Gandipet is also called as Osmansagar Lake, located on the outskirts of Hyderabad and is about 20 kilometres away from the centre of the city. It is built as a Dam over Musi River on west of Hyderabad by mainly concentrating for the water supply for the Hyderabad people and also saving people from floods.
Mir Osman Ali Khan the seventh Nizam has constructed the dam in the year 1920 because the great musi floods had devastated the people of Hyderabad in his reign itself.This lake is spread across 46 square kilometres and has become the main drinking source water for the people of Hyderabad and Secunderabad.
This has also become the one of major tourist places of Hyderabad because of its lush green gardens and its naturalities. Whether it may be any season people visit here and have their stay for a whole day just by enjoying the nature by having some eatables which are available on the banks of the lake. Boating and swimming facilities are also provided in this site. This place has got a great morning view with water that shimmers golden colour in the morning sun and the cool breezes with its extraordinary locations with the big trees near and around the lake which cannot be viewed in metropolitan cities like Hyderabad. The Sagar Mahal over here is a heritage building that was built by the Nizam as a resort in his period and is now maintained by the AP Tourism which has about ten double rooms used by the visitors as guest houses.
