About Uttarakhand Rivers
The water quality of Uttarakhand‘s rivers is basically good, especially in the upper reaches. Downstream of some large settlements and in the lower reaches in the Himalayan foot hills the water quality suffers due to the release of untreated sewage and industrial effluents. But the state‘s ambitious program to build 450 hydro power projects threatens the survival of the river ecosystems and the lives and livelihoods of people who live in these river valleys.
- Yamuna [Tons, Rupin, Aglar, Asan, Assi Ganga, Kamal Ganga]. Rivers Yamuna, Tons, and Rupin are threatened by a series of dams and barrages. The lower middle stretch of the Tons is already RED due to two large dams. The release of untreated industrial waste waters threatens the Asan.
- Bhagirathi [Jadh Ganga, Assi Ganga, Jalkur and Bhilangana]. The free flow of R. Bhagirathi is destroyed by a series of dams and barrages over a 100 km stretch. R. Bhilangana has two medium size dams on it and the lower reach is submerged by the Tehri dam.Jadh Ganga and Assi Ganga are threatened by proposed dams and barrages.
- Alaknanda [Dhauliganga , Nandakini, Pindar, Mandakini]. The free flow of R. Alaknanda is affected below the Vishnuprayag barrage (25 km) and u/s of the Srinagar dam (25 km). Under construction HEPs threaten about 50% of the Dhauliganga length. The Singoli-Bhatwari HEP affects 17 km length of the Mandakini. A few dams and barrages are to be built on the Pindar and the Nandakini.
- Ganga [ Nayar, Song, Suswa]. R, Ganga‘s free flow is threatened by the Kotli-Bhel II project and the river is polluted d/s of Rishikesh. Nayar is drying up and Suswa and Song are threatened by pollution problems.
- Ramganga [Gagas, Kosi]. R. Ramganga is a healthy river above the Kalagarh dam just 3 km u/s from where it exits Uttarakhand. Gagas and Kosi rivers are drying due to reduced base flows and heavy extraction.
- Kaliganga [Dhauliganga (E), Goriganga, Ramganga (E), Saryu, Ladhiya]. R. Dhauliganga (E) and Goriganga will mostly dry up if all the proposed HEPs on them are built. The water quality of the Saryu is already threatened.
