The Río Pisco is an approximately 106 km (including Río Chiris : 186 km) long tributary of the Pacific Ocean in the southwest of Peru in the regions of Huancavelica and Ica .
River course
The Río Pisco arises in the Peruvian Western Cordillera at an altitude of about 1700 m near the town of Ticrapo at the confluence of the Río Chiris (right) and Río Pacococha (left). The main source river is the 80 km long Río Chiris. Its origin is the 4690 m high lake Laguna Pultoc Grande ( ⊙ ). The Río Pisco flows through the mountains over a length of about 60 km, initially 25 km in a south-south-west direction, later in a west-south-west direction. In the lower 45 kilometers, the river crosses the arid, desert-like coastal plain in a westerly direction. It is bordered by irrigated agricultural areas. The Panamericana Sur crosses the river near the small town of San Clemente , about 8 kilometers above the estuary . At the lower reaches of the Río Pisco there are several weirs at which irrigation channels branch off. The river carries very little water for the last few kilometers. It finally reaches the Pacific coast north of the provincial capital Pisco . There it flows into a lagoon, which is almost completely separated from the sea by a sandbank.
Catchment area and hydrology
The catchment area of the Río Pisco covers an area of 4434.5 km². In the north the catchment area borders on that of the Río San Juan , in the south on that of the Río Ica . The mean discharge at the Letrayoc gauge ( ⊙ at river kilometer 55, located at an altitude of 630 m ) is 25.68 m³ / s. During the rainy season, the river carries most of the water in the year.
