Dowleswaram Barrage
The 928th tallest dam in the world
The Dhawaleswaram Barrage was an irrigation structure originally built in 1852 by Sir Arthur Cotton on the lower stretch of the Godavari River before it empties into the Bay of Bengal. Retrofitting was done in 1970, and it was officially renamed as Sir Arthur Cotton Barrage, also known as Dhawaleswaram Barrage.
