Bhagirathi Lake

 Bhagirathi Lake

A temporary lake formed on the Bhagirathi River in Harshil, Uttarakhand, following flash floods triggered by heavy rainfall on August 5, 2025, in the Dharali village area. The lake was created when a local stream named Telgad, near an Army camp in Harshil, became active and carried a large volume of debris and water into the Bhagirathi River. This debris accumulated at the confluence point, forming a large fan-shaped deposit of sediments, known as an alluvial fan, which obstructed the river’s original channel. The resulting lake spanned approximately 1,500 meters in length and had an estimated depth of 12 to 15 feet. Some reports noted the lake's length as between 800 to 900 meters, with a depth of 15 to 20 feet and an average width of 100 meters

The blockage significantly altered the river’s topography, eroding a sand dune on the right bank while depositing fresh sediment on the left bank, which exposed parts of Harshil town. The lake submerged about 200 meters of the Gangotri National Highway and a helipad, posing a serious threat to downstream areas. Due to the saturated and weak nature of the alluvial fan, heavy machinery such as JCBs could not be deployed, limiting the response to manual methods. To prevent sudden downstream flooding, a controlled drainage plan was implemented, involving the creation of small diversion channels, 9 to 12 inches deep, opened in three or four stages. The State Disaster Response Force (SDRF) and the Irrigation Department of Uttarakhand carried out the work, successfully facilitating gradual water drainage over two days. The blockage was partially removed, and the river’s flow was restored through these phased efforts.
