Five Major Rivers of Nicaragua

Nicaragua's hydrology is dominated by large rivers draining to the Caribbean (most) and Pacific (few):

1. Río San Juan – Forms part of Nicaragua–Costa Rica border. Flows from Lake Nicaragua (Cocibolca) to Caribbean. Historic transit route (pre-canal).
2. Río Coco (Segovia) – Longest river entirely in Central America (750 km). Forms Nicaragua–Honduras border. Drains to Caribbean. Miskito indigenous heartland.
3. Río Grande de Matagalpa – Drains central highlands (Matagalpa, Jinotega coffee zone). Flows east to Caribbean. Major hydro potential.
4. Río Escondido – Southern Nicaragua. One of few Pacific-slope rivers. Drains Rama/Kukra Hill region. Shorter, steep gradient.
5. Río Rama – Southeastern lowlands. Meanders through Indio Maíz Biological Reserve to Caribbean. Critical for rainforest connectivity.

Lake Nicaragua (8,264 km²) and Lake Managua (1,042 km²) are the region's largest lakes—both drain via San Juan system.
