The Krishna River is the fourth-largest river in terms of water inflows and river basin area in India, after the Ganges, Godavari and Brahmaputra. The river, also called Krishnaveni, is almost 1,288 kilometres (800 mi) long. It is a major source of irrigation in the Indian states of Maharashtra, Karnataka, Telangana and Andhra Pradesh.
The Godavari is India's second longest river after the Ganga and third largest in India, drains about 10% of India's total geographical area. Its source is in Trimbakeshwar, Nashik, Maharashtra. It flows east for 1,465 kilometres (910 mi), draining the states of Maharashtra (48.6%), Telangana (18.8%), Andhra Pradesh (4.5%), Chhattisgarh (10.9%) and Odisha (5.7%).

The Sardar Sarovar Dam is a concrete gravity dam built on the Narmada river in Navagam near Kevadiya, Narmada District, Gujarat in India. Indian states Gujarat, Madhya Pradesh, Maharashtra and Rajasthan receive water and electricity supply from the dam. The foundation stone of the project was laid out by Prime Minister Jawaharlal Nehru on 5 April 1961. The project took form in 1979 as part of a development scheme funded by the World Bank through their International Bank for Reconstruction and Development, to increase irrigation and produce hydroelectricity, using a loan of US$200 million. The construction for dam begun in 1987, but the project was stalled by the Supreme Court of India in 1995 in the backdrop of Narmada Bachao Andolan over concerns of displacement of people. In 2000–01 the project was revived but with a lower height of 111 metres under directions from SC, which was later increased in 2006 to 123 metres and 139 metres in 2017. The dam was inaugurated in 2017 by Prime minister Narendra Modi. The water level in the Sardar Sarovar Dam at Kevadia in Narmada district reached its highest capacity at 138.7 metres on 15 September 2019.

Periyar, IPA: [peɾijɐːr], is the longest river and the river with the largest discharge potential in the Indian state of Kerala. It is one of the few perennial rivers in the region and provides drinking water for several major towns. The Periyar is of utmost significance to the economy of Kerala. It generates a significant proportion of Kerala's electrical power via the Idukki Dam and flows along a region of industrial and commercial activity. The river also provides water for irrigation and domestic use throughout its course besides supporting a rich fishery. Due to these reasons, the river has been named the "Lifeline of Kerala". Kochi city, in the vicinity of the river mouth draws its water supply from Aluva, an upstream site sufficiently free of seawater intrusion. Twenty five percent of Kerala's industries are along the banks of river Periyar. These are mostly crowded within a stretch of 5 kilometres (3 mi) in the Eloor-Edayar region (Udhyogamandal), about 10 kilometres (6 mi) north of Kochi harbor.
The Subarnarekha River flows through the Indian states of Jharkhand, West Bengal and Odisha.

Mullaperiyar DamIPA: [mulːɐpːeɾijɐːr], is a masonry gravity dam on the Periyar River in the Indian state of Kerala It is located 881 m (2,890 ft) above mean sea level, on the Cardamom Hills of the Western Ghats in Thekkady, Idukki District of Kerala, India. It was constructed between 1887 and 1895 by John Pennycuick and also reached in an agreement to divert water eastwards to the Madras Presidency area. It has a height of 53.6 m (176 ft) from the foundation, and a length of 365.7 m (1,200 ft). The Periyar National Park in Thekkady is located around the dam's reservoir. The dam is built at the confluence of Mullayar and Periyar rivers. The dam is located in Kerala on the river Periyar, but is operated and maintained by the neighbouring state of Tamil Nadu. Although the Periyar River has a total catchment area of 5398 km2 with 114 km2 downstream from the dam in Tamil Nadu, the catchment area of the Mullaperiyar Dam itself lies entirely in Kerala and thus not an inter-State river. On 21 November 2014, the water level hit 142 feet for first time in 35 years. The reservoir again hit the maximum limit of 142 feet on 15 August 2018, following incessant rains in the state of Kerala. In a UN report published in 2021, the dam was identified as one among the world's big dams which needs to be decommissioned for being 'situated in a seismically active area with significant structural flaws and poses risk to 3.5 million people if the 100+ years old dam were to fail'.
The ponmudi dam is a concrete gravity dam built across the Panniyar river which is a tributary of Periyar River at Konnathadi panchayath of Konnathadi village in Idukki district of Kerala, India.
