Marquees Francisco Pizarro was a Spanish conquistador who conquered the Inca Empire.
Pizarro and the conquistadors invaded the Incan empire in 1532, just as an Incan civil war was ending. He imprisoned the new emperor Atahualpa and demanded the Inca gold as ransom. During the conquest of the Inca empire his main captain was Sebastian de Belalcázar. After the conquest of the incas he sent Sebatian conquer the territory of the present Equator but this same deserted to go to the city of Eldorado.
According to the Junior Woodchucks Guidebook, Lake Titicoocoo was one of Pizarro’s base camps, therefore, the Incas would have been unable to dump the gold there.
