It was built in 1989. on the seasonal Sahibi river which is 120 km long and flows from Aravalli hills in Rajasthan to South Haryana and Delhi. After Sahibi river caused floods in 1977, then Prime Minister Morarji Desai mandated a flood control and water utilizationmaster plan for the Sahibi river basin, consequently under which construction on Masani barrage commenced in February 1979 and completed in 1989.
Location and transport
Masani barrage is also used as the bridge on National highway NH 919 which merges with national highway NH 48 at this barrage. Union govt announced the plan to four-lane the Masani barrage road.
Barrage
Technical details
It lies in the Indian seismic zone IV. It has 18 gates/bays to release water. 18 km barrage wall built at the cost of INR 50 crore has 400 to 500 acre resorvior to hold water.
Irrigation and flood control
Barrage was built to provide irrigation facilities to 50,000 acres in Haryana, and flood protection to 1.60 lakh acres in Haryana and 40,000 acres in Delhi.
Since Masani falls on the Golden Triangle tourist circuit, a large number of international and domestic tourist pass through viathe national highway connecting Delhi-Agra to Jaipur & Bikaner-Jaisalmer, this is continuously being improved as a major tourist stop. Lakes here have boating, nature's trail, herbal and eco park, resthouse and lodging, food court and restroom facilities. A zoo is also under development in 2018-19.
Golden Jubli lakes and nature park
This is located immediately upstream of the barrage. Two lakes, at Masani barrage flood gates and next to Nikhri village, within immediate upstream catchment of the barrage were dugout, rejuvenated and made perennial using the water from the Lal Bahadur Shastri channel of Jawahar Lal Nehru Canal from Western Yamuna Canal. Boating facilities have been made available at these lakes. Of the planned 18 km nature's trail along its bank under development, 6 km have been readied already by August 2018. The lakes are an important feeding and breeding ground for large number of migratory birds who arrive here every year.
1970s-80s plans to recharge the subsoil water vanished with the continual reduction in rainfall and construction of several dams over the Sahibi river in Rajasthan, resulting in basin of the Masani Barrage remaining dry since the late 1980s. Entire 100 km stretch of Sahibi river and its streams in Haryana are ecologically dead. Gurugram also dumps polluted discharge in the riverbed of Sahibi.
Restoration
is coordinating with Government of Rajasthan to ensure water reaches usually-dry masani barrage and dying seasonal Sahibi river. Another govt. project is being implemented to direct the extra water of Yamuna river during monsoon to Masani barrage through Jawahar Lal Nehru Canal and Western Yamuna Canal. In 2016, govt decided to disallow farming on 700 acre land around Masani barrage floodplain of Sahibi river, annually leased to the farmers since 1979, so that the land can be returned to the forest department. During 3 months monsoon season surplus water is available from Yamuna which is brought here to create a reservoir of 15 to 20 feet high water, during dry reason the treated seawage water from Rewari and Dharuhera will be brought from this barrage. Upstream large patches of isolated forests and dried lake beds are adjacent to the course of seasonal Sahibi near the villages of Bolni, Bidawas, Jhabuwa, Jat Bhagola, Ajarka, Manethi, Karni Kot and Neemrana, which could be made perennial with excess water thus creating an interconnected-wetlands based eco-corridor in the Delhi Supergroup of Aravalli range from Sariska Tiger Reserve to various nature and national parks of Delhi Ridge up to the national capital of New Delhi.
