The San Juan River, also known as El Desaguadero ("the drain"), is a 192-kilometre (119 mi) river that flows east out of Lake Nicaragua into the Caribbean Sea. A large section of the border between Nicaragua and Costa Rica runs on the right (southern) bank of the river. It was part, with the lake, of a proposed route for a Nicaragua Canal in the 19th century. The idea of the project has been revived in the last decade, including the possibility of other routes within the country. The Ecocanal project has obtained a Concession from the National Assembly of Nicaragua to re-open the San Juan River to commercial barge traffic.
