The Dajabón River, locally known in some sources as the Río Dajabón or Río Masacre, is a short coastal river on the northern side of the Cordillera Central in the Dominican Republic. It runs roughly 55 km from its headwaters in the highlands northward and discharges into the Atlantic Ocean at Manzanillo Bay. The river is a prominent feature of the northwest Dominican landscape and figures in local geography and cross-border relations. More on the river

Geography and physical characteristics

The river originates on the northern slopes of the Cordillera Central and follows a generally northerly course to the coastal plain. Along its path it descends from steep, forested terrain onto more cultivated land before reaching Manzanillo Bay on the Atlantic coast. The Dajabón drains a compact watershed and exhibits marked seasonal variation, with higher flows during the Caribbean wet season and tropical storms. Manzanillo Bay marks its marine outlet.

Names, border role and history

The watercourse is referred to by more than one name in maps and historical accounts. The alternative name "Masacre" appears in older colonial-era documents and maps; explanations for that name vary among historians. In stretches the river marks or approaches the international boundary between Haiti and the Dominican Republic, and the valley around the river has long been a focus of settlement, trade and political attention. For background on the national setting see the Dominican Republic.

Uses, communities and economy

Communities along the Dajabón depend on it for small-scale irrigation, local fishing and as a water source for livestock. The town of Dajabón lies near the river's northern reaches and hosts a well-known cross-border market where people from both sides interact weekly. Bridges and fords on the river are important local transport links and commercial nodes.

Environmental issues and notable facts

Like many rivers on Hispaniola, the Dajabón faces pressures from land use change in its watershed: deforestation, agricultural runoff, sedimentation and occasional sand extraction. These factors affect water quality, habitat and flood behaviour. The river's international setting means that any conservation or water-management measures benefit from cross-border coordination and local stakeholder involvement.
