Atacama - Lautaro Reservoir

 deutsch / español / english

Tranque Lautaro - Lautaro Reservoir:
Built in 1930 to ensure water supply in the Copiapó Valley and to eliminate probable flooding after heavy rainfall. The gate is located at 1130 meters high and captures the waters of the rivers Potro, Manflas, Jorquera, Chacay, Vizcachas del Pulido (or simply "Pulido") and Río Ramadillas.

Especially in river systems with high variability of their flow rate during the year reservoirs are a good measure to regulate the flow of water, specifically achieved a leveling of the flow rate throughout the year.
The disadvantages are the high rate of evaporation of water in the reservoir (especially in arid zones), consumption of landscape, the productive base of the valley disappears under the reservoir forever. In addition, the ecosystem downstream of the reservoir will be changed considerably due to the lack of replenishment of new sediments.
The last one, the sediments carried in the river water are one of the biggest problems in the reservoirs: due to the slower flow velocity, sedimentary load accumulates at the bottom of the reservoir. The reservoir is filled with sediment over decades and loses its original capacity. This phenomenon is more important in river environments defined by high variations of sporadic flows. Erosion and particle transport are increased in these sporadic events considerably. The other thing that can increase the load of suspended sediment in a river considerably is of course the lack of vegetation.
