The Limón Dam, part of the Olmos Transandino Project, is a multi-purpose concrete-face rock-fill embankment dam on the Huancabamba River in northwestern Peru, located to the south of Guabal. The project helps 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. The greatest feature and engineering challenge of the project was digging the 20-kilometre (12 mi) trans-Andean tunnel as it connects the Atlantic side of the Andes (Amazon basin) with the Pacific side.
The Olmos Irrigation Project is the largest of seven irrigation projects in Peru.
