Drying Lake Poopó, Bolivia
"Lake Poopó, Bolivia’s second-largest lake and an important fishing resource for local communities, has dried up once again because of drought and diversion of water sources for mining and agriculture. The last time it dried was in 1994, after which it took several years for water to return and even longer for ecosystems to recover. In wet times, the lake has spanned an area approaching 1,200 square miles (3,000 square kilometers). Its shallow depth—typically no more than 9 feet (3 meters)—makes it particularly vulnerable to fluctuations."
