The Río Cañar , in the upper reaches of the Río Huayrapungu , is an approximately 145 km long tributary of the Pacific Ocean in Ecuador .

River course

The Río Cañar rises in the Cordillera Occidental at an altitude of about 3900  m . It initially flows 20 km in a south-south-west direction. Then the Río Cañar turns west. North of the river is the small town of El Tambo , south of the small town of Cañar . The Río Cañar flows through the province of Cañar in a westerly direction. After almost 90 kilometers the river reaches the coastal plain. The rivers Río Patul , Río de Piedras and Río Norcay flow into the Río Cañar from the south. At river kilometer 50 the Río Cañar reaches the province of Guayas . Finally the Río Cañar flows into the Gulf of Guayaquil . The estuary is in the Manglares Churute nature reserve .

Hydrology

The Río Cañar drains an area of ​​2384 km². The mean discharge is 53 m³ / s.

Use of hydropower

Ocaña hydropower plant

The Ocaña hydropower plant ( ⊙ ) is located at river kilometer 63 on the Río Cañar, just under 14 km southeast of the city of La Troncal . It was built between March 2009 and January 2012. A 5 m high and 37.2 m long weir ( ⊙ of the Creager type, 0.537 m³ / s ecological-related minimum discharge) is located 8.4 km upstream at an altitude of 845  m . It has a 55 m long fish ladder . A 157 m long low-pressure water pipe (1.9 m Ø), a 6390 m long tunnel, a 42.6 m high water tower (3.8 m Ø) and a 1085 m long pressure pipe (1.9–1.6 m Ø) feed the water to the 455  m high power station. This has two vertical Pelton turbines of 13 MW each. The fall height is 373 m. The expansion water volume is 8.2 m³ / s. The two units deliver an electrical voltage of 13.8 kV, which is then stepped up to 69 kV.
