Executive Summary of Ghaghara-Yamuna The National Water Policy of Government of India provides that water should be made available to water short areas by transfer from other areas including transfers from one river basin to another, based on a national perspective, after taking into account the requirements of the areas/basins. Accordingly, long distance inter-basin transfer of water from water surplus basins to water deficit basins has been mooted in our country in order to reduce the regional imbalances in the availability of water. A National Perspective Plan (NPP) was formulated in the year 1980 by the Union Ministry of Irrigation (now Ministry of Water Resources) and the Central Water Commission identifying a number of inter-basin water transfer links in respect of both Peninsular rivers and Himalayan rivers of the country. The Peninsular Rivers Development and the Himalayan Rivers Development Components put together were expected to create an additional irrigation potential of 35 million hectares besides hydropower potential and other benefits. The interlinking of Ghaghara (Karnali)-Yamuna rivers is one of the important interdependent and international link proposals of Himalayan Rivers Development Component of the NPP. This report deals with feasibility studies of Ghaghara-Yamuna link project. The objective of preparation of the feasibility report is mainly to facilitate firming up of the proposals and for discussions among the concerned States/Countries to arrive at broad agreements on the quantum of diversions and utilisations of water, mutual consensus for carrying out the work in the respective countries, sharing of cost and benefits etc. This report has been prepared keeping in view the comments offered by the concerned State Govts./Deptts. on pre-feasibility study of the Karnali-Yamuna link project. The comments of the State Govts. and clarifications thereon by NWDA are furnished at Appendix-1. The preliminary feasibility report of Karnali-Yamuna link canal project (Technical Study No. PFR(H)/6/94) was prepared and circulated amongst the members of TAC and to the concerned State Govts. in September 1996. The pre-feasibility report of Karnali-Yamuna link project was discussed in 26th & 27th meetings of TAC of NWDA and finally accepted by the TAC in its 28th meeting held on 27th Oct. 1998. The Ghaghara(Karnali)-Yamuna link project, an interdependent link, envisages diversion of surplus waters from river Karnali at Chisapani dam after taking contribution from Mohana river (a tributary of Karnali river) and the water saved in Karnali at Chisapani dam due to taking over its existing and ongoing commands by the proposed Gandak- Ganga link project on substitution basis. The entire existing and ongoing commands of Sarda Sahayak Pariyojna, part Sarju Nahar Pariyojna and the commands of 6 (six) number existing/ongoing pump canals, which, at present, are receiving waters from Ghaghara, will be substituted by surplus waters of Gandak through the proposed Gandak-Ganga link and regeneration received in the downstream of regulating dam from substantial quantum of water released for domestic and industrial water needs in the downstream of regulating dam respectively. The available water in the upper catchment of Ghaghara (Karnali), will be first stored in the Chisapani Multipurpose reservoir proposed by HMG of Nepal across river Karnali. The 1 releases from this reservoir after generating power will again be stored/picked up at Chisapani regulating dam proposed 8 km downstream of Chisapani dam in Nepal. A report on Karnali (Chisapani) Multipurpose Project was prepared by M/s. Himalayan Power Consultants for Govt. of Nepal in December 1989. As per the report, a site was identified for a storage dam at Chisapani in Nepal and detailed investigations were carried out by the same Agency. The project is proposed to be conceived as a joint venture between Nepal and India to integrate with the Ghaghara(Karnali)-Yamuna link canal. The Ghaghara(Karnali)-Yamuna link is an interdependent link since in the Himalayan Rivers Development Component proposal, the Gandak-Ganga, Ghaghara(Karnali)-Yamuna, Sarda-Yamuna, Yamuna-Rajasthan, Rajasthan-Sabarmati, Chunar-Sone barrage and Sone Dam-Southern Tributaries of Ganga (STG) link canal projects are proposed for water resources development as interdependent links and would entirely be worked on substitution basis. The Ghaghara(Karnali)-Yamuna link canal is proposed to offtake from the reservoir of right bank of proposed regulating dam located in the downstream of proposed Chisapani dam at an FSL 196.3 m and is proposed to outfall into river Yamuna near village Balrai which is about 30 km from Etawah of Uttar Pradesh. The total length of the link canal is about 417 km, out of which about 102 km lies in Nepal and remaining about 315 km in India. The link project envisages diversion of combined quantity of 24316 Mm3 of water for meeting the requirements of existing and ongoing commands of the project taken over by the link, intensification, enroute demands of the link for domestic and irrigation use in new command areas in Nepal (western side) and Indian territory including transmission losses. After meeting the above enroute demands, the remaining 1415 Mm3 of water is proposed to be fed to Yamuna river which would be further utilized through Chunar-Sone barrage and Sone dam – STG links for benefiting the States of Uttar Pradesh, Jharkhand and Bihar. The link project will provide total annual irrigation to an area of 27.84 lakh ha. Out of this, 2.54 lakh ha annual irrigation at 240% intensity of irrigation is proposed to be provided in the western side of Nepal and remaining in India, which includes taking over existing command in the link, intensification and new command area. From the total annual irrigation of 25.30 lakh ha proposed to be provided in Indian territory, 13.60 lakh ha annual irrigation under existing & ongoing commands of Sarda Canal System including Lower Ganga & Parallel Lower Ganga canal system is proposed to be taken over by this link, 7.77 lakh ha is proposed for intensification where intensity of irrigation under existing and ongoing commands is less than 100% and about 3.94 lakh ha annual irrigation has been proposed in new additional command area at 100% intensity of irrigation as per guidelines of TAC of NWDA. Besides, 2519 Mm3 of water is proposed to be utilised in eastern side of Nepal for irrigating 2.04 lakh ha annually through proposed eastern Chisapani canal at 240% intensity of irrigation. The total cost of the link project as a whole based on 2003-04 price level has been estimated to Rs 32982.37 crore comprising of Rs. 21559.85 crore for Head works and Rs.11422.52 crore for canals & canalization. The total annual benefit from the link project for irrigation as a whole in India and Nepal is worked out to Rs. 4314.06 crore and the power benefit from the project works out to be Rs. 3133.80 crore. Thus, the total annual benefit of the project from irrigation and power are worked out to 2 Rs. 7447.86 crore. The annual operation and maintenance cost of the project is estimated to be Rs. 3440.16 crore. The Benefit-cost ratio and Internal rate of return (IRR) of the project as a whole is estimated as 2.16 and 15% respectively. The Benefit- cost ratio of the project for India works out to 1.74. The Internal rate of return (IRR) of the project for India considering the life of the project as 100 years has been computed without accounting for the distributional and employment effect, works out to 13%. The B.C. ratio and IRR for Nepal is estimated as 2.39 and 15% respectively. 3 780 790 800 810 820 290 290 PLATE – 1.3 BANBASA BARRAGE N CHISAPANI DAM PILIBHIT NARORA BARRAGE BAREILLY GIRIJA BARRAGE REGULATING DAM SARDA BARRAGE BUDAUN 280 280 LAKHIMPUR LEGEND SHAHJAHANPUR •INTERNATIONAL BOUNDARY •STATE BOUNDARY U T T A R P R A D E S H •DISTRICT BOUNDARY • STATE CAPITAL SITAPUR BAHARAICH •DISTRICT HEAD QUARTER ETAH •RIVER HARDOI •LINK ALIGNMENT FATEHGARH •DAM / BARRAGE MAINPURI •PROJECTS EXISTING ONGOING PROPOSED •MAJOR KANNAUJ 270 270 •MEDIUM AGRA BARABANKI •CANAL ETAWAH •BARRAGE PROPOSED BY NWDA AURAIYA LUCKNOW •ENROUTE COMMAND PROPOSED BY NWDA BHIND UNNAO SCALE GWALIOR KANPUR 10 0 10 20 30 40 50 Km RAEBARELI PANCHNAD DAM DAL MAU PUMP CANAL 260 ORAI 260 HAMIRPUR jk"Vªh; ty fodkl vfHkdj.k FATEHPUR NATIONAL WATER DEVELOPMENT AGENCY ?kk?kjk & ;equk fyad d s lkehI; {ks= ds varxZr ifj;kstuk ekufp= VICINITY MAP OF GHAGHARA-YAMUNA LINK PROJECT DATIA js[kkadd izLrqrdrkZ BANDA V.P.
