A half mile to the west rises the Sabine River, lower channel of which separated New World empires of France and Spain and in 1836 became Republic of Texas - United States border. Fork here is called Cow Leach, for Indian chief who lived in the area. This marker is on a 3-way watershed: flow to the north goes into the Sulphur and to the Mississippi; the west drains to the Trinity; south goes into the Sabine, which forms Texas-Louisiana boundary and pours more water into Gulf of Mexico than any other Texas river (6,400,000 acre feet annually).
