Overview

Cuba's rivers are generally short and seasonal compared with continental river systems, but they play an important role in the island's landscape, agriculture and biodiversity. Many rise in the interior highlands and run to either the north or south coast. The longest river is the Cauto; the Zaza is notable for its high discharge and reservoirs. For a comprehensive index consult available resources: more detailed listings.

Characteristics

Most Cuban streams drain small basins and are not navigable for long distances. Rivers supply irrigation, reservoirs, hydroelectric installations and municipal water. Several eastern rivers flow through protected forests and are valued for wildlife. Tributaries and smaller creeks strongly influence seasonal flow and flooding; for typical tributary patterns see tributary descriptions.

Selected rivers (arranged broadly west to east by coast)

The following is a selective listing of well-known Cuban rivers, organized roughly from the western end of the island to the east. It is not exhaustive but highlights principal streams and basins.

  • Western and Havana region
    • Mayabeque River
    • Almendares River (flows through Havana)
  • Matanzas and northern central coast
    • Yumurí River
    • Canimar River (Matanzas)
  • Villa Clara and north-central
    • Sagua la Grande
    • Sagua la Chica
  • Central interior / southern drainage
    • Zaza River (major central river, associated reservoirs)
    • Jatibonico rivers (regional streams with north and south branches)
  • Eastern Cuba
    • Cauto River (the island's longest)
    • Bayamo River
    • Toa River (noted for high biodiversity in its watershed)

Uses and significance

Cuban rivers are central to irrigation, local fisheries and urban water supplies. Several rivers form reservoirs that moderate seasonal shortages and provide hydroelectric power on a small scale. Rivers running through protected areas host diverse flora and fauna, and some valleys are noted for scenic and cultural importance.

Notable distinctions

Key distinctions include length (Cauto is the longest), discharge and reservoir development (Zaza basin), and ecological value (Toa basin in the east). Because of the island's geology and climate, many rivers have highly variable flows and their courses and use have been modified by dams and canals.
