Dimna Lake

Dimna Lake is an artificial reservoir located at the foothills of the Dalma Hills near Dimna village, about 13 km from Jamshedpur in East Singhbhum district, Jharkhand. Constructed in 1944 by Tata Steel to supply water to Jamshedpur and its industrial operations, it is surrounded by forested hills and serves as a popular picnic and day-trip destination offering scenic views, boating facilities and proximity to Dalma Wildlife Sanctuary.

Visitors can expect a large reservoir surrounded by the forested slopes of the Dalma Hills with calm waters and open shoreline areas. The site offers viewpoints over the lake and hills, boating on the lake, and open spaces used for picnics and sightseeing. Facilities include parking and small food stalls. The area is natural and relatively undeveloped, with forested surroundings and views of the Dalma range.

Dimna Lake was constructed in 1944 by Tata Steel as a reservoir to meet the drinking water and industrial water needs of Jamshedpur. The dam across a small stream at the foothills of Dalma Hills created the reservoir which continues to supply water to the city.
