Limon Dam
Encyclopedia
The Limon Dam, part of the Olmos Transandino Project, is an under construction multi-purpose concrete-face rock-fill embankment dam
on the Huancabamba River
in northwestern Peru
, located to the south of Guabal. When completed, the dam
will help produce 4,000 GWh of electricity per year and transfer water from the Cajamarca
region west to Lambayeque
, near Olmos
for the reclamation
and irrigation of 150,000 hectares of farmland

tunnel to the Olmos Valley. The Limon Dam will be an 43 metres (141 ft) high, 320 metres (1,050 ft) long embankment dam and when full, it will withhold a reservoir of 44000000 cubic metre. In addition, the dam will house a hydroelectricity
power plant with a 600 MW capacity. The greatest feature and engineering challenge of the project was the deep trans-Andean tunnel as it connects the Atlantic side of the Andes (Amazon Basin
) with the Pacific side.
