The Río Naya is an approximately 140 km long tributary of the Pacific Ocean in western Colombia . It runs largely along the border of the northern department of Valle del Cauca and the southern department of Cauca .

River course

The Río Naya rises in the Western Cordillera , about 40 km southwest of the city of Cali , at an altitude of about 2500  m . It initially flows 15 km to the west, then 10 km to the south and finally again to the west. At river kilometer 80 the Río Naya leaves the mountains and reaches the western Colombian coastal lowlands. It flows through this in a predominantly westerly direction. At river kilometer 15, near the village of Puerto Merizalde , a 15 km long estuary branches off to the left. This forms the border between Cauca and Valle del Cauca and ends ( ⊙ ) in the north of a bay into which the Río San Juan de Micay also flows. 11 km above the estuary, a 20 km long estuary branches off to the north ( ⊙ ), while the main estuary branches off to the west.

Hydrology and catchment area

The Río Naya drains an area of ​​around 1700 km². In the north the catchment area borders on that of the Río Yurumangui , in the south on that of the Río San Juan de Micay.

The mean discharge is 417 m³ / s. The catchment area of ​​the Río Naya lies in the humid tropical zone. This is characterized by tropical rainforest . The temperatures are relatively constant over the year. Furthermore, the climate is characterized by heavy rainfall and high humidity. The months of September to November usually see the highest rainfall on the Colombian west coast. In addition, there is a less pronounced rainy season between April and June.
