Oropouche River (North)

The Oropouche River, specifically the North Oropouche, originates in the high elevations of Trinidad's Northern Range and flows eastward to empty into Matura Bay. This river system serves as a critical hydrological resource, feeding the Hollis Reservoir which provides potable water to much of the island. The surrounding landscape is characterized by rugged limestone karst topography, leading to the creation of extensive cave systems such as the Cumaca Cave. These caves are famous for hosting significant colonies of the nocturnal Oilbird (Steatornis caripensis), a species of scientific interest. The river's catchment area is a biodiversity hotspot, supporting diverse wildlife including red howler monkeys and various neotropical flora. Historically, the area was settled for small-scale agriculture and timber extraction during the colonial era. Today, it is recognized for its ecological sensitivity and its role in maintaining the island's groundwater levels.
