River course
The Río Dagua has its source in the Western Cordillera . The headwaters, which are around 1800 m high, are 13 km west of Cali , on the western flank of the 2265 m high Cerro Montañitas . The Río Dagua initially flows 35 km north through the mountains. At river kilometer 95, the small town of Dagua is on the right bank of the river. The I-19 highway coming from Cali runs from Dagua along the river to Loboguerrero . There the trunk road meets the I-40 ( Buga - Buenaventura ), which then follows the river, which is now flowing in a westerly direction, up to river kilometer 52 for 30 km. The railway line ( Yumbo - Buenaventura) operated by Ferrocarril del Pacífico also runs along the river. The Río Dagua reaches the western Colombian coastal lowlands at around river kilometer 50. It runs south of the city of Buenaventura in a predominantly western direction. Buenaventura Airport is located 20 km above the estuary on the north bank of the river. The Río Dagua turns for the last 12 km to the northwest and finally flows into the Bahía de Buenaventura 2 km south of Buenaventura .
Hydrology and catchment area
The Río Dagua drains an estimated 1460 km². In the south the catchment area borders on that of the Río Anchicayá , in the north on that of the Río Calima , a tributary of the Río San Juan .
The mean discharge of the Río Dagua is 125 m³ / s.
