Drought’s Ghosts Gualliguaica, Chile. The original village of Gualliguaica, where Natalia Edith Codoceo Flores lived until the 1990 s, was flooded when the Puclaro Dam was built. But the long lasting drought has diminished the reservoir to 10 % (or less) of it’s capacity. The entire old village is now exposed, as the “reservoir” essentially receded back to the original bed of the Elqui. She stands inside an old door frame of a once-submerged house.
