Sunken Forests: Periyar Lake
Located in Kerala, India, Periyar Lake is an artificial reservoir which was flooded after the creation of a nearby dam. The lake is a cemetery for a tree stumps that once comprised a forest.
Ghana’s Lake Volta was formed by the Akosomba hydroelectric dam and was completed in 1965.
It holds the world title for largest surface area of any reservoir and also maintains a hidden cache of dead trees – tropical hardwoods preserved by the lack of oxygen in the water – in its midst.
