Ken - Betwa Link

 

[The Proposal: This link will cover a length of about 231 km. and provide irrigation in the downstream of proposed Daudhan dam, water short areas of Upper Betwa basin by way of substitution and also to enroute areas to the tune of 6.45 lakh hectares (1.55 lakh hectares in Uttar Pradesh and 4.90 lakh hectares in Madhya Pradesh) utilizing 3,196 Mcum of water.  It will also provide domestic and industrial water needs of 12 Mcum, besides an installed capacity of 72 MW of power.  About 37 Mcum will be used for meeting the transmission losses of the canal.  NWDA has already completed the feasibility study of this link.

Engineering Aspect:  An earthen dam is proposed on Ken at Daudhan 2.5 km upstream of the existing Gangau weir.  Two power houses, one (Power House No. I) at the foot of the dam and the other one (Power House-II) at the end of 2 km long tunnel, have also been proposed.  The total length of the link canal will be 231 km including a 2 km long tunnel in its head reach.  The design discharge of the link canal at the head is 72 cumecs.  The canal crosses several rivers/streams and finally outfalls into the existing reservoir viz. Barwa Sagar on Barwa river, a tributary of Betwa River. 

Environmental Issue: This project envisages construction of Daudhan dam 2.5 km upstream of the existing Gangau Weir.  The submergence under the project is expected to be of the order of 8,650 ha of which 6,400 ha will be the forest area.  About 8,550 people shall be affected in ten villages.
