The Limón 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 project will help produce 4,000 gigawatt-hours (14,000 TJ) of electricity per year and transfer water from the Cajamarca region west to Lambayeque, near Olmos for the reclamation and irrigation of 43,500 hectares (107,000 acres) of farmland.
