La Esmeralda Dam is an embankment dam on the Batá River northwest of Santa María in Boyacá Department, Neira Province, Valle de Tenza (Tenza Valley) Colombia, 52 km to south of Tunja city. The primary purpose of the dam is hydroelectric power production and it is part of the Chivor Hydroelectric Project. Water from the Batá is diverted by the dam to a power station that discharges to the Lengupá River. The power station supplies 8% of Colombia's power demand.[2]
