Union minister Nitin Gadkari has said the government is working on project to divert water from three rivers flowing into Pakistan from India in order to improve availability of water in the Yamuna. He said both the countries hold the right to use water flowing in three rivers each under the Indus Waters Treaty signed in 1960. But India has not utilised river waters it is permitted to use under the agreement, he said. Once the water is diverted, Yamuna river will have more water, Gadkari added.
