3.0 THE DETAILS OF THE FUNCTIONS OF CWMA ARE GIVEN BELOW:-
The Authority shall exercise such powers and shall discharge duty to do any or all things necessary, sufficient and expedient for securing compliance and implementations of the Award of the Tribunal as modified by the Hon;ble Supreme Court vide order dated the 16th February, 2018 including:
(i) storage appointment, regulation and control of Cauvery waters:
(ii) Supervision of operation of reservoir and with regulation of water releases there from with the assistance of Regulation Committee:
(iii) Regulated releases by Karnataka at the inter-State contact point presently identified as Billigundulu gauge and discharge station, located on the common border of Karnataka and Tamil Nadu.
The Authority shall perform inter alia, the following functions, namely:-
- The Authority at the beginning of the water year, i.e. first June each year would determine the total residual storage in the specified reservoirs. As, it is not possible to know the amount of season-wise river flows which will be available during a season, it will be assumed that the inflows will be according to 50% dependable year (yield 740 TMC). The share of each State will be determined on the basis of the flows so assumed together with the available carry-over storage in the reservoirs. The withdrawals will be allowed during the first time interval of ten days of the season on the basis of the share worked out for each party State, limited to the water requirements during the same period indicated by each party State by placing an indent of water demand with Cauvery Water Regulation Committee.
- The Authority will take stock of the actual yield in the basin at the end of the previous time interval as well as the utilization or releases and storage built up during the interval and assess the trend of inflows and authorize withdrawals to the States for the subsequent time interval accordingly. For giving effect to the aforesaid provision, the Authority may have to repeat this exercise for two or more time intervals.
- The Authority shall ensure the implementation of the Award of the Tribunal as modified by the Hon’ble Supreme Court vide Order dated 16th February, 2018 including the carry-over storage during good year and the water releases for environmental purposes. The Authority, through the Regulation Committee and with the help of Central Water Commission, and other Central or State organizations as necessary will identify situations of distress in the river basin. Distress caused by diminution of water flows during the period will be shared by the party States after the distress conditions and their extent is determined by the Authority, keeping in view water shares allotted to parties.
- The following important reservoirs in the river basin, namely, Banasurasagar in Kerala; Hemavathy, Harangi, Kabini and Krishnarajasagara in Karnataka; and Lower Bhavani, Amaravathy and Mettur in Tamil Nadu shall be operated in an integrated manner by the concerned State under the overall guidance of the Authority for each ten days period throughout the year to meet the seasonal water requirements of the party States for irrigation, hydro-power generation, domestic and industrial uses, etc. The remaining quantities of the surplus water shall be conserved as far as possible and spillage of water shall be reduced to the minimum.
- The Authority shall maintain an account of cropping pattern, area cropped and area irrigated for each party State. The Authority shall also maintain an account of domestic and industrial water usage by each party State.
- The Authority shall set up a well-designed communication network in the Cauvery basin for transmission of data and a computer based control room for data processing to determine the hydrological conditions including distress, if any. For this purpose, it may utilize the latest technology. For operational purposes, this work may be entrusted by the Authority to Central Water Commission or any other Central or State Government organization.
- On the beginning of irrigation season which is 1st June of every year, all the party States through their representatives in the Authority shall submit an indent for the supplies required by them at each reservoir site (capacity 3 TMC and above) for the month of June broken in ten daily intervals. The Authority will examine reasonableness of the indents keeping in view the cropping pattern and extent of area to be irrigated and order releases keeping in view the overall ceiling prescribed by the Tribunal and modified by the Hon’ble Supreme Court vide Order dated 16th February, 2018 for the month after determining the available carry-over storage and taking into consideration the likely inflows during the month. The Regulation Committee shall release water on ten daily bases as ordered by the Authority.
- In case of deficiency in the water availability during any month as reported by the Regulation Committee, the Authority will consider reduction in the indent of the parties in proportion to the quantities allocated to each State by the Tribunal as modified by the Hon’ble Supreme Court vide Order dated 16th February, 2018 for the designated crops.
- The Regulation Committee shall keep a watch on the actual performance of the monsoon during each ten daily interval and report position to the Authority indicating therein the extent of variation from the normal. The Authority on receipt of such information will consider any change in the release ordered by them earlier. Similar exercise will continue as the monsoon progresses during the succeeding months till the end of the water year which is 31st May of every year.
- The Authority shall ensure that the respective State Governments should construct proper hydraulic structures at all important anicut sites in the river basin with a provision of appropriate regulation mechanism. Besides, regular monitoring of the withdrawals at such diversion structures on the part of the State would be necessary.
- The Authority may direct party States to furnish data in respect of carry-over storage in reservoirs, including inflows and outflows, rainfall data, the area irrigated and water utilized.
- The Authority shall arrange collection of data for important rain gauge stations maintained by Indian Metrological Department or Central Water Commission or States in the Cauvery basin, as also inflow data measured at important nodal points on the Cauvery river system through the Cauvery Regulation Committee which will suitably compile the rainfall data for different monsoon seasons along with the inflows measured at different sites.
- The Authority or any Member or any representative thereof shall have power to enter upon any land or property upon which any hydraulic structure or any work of gauging or measuring device has been or is being constructed, operated or maintained by any agency in the Cauvery basin.
