Osman Sagar (Telugu: ఒస్మాన్ సాగర్, Urdu: عثمان ساگر) popularly known as Gandipet, is an artificial lake in the Indian city of Hyderabad. The lake is around 46 km², and the reservoir is around 29 km².

Osman sagar was created by damming the Musi River in 1920, for providing drinking water source for Hyderabad, and also saving the city from floods, on the lines of which Hyderabad suffered in 1908. It was during the reign of The Last Nizam of Hyderabad, Osman Ali Khan, hence the name.

A princely guest house called Sagar Mahal, overlooking the lake, now a heritage building, was built as a summer resort of the last Nizam. It is located on the banks and has the best view of the lake. Andhra Pradesh Tourism Department [1], currently, runs the place as a resort. The breeze of the lake is very pleasant, and has been popular with the locals since The Nizam's time.

It is a popular tourist destination, especially after the rainy season when the reservoir is full, and its parks, resorts, amusement park are a major attraction. This lake had served drinking water for Hyderabad city but due to increase in population it is not sufficient for water supply to Hyderabad city and so now it is used for public recreation.

The CBI arrested V. D. Rajagopal and Y. Srilakshmi, as third and fourth accused respectively in the investigation into illegal mining by Obulapuram Mining Company. The permission for mining in Anantapur was for captive mining, i.e. the ore mined in that region is to be used in the local steel plant and not to be exported. Srilakshmi is accused of dropping the term "captive mining" in the final order approving a mining license to Obulapuram. Srilakshmi suggested that this was done at the insistence of the former Minister of Mines and current Andhra Pradesh Home minister Sabitha Indra Reddy . However the CBI defended the Home minister, who is a senior local politician of the ruling Congress party .
