The Nazca Valley is one of the driest places on earth receiving approximately 1 inch of rain per year. The water flow of the main river, the Rio Grande has not been enough to sustain the population of the Nazca region either in the past or present especially during times of drought. An aqueduct system built by the same people as constructed the Nazca Lines have allowed people to thrive in the harsh environment for over 2000 years.
