Canóvanas RiverThe Canóvanas River is a tributary of the Loíza River that flows through the municipalities of Canóvanas and Río Grande, Puerto Rico.GeographyThe Canóvanas River is one of the primary tributaries of the Loíza River within the northern plains geographical region of Puerto Rico. Its headwaters originate on the northern slope of El Toro massif of the Sierra de Luquillo, within the boundaries of barrio Guzmán Arriba of Río Grande. These headwaters are protected as part of El Yunque National Forest, particularly within El Toro Wilderness. The river then flows northward, splitting the municipality of Canóvanas in half as it flows to the lower valley of the Loíza River. Its mouth lies just north of Canóvanas Pueblo, close to the former sugarcane plantation and refinery of Central Canóvanas.RecreationThere are numerous popular swimming areas along the river, for example, Charco Los Pilones and Charco de los Caballos are located in an area of stream pools located in the Lomas and Hato Puerco barrios of Canóvanas.
