<Tr> <Th_colspan="2"> Ramsar Wetland </Th> </Tr> <Tr> <Th> Designated </Th> <Td> 11 July 2002 </Td> </Tr> <P> Lake Poopó (Spanish: Lago Poopó Spanish: (ˈlaɣo po. oˈpo)) was a large saline lake located in a shallow depression in the Altiplano Mountains in Oruro Department, Bolivia, at an altitude of approximately 3,700 m (12,100 ft). Because the lake was long and wide (90 by 32 km, 56 by 20 mi), it made up the eastern half of the department, known as a mining region in southwest Bolivia . The permanent part of the lake body covered approximately 1,000 square kilometres (390 sq mi) and it was the second - largest lake in the country . The lake received most of its water from the Desaguadero River, which flows from Lake Titicaca at the north end of the Altiplano . Since the lake lacked any major outlet and had a mean depth of less than 3 m (10 ft), the surface area differed greatly on a seasonal basis . </P> <P> In 2002 the lake was designated as a site for conservation under the Ramsar Convention . By December 2015, the lake had completely dried up, leaving only a few marshy areas . Although the lake has dried up completely a couple of times in the past, it does not appear that it will recover this time . Suggested causes of the decline are the melting of the Andes glaciers and loss of their waters, because of a drought due to climate change, as well as continued diversion of water for mining and agriculture . </P>
