The remains of a car in Epecuen. Town comes up for air after 25 years under water Buildings lie in ruins. Epecuen was once home to 1,500 residents before it started flooding on November 10, 1985. After heavy rains the lake Epecuen burst its banks . It only took 20 days for the town to submerge beneath almost 10 meters of water, forcing everybody to leave. Amazing!
