San Juan (Nicaragua; rio)

"El río San Juan de Nicaragua es un río de Nicaragua de 200 km de longitud, que nace en el Gran Lago de Nicaragua o Cocibolca la Mar Dulce y desemboca en el mar Caribe. En su curso inferior, la margen derecha es durante un tramo frontera con Costa Rica."

"The San Juan (Spanish: Río San Juan), 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. The CañasJerez Treaty states that Nicaragua owns the waters of the river and that Costa Rica can only use it for commercial navigation on certain parts of the river at Nicaragua's discretion. Prior to the Panama Canal, the San Juan River was frequently used as a major part of the route from the Atlantic to the Pacific Ocean. Many people, including African slaves, were transported via this route. During the California Gold Rush, as many people from all over the world traveled to California to mine for gold, tens of thousands took a steamboat that was operated by the Accessory Transit Company and was directed by Cornelius Vanderbilt. The boat travelled up the San Juan River and across Lake Nicaragua; a stagecoach completed the connection to the Pacific coast. The San Juan River is home to freshwater bull sharks that also go into Lake Nicaragua in addition to a wide array of marine life and biodiversity. It is property of Nicaragua."
