The Atibainha dam in Brazil, part of the Cantareira reservoir, has been hit by a drought in Nazare Paulista, Sao Paulo state. It is the area’s worst drought in 80 years and has left the Cantareira system, which provides greater Sao Paulo with most of its water, with the lowest water level on record.

Lake Mead At Historic Low Levels As Drought Continues In Western US...LAKE MEAD, NRA, NV - JULY 17:  A boat sails on Lake Mead on July 17, 2014 in the Lake Mead National Recreation Area, Nevada. Last week, North America's largest man-made reservoir dropped below 1,082 feet above sea level, the lowest it's been since the Hoover Dam was built in the 1930s. A 14-year drought in the Southwestern United States and a dwindling supply of water from the Colorado River, in part due to cuts in the reservoir's annual allocation of water from Lake Powell, has left a white "bathtub ring" of mineral deposits left by higher water levels on the rocks around the lake as high as 130 feet. The National Park Service has been forced to close or extend boat launch ramps, and move entire marinas to try to keep up with the receding water levels.  (Photo by Ethan Miller/Getty Images)

Petong (C) and Hue (R) look for gold as their children play in the water on March 25, 2014 in Lampang, Thailand. Thai villagers from Wang Nuea, North of Thailand, look for gold in the river every year during the drought season. They are able to make an average around USD 15 per day, however two years ago they reached USD 200 in one day due to the river level dropping so much. The workers begin to search for gold at 10 AM and work until sunset, often working second jobs in the day in order to survive.
