Dams might have Negative Influence on River Ganges, says Water Resource Ministry of India

The water resource ministry has opposed the hydroelectric projects on the Alaknanda, Bhagirathi and Mandakini River hence contradicting the permission given by environment and power ministries for setting up of dams.

After the Kedarnath incident of 2013, when around 100,000 pilgrims remain trapped in the Uttarakhand valley after serious landslides and bad monsoon, the Supreme Court had put a hold on all the 70 proposed hydroelectric projects on the Alaknanda-Bhagirathi river basin. On May 10, SS Patwalia, additional solicitor general brought to notice that the environment and power ministry has approved the construction of five of the six projects, namely— Lata-Tapovan (171 MW), Jhelum Tamak (108 MW), Kotlibhel 1-A (195MW), Alaknanda (300 MW), Khironi Ganga (4 MW) and Bhyunder Ganga (24 MW).

The water resource ministry headed by Uma Bharati informed the Supreme Court that any further hydroelectric projects on Alaknanda, Mandakini and Bhagirathi rivers can be dangerous for Ganga.

The ministry argued that the permission was given before the unfortunate Kedarnath tragedy of 2013 but now there is need for a comprehensive hydrological and hydro-geological study to know how dams can affect the flow of rivers.

“All these new projects are coming up close to the existing projects, many of which are in ecologically sensitive areas hindering the source of fresh water resource. Hence, any further project will have substantial impact on ecological footprint of the area,” the ministry said.

According to the ministry, the permitted projects are around regions which are geologically weak and seismically sensitive. So, there is a need to review these projects. The ministry said that Ganga could remain pure and pristine only if Alaknanda, Mandakini and Bhagirathi rivers are allowed to flow freely invoking the ‘Aviral Dhara’ of the Indian government which aims for a clean and continuous flow of the river Ganga.

1. Therer are other new sustainable innovations to think about having solutions without building dams, look at this link at their brochure http://issuu.com/oryonwatermill/docs/brochure_oryon_watermill_engels_low/1,  
   Deepwater  Energy  developed  the  Oryon  Watermill,  a  simple,  but  highly
   effective  hydropower  station  which  will,  with  low  rpm,  generate  a  profitable
   capacity  of  sustainable  energy  in  slow  flowing  rivers  with  low  decline  with
   currents as of 1 m/sec.

2. Dams with in say 50 to 70 km of the start may not affect the river systems if minimum flows are ensured with bye pass arrangements for perpetual flows. However, creation of Lakes in proximity to Rivers to store excess flows and rain/ storm waters may enhance the strength of the river system. For each River System, the design solution can be developed to check Feasibility of Dams, Diversion  and infusion of flows into Lakes/ Reservoirs and even pumping of part of flows upstream to maintain minimum flows in certain sections before big tributary joins the main river.
