Cumbum Lake

Cumbum Lake, also known as Gundlakamma Lake, is a historic artificial lake in Cumbum town, Prakasam District, Andhra Pradesh. Built in the 15th century on the Gundlakamma River, it is regarded as one of the oldest man-made lakes in Asia. Surrounded by the Nallamala Hills, the lake serves irrigation and drinking water needs and is noted for its large water spread, earthen dam and scenic setting.

Visitors can expect a large, calm water body with an earthen bund, views of the Nallamala Hills, and open lakeside areas for walking and photography. The lake has a tank bund road, boating point, and surrounding agricultural fields. The setting is rural and tranquil, with opportunities for sightseeing, birdwatching, and enjoying sunrise and sunset views over the water.

Cumbum Lake was constructed in the 15th century by Varadharajamma, wife of Vijayanagara ruler Deva Raya II, by building an earthen dam across the Gundlakamma River for irrigation. It has been in continuous use for over 500 years and is cited as one of the oldest surviving artificial irrigation tanks in Asia, later maintained and improved during subsequent periods.

The lake is central to the agrarian life of Cumbum and surrounding villages, supporting irrigation and drinking water supply. It is a local landmark and recreational space, valued for its heritage engineering and association with Vijayanagara-era water management traditions.
