The Manatí River (Spanish: Río Grande de Manatí) is a river in Puerto Rico, which flows through several northern municipalities of the island. The river is named after the municipality of Manatí where the river mouth is located.

Description

The river travels in sequence through Barranquitas, the municipal boundaries of Orocovis, Corozal and Naranjito, Ciales, Morovis, Barceloneta and Manatí in Puerto Rico. The river flows into the Atlantic Ocean in the municipal boundary between Barceloneta and Manatí.

History

In the 1898 Military Notes on Puerto Rico by the U.S. it is written that the "Manatí River is bounded on the east 'south by the Sierra Grande and on the west by the Siales ridge. It rises in the Sierra Grande, and parallel with the preceding river, it flows through Siales and Manatí, to the north of which latter town it empties into the Atlantic."^[1]
