Quick Summary

The Neuquén River is a significant waterway in western Argentina. It originates in the Andes Mountains near the Chilean border and flows eastward. The river is approximately 320 miles (515 km) long, though some sources state its length is about 400 miles (640 km) or 700 miles (1,125 km) when including its headstream, the Neuquén.12

The Neuquén River meets the Limay River at Neuquén city, and together they form the Negro River, which then flows into the Atlantic Ocean. The waters of the Neuquén River are utilized for hydroelectric power and irrigation, supporting the cultivation of grains and fruits like grapes and apples. The river also plays a role in the province of Neuquén, contributing to irrigated valleys that are important for income.134
