The Coamo River (Spanish; Castilian: Río Coamo) is a river in southern Puerto Rico. It runs for approximately 24 miles or 38 kilometers through the municipalities of Coamo and Santa Isabel, where it empties into the Caribbean Sea at Coamo Bay in Boca Velázquez. Its source lies in the Cordillera Central, on the Pulguillas ward (barrio).[1]
The Coamo River and its coastal wetlands host great egrets and other wildlife throughout the year. The river was dredged and cleaned after damages and flooding caused by Hurricane Maria in 2017.[2] It also contains irrigation dams, such as the Coamo Reservoir Dam in Santa Isabel.[3]
