Ltd. 402, Bestech Chambers Commercial Plaza, B-Block, Sushant Lok-I, Gurgaon Phone: +91-124-4295383: www.rstechnologies.co.in Executive Summary of Gond Major Irrigation Project EXECUTIVE SUMMARY 1. GENERAL The purpose of Environmental Impact Assessment (EIA) is to assist in the decision making process and to ensure that the project options under consideration are environmentally sound and sustainable. This Environmental Impact Assessment (EIA) study has been conducted to identify possible environmental impacts and to suggest ways for mitigating or minimizing them. 2. OVERVIEW OF THE PROJECT Water Resources Department, Government of Madhya Pradesh proposes to construct an earthen dam across Gopad River at Jalpani village in Deosar Block of Tehsil Sarai in District Singrauli in the state of Madhya Pradesh. Gopad river is a right bank tributary of Son river, which ultimately joins river Ganga. Catchment area up to the proposed Dam site is 2095 sq km. The project proposes construction of a 37.31 m high earthern dam across Gopad River near Jalpani village to irrigate a total designed area of 28,000 ha of Culturable Command Area (CCA) and benefiting 147 villages. The creation of reservoir due to construction of dam will lead to submergence of 1263.401 ha of land, of which, 327.34 ha is unirrigated private land, 356.97 ha is forest land and 534.83 ha is government land. Total 9 villages are coming under submergence due to proposed scheme. The project is envisaged to have a gross storage capacity of 100.35 MCM and the live storage capacity of 96.49 MCM. The location of the project is shown in Figure 1. The salient features of the project are given in Table 1. The layout map of the project is given at Figure 2.

ENVIRONMENTAL BASELINE STATUS 5.1 Physiography To understand the topography of the study are, Digital Elevation Map, Relief map, and slope map were prepared from Digital Elevation Model (DEM) Digital Elevation map shows that elevation in the study area varies between 304 and 823m above msl. Majority of the study area falls under Moderately sloping to Gently sloping categories constituting nearly 88% of the study area. 5.2 Meteorology Average mean maximum temperature of 41.10C was recorded during the month of May and average mean minimum temperature of 12.70C during the month of January. The mean annual average rainfall of Singrauli and Sidhi district was recorded as 1360.67 mm. The Relative Humidity is generally low throughout the year, except during monsoon months when average relative humidity is close to 82% in the month of August. The wind speed is higher during the pre-monsoon period as compared to the post-monsoon period. The average maximum wind speed of 17.8 Kmph is observed during the month of June.
