The Yuna River (Spanish: Río Yuna) is the second longest river in the

Cibao Valley.[3] As the river courses north-northeast, it passes through the city of Bonao. Southwest of Cotuí, the river reaches Hatillo Dam (Spanish: Presa de Hatillo) before turning northeast then east as it reaches its mouth at the Samaná Bay in the northeast part of the Dominican Republic.[4] Like many rivers in the Dominican Republic, the name is derived from the Taíno language.[5]

Course

The source of the Yuna is located 78.95 km (49.06 miles) southeast of the city of Santiago and 62.41 km (38.78 miles) northwest of the city of Santo Domingo.[6] The source is located near the southern Monseñor Nouel village of La Cuesta de la Vaca within the municipality of Bonao on Cerro Montoso Hill (Spanish: Loma de Cerro Montoso) at an elevation of 1,075 m (3,527 feet) above sea level. The Cerro Montoso Hill lies along the highest mountain range in the West Indies, the Cordillera Central. The Cordillera Central provides the principal watershed and drainage divide for the Dominican Republic; the Yuna has its source along the northern slope of the mountain range.[7] The Yuna descends from its headwaters running south then west where several streams feed into the river near the San José de Ocoa province border. The Yuna then turns north near the village of El Torito passing through several mountains including Torito Hill (Spanish: La Loma del Torito), and Middle Hill (Spanish: La Loma El Medio). The Yuna shifts north-northwest near the Middle Hill passing through several villages including Pino de Yuna, Piedra de los Veganos, and El Capa.[8]

The Yuna next flows into the village of Los Finitos where it travels in a more northerly course. The river then receives two tributaries along its left bank: the

Autopista Duarte before entering another mountainous region of Monseñor Nouel. The Yuna next passes north of Falconbridge Ltd., a major economic income for the Bonao area. The Yuna heads east as it cuts through several mountains in this region including the Flat Hill (Spanish: La Loma del Llano) where the Yujo River converges onto the Yuna. The river accompanies the Sánchez Ramírez Province line east of Flat Hill and enters the province upon arriving at Lake Hatillo (Spanish: Presa de Hatillo) in the municipality of Cotuí where it joins the Maimón River.[9][10]

Lake Hatillo runs north-northeast for 15.46 km (9.61 miles) and has a total area of 27.94 km2 (11 square miles) from the Yuna–Maimón convergence to a

Eugenio Maria de Hostos where it meets two small tributaries along its left bank: the Nigua and Yaiba Rivers.[10][13]

The Yuna next heads into the municipality of

Sánchez and 10.26 km (6.38 miles)[17] north of the Barracote River mouth. The delta is located within the Lower Yuna Mangroves (Spanish: Manglares del Bajo Yuna) and empties into the Samaná Bay.,[18][19][20][21] which is one of the largest estuaries in the Caribbean.[22] There is a long period when the Yuna River provides Samana Bay with a flow of stable and low freshwater, as well as two times of the year when the Yuna River rises and provides the Bay with a flow of large freshwater.[23] In total the Yuna River, is 208 km long.[22]

Rice irrigation

A primary use of the Yuna River, as it flows along the city of Bonao, is for rice cultivation.

As noted by Barzman and Peguero (1995) in their work 'Impacts of Altered Freshwater Flows to Estuaries: Yuna River Watershed and Samana Bay' (Jim Tobey, 2004), 'agrochemical use for rice cultivation in the Yuna watershed is contributing to loss in soil fertility and to increases in pests, weeds, and diseases. Consequently, this requires further increases in the already high use of the same agrochemicals.' (Tobey, 2004, 31)[24]

Geology

Although most of the Yuna River bed is vegetated, but there is a high amount of gravel south of Bonao.[25]
