Once upon a time, Hyderabad was known as City of Lakes. Some of these lakes are natural and various are man made bodies per various sources only a few decades back, Hyderabad had a large number of water bodies such as lakes, reservoirs, rivers, streams, aquaculture ponds, tanks etc. (as per some sources between 3000 and 7000 including natural and manmade bodies. Locally known as cheruvu, kunta, tanks ). Most of these lakes have totally disappeared and the surface area of most of the surviving lakes have shrunken and turned to tiny ponds and cesspool.Some of the lakes which have totally disappeared are Tigal Kunta, Somajiguda Tank, Mir Jumla tank, Pahar Tigal Kunta, Kunta Bhawani Das, Nawab Saheb Kunta, Afzalsagar, Nallakunta, Masab Tank etc. Hussainsagar Lake, Kunta Mallaiyapalli have shrunk drastically. Out of thousands of water bodies those were existing in 1970s in various sizes in and around Hyderabad, today only about 70 to 500 of them have survived. Most of them have disappeared due to encroachment or have been illegally drained for real estate projects by private or government agencies. The existing lakes have been used to dump garbage and sewage water. Most of these lakes and tanks were built during the regime of Qutub Shah in 16th and 17th century and later by Nizams as a source of drinking water for the residents of Hyderabad.The area of Hussain Sagar, which is the largest lake in Hyderabad shrunk by more than 40% i.e. from 550 ha to 349 ha in just 30 years. This lake was built in 1575 AD and since 1930 is not being used as a source for drinking water.
