Indira Sagar Project is a Multipurpose project will have the largest storage capacity in the country.
It will have an installed capacity of 1000 MW and annual irrigation of 2.65 Lakh Ha. on a CCA of
1.23 Lakh Ha. The project provides regulated releases of 8.12 MAF to Gujrat ex-Maheshwar project
after power generation at down stream projects viz., Omkareshwar and Maheshwar project in Madhya
Pradesh.
Indira Sagar Project is the key project on Narmada river providing excellent storage site. The Dam
is proposed on the main river near village Narmadanagar of Punasa Block in the District.
Omkareshwar and Maheshwar projects are proposed in the downstream to utilize the regulated
releases of Indira Sagar project of irrigation and power generation. Hence, the cascade of Indira Sagar,
Omkareshwar and Maheshwar projects, together,are known as"Narmada Sagar Complex".The total
drainage area at the proposed dam site of Indira Sagar Project is 61642 Sq. Kms. The main dam is
located on quartzite's of reddish colour and with small interbedding of silt stone of purple colour
belonging to Vindhyans (Super Group). The power house is located on the stable right bank in deep
pit which is geologically less disturbed. The project command area encompasses the Narmada Sone
lineament. The command area is mostly composed of basaltic lava flows. These flows are designated
as deccan traps. The thickness of lava flows ranges from 6.5 m to 30 m with presence of vesicular
and amydaloidal in basaltic flow with appreciable weathering on top. Detailed seismological studies
have been got done and based on the recommendation of the Dam Review Panel, detailed designs for
the dam have been prepared by the Central Water Commission. A network for ten seismological
stations is proposed to be established through Indian Meteorological Department covering the area of
the project of Narmada Sagar Complex.The dam is proposed to be 92 m (302 Ft.) high and 653 m
(2142 ft.) in length with a slightly curved alignment of 880 m radius across river Narmada near village

proposed to takeoff from 92.10 Km of the main flow
canal. It is 83 Kms. long and involves 38m lift. It is
proposed to irrigate about 24282 Ha. of land in higher
elevated areas of West Nimar District in Bhikangaon
and Kasarawad Tehsils.A provision for further
expansion to irrigate about 26000 Ha. of land by lift is
also considered in the basin of intake components of
Indira Sagar Project Canal.The submergence of Indira
Sagar Project is 91348 Ha. including forest and revenue
land extending to 249 villages of East Nimar,
Hoshangabad and Dewas Districts. Out of 249 villages
going under submergence, 12 are forest villages and the
remaining 237 are revenue villages. The submergence
area is consisting of forest area of 41420 ha. , cultivated
