Sanquianga River

The Sanquianga River (Río Sanquianga) is a river in the west of Colombia that flows into the Pacific Ocean.

Course
The river flows through the Nariño Department.

Climate
Temperatures average around 27 C. Annual rainfall is 3000 to 4000 mm. The most rain falls in June and July. November is the driest month.

Delta
There is a large river delta at the mouth of the Sanquianga that feeds an area of Esmeraldes-Pacific Colombia mangroves with water relatively high in sediment. The mangrove trees have a canopy that reaches 40 to 50 m in height. Sanquianga National Natural Park covers an area of the river delta which is periodically flooded by the action of the tides and rivers. It covers an area of 80000 ha in the municipalities of Mosquera, El Charco and Olaya Herrera. The Pacific tides carry the influence of the sea waters many kilometers into the interior of the low coastal plain.
