The Embarras River (pronounced "EM-brah" or "AM-brah" ) is a tributary of the Wabash River, 185 mi (298 km) long, in southeastern Illinois in the United States. The waters of the Embarras reach the Gulf of Mexico via the Wabash, Ohio, and Mississippi Rivers. The river drains a watershed of approximately 1,566,450 acres (2,440 sq mi/6,320 km²) in an agricultural region. The name comes from French explorers, who used the term embarras for river obstacles, blockages, and difficulties relating to logjams and the like.
