The Rio de la Plata is the longest river in the island of Puerto Rico. It is located in the north coast of the island. It flows from south to north, and drains into the Atlantic Ocean about 11 miles (18 km) west of San Juan. The mouth of the river is a resort area with white sandy beaches.
La Plata has a length of approximately 60.5 miles (97 kilometers) with its origin in the municipality of Guayama, Puerto Rico, at an altitude of approximately 2,625 feet (800 meters) above sea level. It crosses the municipalities of Guayama, Cayey, Comerío, Naranjito, Toa Alta, Toa Baja, and Dorado forming two lakes on its path: Carite Lake and La Plata Lake.
There are many crossings of the river. The Arenas Bridge, in Cayey, is one of the most notable. It is a steel bridge built in 1894 and is still in use. It was the longest bridge built in Puerto Rico by the Spanish.
The United States Army Corps of Engineers is undertaking a major flood control project in the river basin.
History
