Estero Los Litres

The Los Litres estuary originates north of the city of Nogales and flows southward through it. Along its course, it runs past the southern slope of La Calera, where the cities of El Melón and Artificio are also situated.^[2]

The lower Aconcagua sub-basin extends from its confluence with the Pocuro estuary to the mouth of the Aconcagua River at the Pacific Ocean, and includes the Catemu estuary. Peak flows occur in December and January due to snowmelt, while lower flows are observed from March to May.^[3] An assurance level probability of 85% is used to determine available water flows for allocating permanent agricultural irrigation rights, ensuring a high level of investment security.^[4]
