List of rivers in Puerto Rico (U.S. Commonwealth), sorted by drainage basin and then alphabetically. There are 47 main rivers and 24 lagoons or reservoirs.[1]
Most of Puerto Rico's rivers originate in the Cordillera Central. There are four slopes through which rainwater flows towards the sea. According to their orientation they are known as the north or Atlantic slope; southern slope or the Caribbean Sea; the east slope of the Virgin Passage and the Sonda de Vieques and the west slope or the Mona Passage. Due to the generally abundant rain and the flow of its water currents, the most important rivers of Puerto Rico slide down the north slope. Taíno and native people normally built their communities near the rivers. During the Spanish colonization era, the same was true with many pueblos being founded near rivers.[2]
There are about 5,385 miles of river in Puerto Rico; 224 rivers and 553 named streams.[3][4][5][6] Only 8.9 miles of Puerto Rico's rivers have the official U.S. Wild and Scenic River Designation.[7]
