Pallivasal project is the first hydro-electric project in Kerala was established at Pallivasal during the reign of Maharajah Sree Chithira Thirunal Balarama Varma. The project is on the river Mudirapuzha of Periyar basin in Idukki distric in Kerala. This Pallivasal electric project was commissioned in 1940. The Kerala electricity transmission system also emerged in 1940 with a 66 kV line from Pallivasal to Thiruvananthapuram. Eight substations were commissioned in 1940.

Papanasam Hydroelectric Power Plant has a design capacity of 28 megawatts. It has four Francis turbine-generators. The first unit was commissioned in 1944 and the last in 1951. It is on Thambirabarani river.

The Papanasam dam also known as Karaiyar Dam is located 49 kilometres (30 mi) away from Tirunelveli in Tamil Nadu. The dam is used to irrigate 86,107 acres (34,846 ha) of paddy fields in Tirunelveli and Tuticorin districts.

The Matatila Dam, built in 1958 on Betwa river is in district Lalitpur, Uttar Pradesh. It is situated 93 km away from Deogarh and this dam is 35 m high. The catchment area is around 20 km2 with a maximum storage capacity of 1132 million cubic metres.

Ban Sagar Dam is a multipurpose river Valley Project on Sone River situated in the Ganges Basin in Madhya Pradesh.It is utilised for both irrigation and 435 MW of hydroelectric power generation.

The Mettur Dam is one of the largest dams in India and also the largest in Tamil Nadu, located across the river Cauvery. It was built in 1934, it took 9 years to complete. The total length of the dam is 1,700 metres (5,600 ft). Its maximum height and width are 214 and 171 feet, respectively. It provides irrigation and drinking water facilities for more than 12 districts of Tamilnadu.

The Mettur Dam has received public attention since the latter half of the 20th century, and especially in the mid-1990s, due to the Kaveri River water dispute between the States of Tamil Nadu and Karnataka.

The Tehri Dam is the tallest dam in India. It is a multi-purpose rock and earth-fill embankment dam on the Bhagirathi River near Tehri in Uttarakhand. The Tehri Dam withholds a reservoir for irrigation, municipal water supply and the generation of 1,000 megawatts of hydroelectricity.

Tehri Dam is a 260.5 m (855 ft) high rock and earth-fill embankment dam. Its length is 575 m (1,886 ft), crest width 20 m (66 ft), and base width 1,128 m (3,701 ft).

The Tehri Dam has been the object of protests by environmental organizations and local people of the region. Virendra Dutt Saklani, lawyer and founder of the Anti-Tehri Dam Struggle Committee, was quick to point out the consequences associated to the large project.

Farakka Barrage Project with headquarters at Farakka in Murshidabad district of West Bengal is a subordinate office under the Union Ministry of Water Resources, River Development & Ganga Rejuvenation. The Farakka Barrage Project Authority was set up in 1961 with the mandate to execute and thereafter operate and maintain the Farakka Barrage Project Complex comprising of Farakka Barrage, Jangipur Barrage, Feeder Canal, Navigation Lock and associated structures. The Barrage comprises of 112 nos. of Gates (108 Nos. main Gates and 4 Nos. Fish Lock Gates) and 11 Nos. Head Regulator Gates for diversion of approximately 40,000 cusec (1035 cumec) of discharge into the Feeder Canal. The project construction commenced in 1961 and the project was commissioned and dedicated to the Nation in May 1975.

Main objective of the Farakka Barrage Project complex is to divert adequate quantity of Ganga waters to Bhagirathi-Hoogly river system through 38.38 km long feeder canal for preservation and maintenance of Kolkata Port by improving the regime and navigability of the Bhagirathi-Hoogly river system. The increased upland supply from Ganga at Farakka into Bhagirathi reduces salinity and ensures sweet water supply to Kolkata and surrounding areas. The rail-cum-road bridge built across the river Ganga at Farakka establishes direct road and rail communication link to the North-Eastern Region with rest of the country. The Hoogly-Bhagirathi river system, the Feeder Canal and the Navigation Lock at Farakka form part of the Haldia-Allahabad Inland Waterway (National Waterway No:1). The Feeder Canal also supplies water to 2100 MW Farakka Super Thermal Power Project (FSTPP) of NTPC Ltd. at Farakka.

Loktak Lake is the largest freshwater lake in North East India and is famous for the phumdis (heterogeneous mass of vegetation, soil and organic matter at various stages of decomposition) floating over it. The lake is located at Moirang in Manipur state, India. The etymology of Loktak is Lok = "stream" and tak = "the end".

Loktak Day is observed every year on the 15th of October at the periphery of the Loktak lake.

It serves as a source of water for hydropower generation, irrigation and drinking water supply. The lake is also a source of livelihood for the rural fishermen who live in the surrounding areas and on phumdis, also known as "phumshongs".
