Natalia Points Gualliguaica, Chile. Natalia Edith Codoceo Flores points to the original village of Gualliguaica, where she lived until the 1990 s before it was flooded by the Puclaro Dam. A 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. Taken April 29, 2013.
