The government has decided to declare the Ganga a national river, following campaigns from several quarters to preserve its cultural and religious significance. A High Powered Ganga River Basin Authority, to be chaired by the prime minister, will be set up as an empowered planning, implementing and monitoring authority for the river. The Ministry of Environment and Forests, or MOEF, has decided to conduct a basin-wide pilot study of the ecological impact of hydel projects coming up on the Ganga.

The events were set into motion by a letter written by Congress chairperson Sonia Gandhi to Union water resources minister Saifuddin Soz in mid-August. The letter was forwarded to MOEF, which called a n inter-ministerial meeting in September. The decision to carry out the pilot study was taken at the meeting attended by representatives of water resources and power ministries, Central Water Commission, Central Electricity Authority and the National Thermal Power Corporation (ntpc).

The study will be conducted from Dharasu to Gangotri lying in the stretch of the Ganga’s tributary Bhagirathi in Uttarakhand. It will help in the planning of hydropower projects and maintaining adequate water flow in the river for its ecological health. IIT Roorkee and G B Pant Institute of Himalayan Environment and Development, Almora, have bee asked to submit proposals for conducting the study.

Projects coming up on the Ganga’s tributaries, the Bhagirathi and the Alaknanda, are planned in such a way that the tunnel of one ends only a small distance before the reservoir of the next one. This will leave no patch of the river to flow freely (see ‘Myth of Power’, Down To Earth, September 1-15, 2008).

Another committee was set up in July by ntpc on the power ministry’s directions to look into the minimum flow required in the Bhagirathi to maintain its ecological health—this is called environmental flow—and to find out the populations of fish and other species around the Loharinag Pala dam and its impact on them. Two projects upstream of Uttarkashi, Bhairon Ghati and Pala Maneri, were stalled after G D Agarwal, former member secretary of the Central Pollution Control Board, went on hunger strike in June. But work on ntpc’s Loharinag Pala project is under way.

The study on environmental flow , done by the National Institute of Hydrology (nih), Roorkee on behalf of ntpc, concluded that a flow of at least 16 cubic metre per second (cumecs) needed to be maintained at the dam site.

“But ntpc’s proposal said only three cumecs will be maintained. We have asked the nih team for clarifications. Only then the final decision (on letting the dam function) will be take,”

said Rajendra Singh, member of the committee. moef recommends a minimum flow of a little less that one cumec, while the Bhagirathi requires 13 cumecs of flow throughout the year to maintain its Class A status. The International Water Management Institute defines a Class A river as one whose water needs little treatment for drinking.

New study, just hogwash?

Environmentalists have criticized the pilot study on grounds that moef will only be repeating what the earlier committee has undertaken. Vimal Bhai head of Matu People’s Organization, an environmental group active in Uttarakhand, said,

“The new study is hogwash. More than a year ago, the National Environment Appellate Authority had told moef to set up a monitoring committee to oversee Loharinag Pala project. The ministry has not done so. When asked it cited lack of staff as the reason. When it could not monitor one project, how can we trust it on this study, which is for the entire stretch? And the construction is not even being stopped. What will they study once the dams are already there.”

An MOEF official, who attended the inter-ministerial meeting, told Down To Earth, that the Uttarakhand government was “playing hide and seek and might restart the projects once the elections are over”.
