The Narmada river is the 5th longest river in Indian subcontinent. It is also called as the Rewa. Narmada means "the Giver of pleasure" It rises from Amarkantak Plateau and drains into Arabian sea. It flows through the states of Madhya Pradesh and Maharashtra. Its approximate length is 1312 km. It contributes to Madhya Pradesh in many ways that's why it is called as "Life Line of Madhya Pradesh". Narmada's left tributaries include Dudhi River, Tawa River, Ganjal River, Burhner River, Banjar River, Sher River, Shakkar River, Chhota Tawa River, Kaveri River, Kundi River and Goi River, while right tributaries include Man River, Uri River, Hatni River, Orsang River, Hiran River, Tendoni River, Choral River and Kolar River.
Narmada believed as a holy river. It is believed that one who bathe in Narmada cleanses sins committed throughout his life. That's why people have polluted the river by bathing in it. Likewise other six rivers including Ganges, Yamuna, Godavari, Sarasvati, Sindhu and Kaveri are also considered the same way.
