The government does not have any record of "exact quantity of water" flowing from different rivers from India to Pakistan.
The revelation came through a response of Ministry of Water Resources to an RTI query, which said the "exact quantum" of waters flowing down to the neighbouring country was not known.
"River Ravi flows from Jammu and Kashmir into Punjab before entering Pakistan. The Beas confluences with the Sutlej at Harike and the combined river Sutlej enters Pakistan. Some tributaries or nallahs of these rivers cross over directly from India to Pakistan. The exact quantum of waters flowing down to Pakistan is not available," the Ministry said.
According to the Indus Waters Treaty, 1960, between New Delhi and Islamabad, waters from eastern rivers -- Sutlej, Beas and Ravi -- stand allocated to India and those from western rivers namely Indus, Jhelum and Chenab largely to Pakistan.
Exercising his Right to Information, Vivek Garg, an advocate had filed an application to the Water Resources Ministry seeking details on quantity of water from different eastern and western rivers flowing to Pakistan.
He also sought the details of efforts made by the Government of India to stop this water and expenditure incurred on it.
India is under obligation to let flow all the waters of Jhelum, Indus and Chenab and not permit any interference with these waters except for certain specified uses, in accordance with the Treaty, the reply said.
“The Ravi, Beas and Sutlej waters are allocated among various states. Thein Dam, Pong Dam, Nangpal Dam and Headworks at Ropar, Harike and Ferozepur serve to divert these waters into various canal systems of Punjab, Haryana and Rajasthan.
“However, water being a state subject, the information in respect of use of water from these projects on the concerned rivers along with their financial details can be requested or sought from the state government concerned,” the Ministry said.
The average annual flow of the rivers of Indus System is 207 billion cubic metre, including 166 bcm of western rivers.
“Millions of cubic metre water is illegally flowing from our land to Pakistan every year. This water can easily be utilised by thousands of farmers in Punjab and Haryana. These two states administrations are doing nothing to stop this precious water and letting their peasants suffer,” Garg claimed.
