Calima Lake (Spanish: Lago Calima) is the largest artificial lake in Colombia with an area of 70 km². It is located in the municipality of Darién in the Valle del Cauca Department.
The lake is part of a hydroelectric project for generating power for the department. C.V.C (Corporación Autónoma Regional del Valle del Cauca) started construction of the lake by 1961.
Calima Lake has become a place for water sports and leisure activities. Vacation centers, restaurants and camping zones were built near the lake, and is currently a popular place frequented by both national and international tourists, especially those from nearby cities and towns like Cali and Buga. The elevation of the lake is 1500 meters (4950 feet) above sea level.
