<P> The dam has attained a height of EL. 121.92 m, the crest level of the spillway . The gates are yet to be erected to attain the FRL of EL 138.68 m for which clearance is required from the Supreme Court after the Grievance Redressal Committee submits its report on completion of R & R up to that elevation . Top level of dam to be attained is EL 146.50 m . </P> <P> Subsequent to the Tribunal award and approval to the project in 1987 by the Ministry of Water Resources with due clearances from the ministry, implementation of the Sardar Sarovar Project (SSP) was taken up as the terminal project on the main stem of the Narmada, in Gujarat, to use the share of allocated water to Gujarat and Rajasthan . The concrete gravity dam of 1,210 metres (3,970 ft) length and 163 metres (535 ft) height above foundation with storage capacity of 7,700,000 acre feet (9.5 km) and reservoir length of 214 kilometres (133 mi) extending into Gujarat, Maharashtra and Madhya Pradesh is designed to provide an annual irrigation of 18,000 square kilometres (6,900 sq mi) in Gujarat (covering 3360 villages of 62 talukas in 14 districts), 4,260 square kilometres (1,640 sq mi) in Rajasthan and hydel power generation of 1450 MW . As a result of construction of the dam, over 48,269 families (7000 families were assessed in 1979 by the Tribunal) will be affected, as per the latest figures of NCA, in the three States spread over 244 villages (4 fully and 240 partially, 39369 in MP in 192 villages, 4163 in Maharshtra in 33 villages and 4737 in Gujarat in 19 villages); the total area affected being 375.33 square kilometres (144.92 sq mi). The submergence area is broadly divided into two areas . First is fully tribal, which covers the initial reach of about 100 or so villages, which are almost 100% tribal and hilly . They include all the 33 villages of Maharashtra (in Nadurbar District), all 19 of Gujarat and many of the Madhya Pradesh . The second part of the submergence area is the mixed population area on the Nimad plains, with a very well developed economy that is well connected to the mainstream . Considered as the largest water resources project of India in terms of benefits, some of the special features of the project are the following: </P> <Ul> <Li> the spillway discharging capacity, at 3,070,000 cu ft / s (87,000 m / s), is the third highest in the world </Li> <Li> With 1133 m3 / s (40,000 ft3 / s) capacity at the head regulator and 532 kilometres (331 mi) length (458 kilometres (285 mi) in Gujarat and 74 kilometres (46 mi) in Rajasthan) with 75,000 kilometres (47,000 mi) length of distribution system including field channel, the Narmada Main Canal is the largest irrigation canal in the world . </Li> <Li> The project aims at supplying 3571, 000 m3 / day of drinking water (2900, 000 m3 / day for domestic consumption and 671,000 m3 / day for industrial consumption) to 8215 villages and 135 towns in Gujarat, which are suffering from acute shortage of water . Also, the project aims to provide drinking water facilities to a population of about 1,371,000 in 1107 villages and two towns in Jalore district and Barmer district of Rajasthan . </Li> <Li> It has the lowest ratio of submergence to area irrigated, 1.65% of CCA against an average of 4 to 5% of other major irrigation projects . </Li> </Ul> <Li> the spillway discharging capacity, at 3,070,000 cu ft / s (87,000 m / s), is the third highest in the world </Li>
