Here’s how Kerala’s dams worsen the once-in-century floods

More than 5 million people in Kerala were affected and over 200 were killed amid torrential rain and floods in August. The flooding, dubbed the worst to hit the southern state in nearly a century, caused billions of dollars of damage to fields, homes and other infrastructure.

As the rain intensified in mid-August state authorities were forced to release water from 35 dams to manage rising waters in reservoirs, many of which are used to generate hydroelectricity.

State government officials say the severity of the flooding was due to a once-in-a-century storm that could not reasonably have been prepared for, and that the spilling of dam water had little impact.
