Sabine Lake is a 90,000-acre (36,000 ha) salt water estuary on the Texas-Louisiana border. The lake, some 14 miles (23 km) long and 7 miles (11 km) wide, is formed by the confluence of the Neches and Sabine rivers. Through its tidal outlet 5 miles (8 km) long, Sabine Pass, Sabine Lake drains some 50,000 square miles (100,000 km²) of Texas and Louisiana into the Gulf of Mexico. The lake borders Jefferson County, Texas, Orange County, Texas, and Cameron Parish, Louisiana.
