Primero River

The Primero River (in Spanish Rio Primero), also known as Suquia (the name used by the comechingones indigenous people), runs through the city of Cordoba, Argentina.

The tributaries of the Primero (mainly the San Roque and Cosquin rivers) flow into the San Roque reservoir; from there, the Primero goes east into the plains surrounding the city of Cordoba.

Once inside the city, the La Canada stream meets the Primero near the downtown area. Two kilometers to the east, Isla de los Patos (Ducks Island) was repopulated with ducks and swans in the 1980s. During the crisis years of 1988–1991 and 2001–2002, the duck population was devastated, allegedly by people desperately looking for food. It was reported in March 2006 that a large number of ducks had died due to unspecified causes [*]. Pollution by chemical waste is suspected as the cause, but avian influenza is also being investigated as a possible cause.

Beyond the city limits, the river flows towards the Algarrobos swamp and ends its course on the southern coast of the Mar Chiquita (or Mar de Ansenuza) salt lake. All in all, the river has a length of approximately 200 kilometers and carries, on average, 9.7 m/s, with minima of 2 m/s and maxima of 24 m/s [*] with a peak during the summer months.

Pollution of the water and of the riverbank is a major environmental issue in Cordoba. Periodic cleaning operations are carried out to increase the quality of the water and to preserve the viability of fishing, both in the San Roque reservoir area and downstream.

Note: The major rivers of Cordoba are named by means of Spanish ordinals: Primero, Segundo, Tercero ; their indigenous names are also used, notably in official documents and geography textbooks. Most people alternate between the two names on a convenience basis.
