Maneri Dam

The Maneri Dam is a concrete gravity dam on the Bhagirathi River located at Maneri, 8.5 kilometres (5.3 mi) east of Uttarkashi in Uttarkashi district, Uttarakhand, India. The primary purpose of the dam is to divert water into a tunnel which feeds the 90 megawatts (120,000 hp) run-of-the-river Tiloth Power Plant.

The power station is stage one of the Maneri Bhali Hydroelectric Project which was planned in the 1960s. It was completed and commissioned in 1984. Dharasu Power Station, the second stage, was halted in 1990 due to funding issues and was not restarted until 2002.[1] It was eventually completed and commissioned by 2008.[2]

Design and operation

The Maneri Dam is a 39 m (128 ft) tall and 127 m (417 ft) wide gravity dam with a structural volume of 13,700 m3 (17,919 cu yd). It's spillway is located on its crest and is controlled by four tainter gates. In addition to discharge tunnel, the spillway has a maximum discharge capacity of 5,000 m3/s (176,573 cu ft/s). The dam's reservoir has a 600,000 m3 (486 acre⋅ft) capacity, of which 510,000 m3 (413 acre⋅ft) is active (or "useful") capacity.[3] Water supplied to the power station is first diverted from the Bhagirathi River by the dam into a 8.6 km (5.3 mi) long tunnel directly behind the dam. The difference in elevation between the barrage and the power station affords a design hydraulic head of 147.5 m (484 ft) and gross head of 180 m (590 ft). Near the Tiloth Power Plant, the tunnel splits into three penstocks to power each of the three 30 MW Francis turbine-generators before being discharged back into the river. The design discharge of the power station is 71.4 m3/s (2,521 cu ft/s).[4]

Bhagirathi River

The Bhāgīrathī (Pron:/ˌbʌgɪˈɹɑːθɪ/) is a turbulent Himalayan river in the Indian state of Uttarakhand, and one of the two headstreams (or source) of the Ganges, the major river of Northern India and considered holy in Hinduism. In Hindu faith and culture, the Bhagirathi is considered the source stream of the Ganges. However, in hydrology, the other headstream, Alaknanda, is considered the source stream on account of its great length and discharge.

Maneri Bhali Hydroelectric Project

The Maneri Bhali Hydroelectric Project in Uttarakhand, India refers to one of its two stages:

Maneri Dam – Stage I (1984), 90 MW

Bhali Dam – Stage II (2008), 304 MW


Uttarkashi, meaning Kashi of the north, is a town in Uttarakhand, India. It is the district headquarters of Uttarkashi district. Uttarkashi is situated on the banks of river Bhagirathi at an altitude of 1158 m above sea level. Uttarkashi is generally known as a holy town close to Rishikesh. It is located in the state of Uttarakhand in India. Uttarkashi is home to a number of ashrams and temples and also to the Nehru Institute of Mountaineering. The name of the town reflects its similarity to and location (as north of) the city of Kashi (Varanasi). Similar to Varanasi, town of Uttarkashi is situated on the Ganges, lies next to a hill named Varunavat, on confluence of two rivers Varuna and Asi, has a ghat called Manikarnika Ghat and has a temple dedicated to Shiva similar to (Kashi Vishwanath Temple) in Varanasi , in the center of the town.
