dam

At least seven have been built here over the past two years, including one by a small dam that regulates Sergele's water supply, rendering it off limits to villagers.

Over decades, the dams and increased diversions also took an environmental toll, drying up much of the once-vast wetlands in Mexico’s Colorado River Delta.

After a militant attack in Indian-administered Kashmir in 2016, Indian water resources ministry officials had told the BBC they would speed up construction of several dams and water storage projects in the Indus basin.

During the severe 2020-22 drought, the water flowing from dams sometimes got so warm that it was lethal for salmon eggs.

As competition for water intensified, “demands by powerful farmers and urbanites drove costly infrastructure projects such as dams. The ultimate result was the draining of the Colorado River Basin.”
