By mid-June 2009, the rare filling of this lake in Australia’s Simpson Desert appeared to have reached its peak.
Published Jun 21, 2009Straddling Austria and Hungary, the lake is also known as the “Sea of the Viennese.”
Published Apr 10, 2017Sitting atop the Andes plateau on the border between Peru and Bolivia, the lake is the highest major body of navigable water in the world and the largest lake in South America.
Published Nov 23, 2015Long and short. Deep and shallow. Salty and fresh. Blue and brown. These are Africa’s Lake Tanganyika and Lake Rukwa.
Published Jun 20, 2019Lake Poopó sits high in the Bolivian Andes, catching runoff from its larger neighbor to the north—Lake Titicaca (not shown)—by way of the Desaguadero River, which is the muddy area at the north end of the lake. Because Lake Poopó is very high in elevation (roughly 3,400 meters, or 11,000 feet above sea level), very shallow (generally less than 3 meters, or 9 feet), and the regional climate is very dry, small changes in precipitation in the surrounding basin have large impacts on the water levels and area of Lake Poopó. When the lake fills during wet periods, it drains from the south end into the Salar de Coipasa salt flat (not shown). Water levels in Lake Poopó are important because the lake is one of South America’s largest salt-water lakes, making it a prime stop for migratory birds, including flamingoes.
Published Apr 24, 2006Floodwaters have worked their way through a series of parched channels, watering holes, and lagoons to start filling the iconic Australian lake.
Published May 28, 2019The Great Salt Lake of northern Utah is a remnant of glacial Lake Bonneville that extended over much of present-day western Utah and into the neighboring states of Nevada and Idaho approximately 32,000 to 14,000 years ago. The north arm of the lake, displayed in this astronaut photograph from April 30, 2007, typically has twice the salinity of the rest of the lake due to impoundment of water by a railroad causeway that crosses the lake from east to west. The causeway restricts water flow, and the separation has led to a striking division in the types of algae and bacteria found in the north and south arms of the lake.
Published Jul 16, 2007Drought conditions have dried this closed-basin lake straddling the California-Oregon border, but it’s not the first time.
Published Aug 12, 2015Surging with fresh water from heavy winter snow melt, Lake Powell rose significantly in the summer of 2011 after many years of low levels.
Published Aug 12, 2011In the desert, a lake shows a long fight between water, wind, and climate.
Published Feb 20, 2012In May 2016, the reservoir behind Hoover Dam reached its lowest level since the 1930s.
Published May 27, 2016Pyramid Lake, in western Nevada, is a remnant of the ancient and much larger Lake Lahontan that formed during the last Ice Age.
Published Oct 18, 2010Lago de Valencia (Lake Valencia) is located in north-central Venezuela and is the largest freshwater lake in the country. The lake was formed approximately 2-3 million years ago due to faulting and subsequent damming of the Valencia River. The lake has been completely dry during several discrete periods of its geologic history. Since 1976 Lake Valencia water levels have risen due to diversion of water from neighboring watersheds—it currently acts as a reservoir for the surrounding urban centers (such as Maracay).
Published Nov 22, 2004Meltwater from glaciers to the east and west drains into Lake Morari, a large lake that lies at an altitude of 4,521 meters (14,830 feet) on the Tibetan Plateau. A stream on the west side provides the lake’s main inflow. Mud from this river gives the light blue hues to the lake water. The well-formed alluvial fan (image center), built by sediment from the main inflow river, is the reason the lake has formed at this point in the valley.
