(a) whether it is a fact that the Government takes up issues pertaining to inter-State river water sharing and changing course of rivers in the inter-State council meeting;
(b) if so, the salient features and the guidelines for taking up issues pertaining to desilting and changing course of rivers along with their impact in the said meetings;
(c) whether the Government is aware that changing course of rivers Ganga and Sarayu on the border of Bihar and Uttar Pradesh has affected more than 25 villages in Saran district of Bihar and Balliya district of Uttar Pradesh and if so, the details thereof; and
(d) whether the Government is taking any action and holding consultations with the respective States for coordination and to ensure that the villages are not inundated by floods due to changing course of these rivers and if so, the details thereof?

Answer given by the minister

THE MINISTER OF STATE FOR WATER RESOURCES, RIVER DEVELOPMENT AND GANGA REJUVENATION & PARLIAMENTARY AFFAIRS

(SHRI ARJUN RAM MEGHWAL)

(a) & (b) As per the Presidential Order dated 28.5.1990 issued under Article 263 of the Constitution, the Inter-State Council is a recommendatory body and has been assigned the duties of (i) investigating and discussing such subjects, in which some or all of the States or the Union and one or more of the States have a common interest, as may be brought up before it; (ii) making recommendations upon any such subject and in particular recommendations for the better coordination of policy and action with respect to that subject; and (iii) deliberating upon such other matters of general interest to States as may be referred by the Chairman of the Council. Accordingly, such subjects which are referred to the Council by the State Governments are taken up for discussion in the meetings of the Council. As the Council has not been assigned the duties and responsibilities of “inquiring into and advising upon disputes which may have arisen between States” as envisaged under Article 263 (a) of the Constitution, disputes between the States are not being discussed in the meeting of the Council.

(c) Erosion and deposition are natural processes of a river, due to which morphology of a river changes with time. A Memorandum of Understanding was signed between IIT, Roorkee and Central Water Commission to carry out the morphological study of river Ganga. In the study, shifting of the Ganga river is calculated on the basis of center line of year 2010. Center line of year 2010 is perpendicularly bisected at a regular interval of 2 km. The shift of left bank, right bank and center line in left and right directions has been computed for the years 1970, 1980, 1990 and 2000 with respect to year 2010 in GIS software. The details of the Changes in the Course of Ganga River of Year 1970, 1980, 1990 and 2000 w.r.t. 2010 near Saran and Balia district are attached at Annexure-I. No study for assessment of change in course of Sarayu river is available.

(d) The subject of flood management including erosion control falls within the purview of the States. The flood management & anti-erosion schemes are planned, investigated and implemented by the State Governments with their own resources as per priority within the State. The Union Government renders technical guidance and promotional financial assistance to States.

The Government of India had launched Flood Management Programme (FMP) in XI Plan which was continued during XII Plan for providing Central Assistance to States for works related to flood control, river management, anti-erosion, drainage development, flood proofing, restoration of damaged flood management works, anti-sea erosion, catchment area treatment, etc.

For 11 Ganga basin States on issues of common interest pertaining to flood management aspects, Ganga Flood Control Commission (GFCC) holds periodic consultation with stake holder States. The issue of inundation on the border of Uttar Pradesh and Bihar on river Ganga and Sarayu was also discussed in the recently held 51st meeting of GFCC and States were sensitised on this issue
