Ozama River

The Ozama River flows through the Dominican Republic. It rises in the Sierra de Yamasá mountain range, near the town of Villa Altagracia, on the Loma Siete Cabezas mountain.

Before emptying into the Caribbean Sea, the river flows 148 kilometers (92 miles). It divides the capital, Santo Domingo, into eastern and western halves at the end of the journey. The Isabela River, Sabita River, and Yabacao River are the three main tributaries of the Ozama.

The Ozama basin is the Dominican Republic's fourth largest. The river has several tributaries totaling 2,706 square kilometers in area (1,045 sq mi). The annual precipitation in the river basin ranges from 1,400 mm (55 in) to 2,250 mm (89 in).

The Ozama River has become severely polluted. The slums on its shores and the factories that dump their waste into it have a constant impact on it. It is one of the primary sources of pollution on Santo Domingo's coastline.
