Río Inabón

Río Inabón is one of one of the 14 rivers in the municipality of Ponce, Puerto Rico. With a length of some , it is Ponce's second longest river after Río Jacaguas. It is fed by the Río Anón, Río Guayo (which itself is fed by the Chiquita Brook and the Indalecia Brook) and the Emajagua Brook. It is also fed by Río Bacas and Río de las Raices. Originating at an altitude of approximately , it forms at a higher altitude than any of the other 13 rivers in the municipality, and at one of the highest points of any river in Puerto Rico. With a watershed area covering 38.18 square miles, Río Inabón also has the second largest basin area of any of the municipality's 14 rivers after Río Jacaguas.

Origin and course

Río Inabón has its origin at above sea level in Cerro Camacho, in barrio Anón, near Anón's boundary with the municipality of Jayuya. The river runs mostly parallel to PR-511.

Uses

"A provision in The Treaty of Paris of 1898 grants the Serrallés family exclusive rights to the Río Inabón. This river winds through Puerto Rico’s volcanic mountains, and is the exclusive water source for DonQ Rum". Today Río Inabón is one of the most popular rivers for swimming in southern Puerto Rico. Some 10 private reservoirs in the Ponce area are fed by the waters of Río Inabón.

Environmental contamination

In January 2011, Puerto Rico Representative Víctor Vassallo Anadón presented a bill into the Puerto Rico House of Representatives that would improve the sewer system of residents near the river to avoid contaminating it with sewer waters.

Endangered species

The fern '' Thelypteris inabonensis'' found at the headwaters of Río Inabón and at the Toro Negro State Forest has been identified by the U.S. Fish and Wildlife Service as an endangered species.

Flow

The flow of water in the river is controlled by the floodgates at Toa Vaca Lake, located in the municipality of Villalba. Río Inabon has a discharge of 15,000 ft³/s. The Inabón has been known to overflow easily in times of heavy rains. Several rescues have taken place when the river has increased its level rapidly, a phenomenon known as flash flood. Due to its proximity to the eastern end of Aeropuerto Mercedita, the river has affected the operation of the airport in times of heavy rains. This was the case with the hurricane Maria in September 2011.''Trastoca al sur remanente de María.''

Notes

:1.Google Maps incorrectly labels some of the northern portions of Río Inabón as Río Anón. This is most evident in portions just below where Rio Anón feeds into Rio Inabón. See HereWeGo Map

and MapQues

for labeling consistent with Government of Puerto Rico and USGS labeling.
