Term River
Definition

A water stream that flows continuously, has a determined water level and empties into another stream, lake or sea. It erodes the surface with its flow, giving way to the formation of valleys, the cutting of canyons, or the deposit of  materials which cause the formation of floodplains. Rivers bring water and nutrients to both plants and animals; they also transport organisms and reproductive structures. Humans use them for, among other things, water supply, fishing, transportation, and waste disposal, as their water regenerative power is high.

Some Dominican rivers are unique in that they have a dry riverbed during the dry season, they increase their volume in the rainy season, and in some cases even rise to become highly destructive currents. This feature makes it difficult to use them for agriculture.

The rivers of the Dominican Republic are divided into two groups, depending on their relationship to the two main river basins of the country: the northern basin and the southern or Caribbean basin.

The following rivers are found in the northern river basin: Dajabón (Masacre), Bajabonico, Camu del Norte, Joba, San Juan, Boba, Nagua, Yabón, Yaque del Norte, with its tributaries Guayubín, Mao, Amina, Bao and Jimenoa; Yasica, with its tributary Jamoa; and the Yuna river, whose tributaries are Camú, Masipedro, Maimón, Chacuey, Payabo, Jaya, and Cuaba.

The following rivers are found in the southern river basin: Yuma, Chavón, Dulce, also known as Romana; Soco with its tributary Seibo; Macorís, with its tributaries Casuí, Magua, and Iguamo; Ozama, with its tributaries Yabaco, Isabela, Jaima, Nigua, Nizao, Bani, Ocoa, Via, and Tabara; and Yaque del Sur, with its tributaries Las Cuevas, Grande or del Medio, San Juan and Bao; and Pedernales.

The Yaque del Norte river is considered the most important in the country because it has the highest volume. It begins in Pico del Yaque, on the Central Mountain Range, and runs 296 kilometers, ending near Monte Cristi in the northwest. Its main tributaries are Jimenoa, Bao, Amina, Mao, Guayubín and Maguaca.

The second largest river is the Yuna, which runs 197 kilometers from the Montes Banilejos to Samaná Bay, where it ends. In its trajectory, it passes through the Cibao Valley. Its tributaries are Camú, Masipedro, Maimón Chacuey, and Cuaba.

The Yaque del Sur river runs 186 kilometers from the Loma La Rucilla to the Neyba Bay. It is the river which initiates at the highest altitude in the country, at about 2.707 meters above sea level. Its main tributaries are San Juan, del Medio, and Las Cuevas.

The Artibonito river is the longest on the island, but it flows into the Republic of Haiti, covering about 119 km of Dominican territory. It begins in the Central Range and flows into the Gulf of Gonaive, for a total journey of 321 kilometers. Its Dominican river basin is 2.614 square kilometers, of a total basin of 9.013 square kilometers, the biggest on the island. Its tributaries are Macasía, Libón, which initiates in Haiti, and Joca. The Macasía and Libón rivers mark the border with Haiti.
