) at its mouth of any river in Texas. The word "Sabine" comes from the Spanish word for "cypress," referring to the stately trees which line the banks of the river.
Two large reservoirs have been constructed on the Sabine. Lake Tawakoni in Hunt, Rains, and Van Zandt Counties, is a water storage reservoir which largely controls the upper portion of the river. Lake Tawakoni has been constructed at the junction of the South and Cowleech Forks. Toledo Bend Reservoir, a huge impoundment located along the Texas and Louisiana border, controls the lower Sabine River.
