The Río Patía is a 430 km long tributary of the Pacific Ocean in southwest Colombia .

Source rivers

The Río Patía arises at the confluence of the Río Esmita and Río Timbío in the Departamento del Cauca on the municipal boundary of Patía and El Tambo at an altitude of about 630  m .

The Río Timbío , the right source river, is 67 km long. It rises 10 km east of the small town of Timbío ( ⊙ ).

The Río Esmita rises near the village of Rosas at an altitude of about 1700  m ( ⊙ ). It flows mainly in a westerly direction and meets the Río Timbío after 50 km.

River course

The Río Patía initially flows 115 km in a south-southwest direction. It takes in the rivers Río Guachicono and Río Mayo , both coming from the east. Between the two junctions, the Río Patía forms the border between the Departamento de Nariño in the west and the Departamento del Cauca in the east. Then the river runs in the Departamento de Nariño. The Western Cordillera rises to the west, and the Central Cordillera runs further east . At rivers 317 and 310, the two rivers Río Juanambú and Río Guáitara come from the south and meet the Río Patía, which flows a few kilometers to the west. This then turns towards north-northwest and cuts through the mountain range of the Western Cordillera for a length of about 70 km. Finally he reaches the coastal lowlands and turns west. At river kilometer 137 the Río Telembí meets the Río Patía coming from the south. This now turns to the north.

River bifurcation and estuary arms

The Río Patía originally flowed into the sea in a wide river delta . In 1972 and the following years the river changed its mouth. He formed a canal to the Río Sanquianga, which flows further north . Today a large part of the water flows over this into the sea. From the bifurcation point ( ⊙ ) this newly formed main estuary runs 66 km to the north and reaches an estuary east of the actual river delta . On this section of the river he passes the small town of Bocas de Satinga . The Parque Nacional Natural Sanquianga extends over the estuary. From the bifurcation point, a smaller arm of the river branches off to the southwest today. After 20 km this branch of the river turns to the southwest and south. Several mouth arms branch off to the right. Finally, this southernmost estuary reaches the sea at Salahonda after a flow distance of 73 km ( ⊙ ).
