History
Osman Sagar was created by damming the Musi River in 1920, to provide an additional source of drinking water for Hyderabad and to protect the city after the Great Musi Flood of 1908. It was constructed during the reign of the last Nizam of Hyderabad State, Osman Ali Khan, hence the name.
A princely guest house called Sagar Mahal, overlooking the lake and now a heritage building, was built as a summer resort of the last Nizam. Its location on the banks of the lake offers wonderful views. Telangana Tourism Department [http://www.aptourism.in/hyderabad.html] operates a resort in the building. The breeze of the lake is very pleasant and has been popular with the locals since Nizam's time. When the Nizam consulted Sri Sir M.Visheswaraya regarding the twin problems of heavy floods in monsoon and acute shortage of water during summer, the latter designed a plan for construction of a Dam which needed high engineering skills in those days. This simple yet elegant solution solved both problems for Hyderabad.
Tourist spot
It is a popular tourist destination, especially in monsoon season when the reservoir is full. Its parks, resorts, and amusement park are a major attraction. This lake had served drinking water to Hyderabad city but, due to increase in population, is not sufficient to meet the city's water supply demand.{{cite web |last1=sharma |first1=amit |title=Gandipet lake timings, gandipet park, osman sagar, gandipet cheruvu |url=https://www.wiki.meramaal.com/2018/10/05/gandipet-lake-hyderabad-osman-sagar/ |website=meramaal.com|date=5 October 2018 }}
Himayat Ali Mirza, great-grandson of Nizam VII has recently joined the “save Osmansagar and Himayatsagar” campaign for saving the twin reservoirs and has also urged the of Telangana CM to scrap the orders of GO 111.{{Cite web |author=Syed Akbar|date=Mar 28, 2022 |title=nizam: Nizam's Kin Joinsfight To Save Lakes {{!}} Hyderabad News - Times of India |url=https://timesofindia.indiatimes.com/city/hyderabad/nizams-kin-joinsfight-to-save-lakes/articleshow/90482234.cms |access-date=2022-04-05 |website=The Times of India |language=en}}{{Cite news |date=March 28, 2000 |title=nizam: Nizam's Kin Joinsfight To Save Lakes {{!}} Hyderabad Information |work=The Times of Truth |url=https://www.thetimesoftruth.com/nizam-nizams-kin-joinsfight-to-save-lakes-hyderabad-information/}}{{dead link|date=March 2025|bot=medic}}{{cbignore|bot=medic}}{{Cite web |title=Nizam's relatives have joined the struggle to save Hyderabad's lakes. |url=https://thetimesbureau.com/nizams-relatives-have-joined-the-struggle-to-save-hyderabads-lakes-202203/ |access-date=2022-06-17 |website=thetimesbureau.com}}
Himayat said that now that the government had withdrawn the GO 111, the floods might affect various parts of the city. Scrapping of GO 111 has led to increasing the construction and concretisation activities near the lakes, ultimately resulting in consequent flooding.{{Cite web |author=Syed Akbar|date=May 9, 2022 |title=old city: 'repeal Of Go 111 To Spell Old City's Flood Threat' {{!}} Hyderabad News - Times of India |url=https://timesofindia.indiatimes.com/city/hyderabad/repeal-of-go-111-to-spell-old-citys-flood-threat/articleshow/91425696.cms |access-date=2022-06-15 |website=The Times of India |language=en}}{{Cite web |date=2022-04-23 |title=Explained: What is GO 111, the order to protect Hyderabad's Osman Sagar and Himayat Sagar, that has now been lifted |url=https://indianexpress.com/article/explained/go-111-order-to-protect-hyderabad-osman-sagar-himayat-sagar-lifted-7882177/ |access-date=2022-06-17 |website=The Indian Express |language=en}}
