Ravish Tiwari While the severe rainfall deficit in the upper Yamuna basin last year has been handsomely compensated this year, it has come with a rider of its own. The normal rainfall in the basin has brought with it flood threats ahead of the Commonwealth Games in the capital and has served as a reminder for the government to harness the rainwater flowing down the Yamuna. The lack of water storage projects in the upper Yamuna basin has long been a concern. The three planned water storage projects, with a total capacity of over 2 billion cubic meters (bcm) storage upstream, are still struggling to get off the ground in spite of the 90 per cent Central funding promised by the government in 2008.
