Lake Cisne in Colombia completely dried out in 2014 due to the effects of climate change. Using treated wastewater, the environmental authorities slowly refilled the lake over the course of 18 months. The lake is now fully restored and the surrounding fauna has returned to its shores. A new park has been built for the community to enjoy the wetlands and learn more about this incredible project.

 This short documentary tells the story.
