After sitting chin deep in water for 17 days, villagers in central India succeeded on Sept. 10 in forcing authorities to reverse the recent increase in dam water threatening to submerge their land.

The flood destroyed one third of the township, and around 200 people are missing, according to villagers.

A dam collapsed in northern China, unleashing about 141 million cubic feet of water and decimating five villages downstream.

Dams lead to social and environmental problems that potentially affect an estimated 472 million people worldwide, say researchers.

A Washington State dam proposal that was first considered back in the 1920s and is now coming to fruition could have serious consequences for a British Columbia valley.
