Tenders of one and four package of Dummugudem-Nagarjunasagar Project tail pond link canal, the first of its kind in the country in river linkage of Godavari and Krishna rivers, would be put online for e-procurement on February 27. The first package is an approach canal from zero to 6.5 km and water would be drawn from Godavari at the time of floods and it would be taken to the tail pond of Nagarjunasagar reservoir. Water would be drawn when the river crosses 52.5 feet and would be diverted through 6.5 km length approach canal on gravity. There is no need for lifting it to the point. The contracts would be called on engineering-procurement-construction (EPC) system. Though the engineers of the project evolved a plan for the packages on behalf of the government the companies which obtained the tenders have to submit fresh engineering, procurement and construction plans for the packages of the project. As a result, the cost may be reduced or increased as per the approved plan. The fourth package is for constructing a pump house for 20,000 cusecs and digging a canal from 38.5 km to 48 km. The project officials planned to call the tenders on February 21 but it was postponed to February 27 to finalise the cost of the two packages. Officials are tight-lipped about the cost of the project, but sources said that the two packages would cost Rs 550 crore. The total cost of the project is estimated to be Rs 8,930 crore and the project work would be divided into more than 18 packages. Water can be drawn only during floods.

The multi-crore Polavaram project in Andhra Pradesh is currently embroiled in legal issues. But now, the project is being contested on technical issues as well. A study carried out by the

This paper shows that, while total water available in the Lower Krishna Basin is decreasing, changes in the waterscape of the basin are being shaped, to a large extent, by local users. This study underlines that it is not only the availability of the physical resource that is crucial in explaining the evolution of water use but, as water has become a disputed and highly politicized object, waterscapes are also strongly shaped by the social and political conditions of a region (a state for example), the boundaries of which often exceed the area where water is effectively used.

This report examines aspects of hydrological and environmental feasibility of interbasin water transfers in India and forms part of the larger research project which deals with multiple aspects of the National River Linking Project. The study uses the water transfer links in and out of the Krishna River Basin as examples.

An agitational approach to river disputes only prolongs them

This paper summarizes research on the Krishna River Basin in southern India, including physical and agricultural geography, remote sensing, hydrology, water management, and environmental
issues. Discharge from the Krishna into the ocean decreased rapidly from 1960-2003 due to irrigation expansion. Annual runoff to the ocean fell from a pre-irrigation average of 56 cubic
kilometers (km3)(1901-1960) to 13 km3 (1994-2003), despite no significant change in rainfall. By the late 1990s, the cumulative reservoir capacity in the basin approximated the annual runoff

IT is the time of the day when all able-bodied men in any village should be working in the fields. However, at the Biligi rehabilitation centre in Karnataka's Bagalkot district, a group of unemployed men are seated behind an electronic keyboard on the sun-baked floor, practising music for a stage play.

Interstate Disputes over Krishna Waters

india is facing the worst kind of floods in some of its most dammed states. Maharashtra, Madhya Pradesh, Gujarat and Andhra Pradesh top the list of states with the maximum number of dams.
