The lake was formed in 1996 when a new hydroelectric dam was built on the San Juan and Tula Rivers. The power plant generates 292 megawatts per hour, not to mention creating a wealth of opportunities for outdoorsmen who enjoy boating and fishing on the peaceful waters. Weekend cabins can be rented on an island in the middle of the lake.
Church of St John the Baptist
Completed in 1822, this church is the most outstanding baroque-style in the Sierra Gorda region. Its façade contains extraordinary carved reliefs with the images of San Sebastián and San Jerónimo. The interior was crafted by indigenous stone masons who engineered the building to brilliantly light up the church with three beams of light at the moment of the summer solstice.
