However, water release to Odisha will be regulated by Tripartite agreement reached between three co-basin States i.e. Bihar (Now Jharkhand), West Bengal & Odisha. 3 Salient Features of Interstate Agreements. A. Bipartite Agreement. A Bipartite agreement was drawn on 17 th January, 1976 between the Chief Ministers of Bihar and Orissa. The salient points of the Agreement is as below. The joint works consists of (a) Kharkai Dam over river Kharkai at Ichha (Jharkhand), (b) Galudih Barrage over Subarnarekha at Galudih and (c) Galudih right bank canal to feed Odisha’s share of water. Some features of Bipartite Agreement are: - Sl.

(a) all excess over 0.16 MAF in the non-monsoon flow at Galudih Barrage will be shared between Bihar and Odisha in the ratio of 3:5. (b) Till the completion of Khrkai Dam, if the share of Odisha in non-monsoon flow is less than 0.23MAF at Galudih, the shortfall will be made available from judicious operation of the Chandil reservoir. (c) There will be a Technical Committee and a Joint Control Board for regulation of the works. 4 B. Tripartite Agreement:- A tripartite Agreement was reached on 07.08.1978 between the Chief Ministers of Bihar, Odisha and West Bengal on utilization of the water resources of Subarnarekha Basin on the frame work of Bipartite Agreement. The salient additional features of the TPA are given below. Bihar Odisha West Bengal 1 Share of co-basin status on 75% 2.7 2.9 5.9 dependable yield below Kokpara Lakh Acft. LakhsAcft. Lakhs Acft.

Three co-basin states requested Govt. of India (GOI) to meet the cost of the flood moderation portion cost of the dam, which was turned down by the GOI. The share cost is to be borne by Odisha State from its F.C. budget. The %age of sharing the cost agreed between Odisha and West Bengal. Bihar does not share flood storage cost which is around 26.40 % of the cost of the entire Dam. Though clause 2.3.4 of TPA stipulates simultaneous execution of Kharkhai and Chandil Dam and Galudih Barrage along with Right Bank Canal, Kharkai Dam is lagging behind. A joint control board and Technical Committee will be formed for execution of the joint works. A joint regulation committee will be formed under the Chairmanship of CWC for effective regulation of the joint works. 5 C. Agreements between Technical Officer of Govt. of Odisha and Govt. of Bihar Further, agreement was reached on 20.2.1991, between Engineers of Bihar and Odisha on withdrawal pattern from Ichha reservoir based on the guidelines of TPA. The salient points are summarized below. Particulars. Monsoon drawal Non-monsoon drawal. 1. Drawal from 28% Drawal. In excess 72% Ichha reservoir of 28% can be made during draught years. 2. Non-monsoon - 247.4 MM 3(Million cubic Mtr.) drawal in 75% (From Nov. To June). dependable year at Galudih. Joint regulation Committee (JRC) will formulate rules and regulations for judicious operation of the reservoir. A NOTE ON COMMITTEES FORMED AS PER TPA. 1.
