. The Chambal River had not until then been utilized for any major developmental works, and was proposed to be developed under a joint initiative of the state governments of Madhya Pradesh and Rajasthan.

. The river's drop of 625 metres (2,050.5 ft) between its source in Mhow and the city of Kota, which marks the exit of the river from its gorge section into the plains of Rajasthan, was seen as having great hydroelectric potential.

Stage I

The first stage of the development involved construction of the Gandhi Sagar Dam to a height of a 62.17 metres (204 ft) as a storage dam to store 7,322,000,000 cubic metres in Madhya Pradesh and utilise the stored water for hydroelectric power generation, followed by irrigation from the Kota Barrage in Rajasthan, 104 km downstream of the dam. Power generation at Gandhi Sagar Dam was through a powerhouse at the toe of the dam with a total installed capacity of 115 MW (divided into five units of 23 MW). The Kota Barrage, an earth and masonry structure 37.34 metres (122.5 ft) in height, was built to provide irrigation through a canal system, with two main canals on the right and left banks.. Construction of both projects began in 1953–54; both began functioning in 1960. The water received at the Kota Barrage is shared equally between Madhya Pradesh and Rajasthan for irrigation.

Stage II

The second stage of development involved the utilization of the water released from the Gandhi Sagar Dam through another dam structure, the Rana Pratap Sagar Dam

 of Rajasthan. Additional storage at this dam provides an increase in irrigation benefits from the Kota Barrage, increasing its area of irrigation from 445000 hectares (1,099,618 acre) to 567000 hectares (1,401,086.3 acre). In addition, a powerhouse at the toe of the dam provides an additional hydroelectric power generation capacity of 172 MW from four turbo generators, of 43 MW capacity each.
The second stage was completed in 1970. The power generated at the Rana Pratap Sagar Dam is shared equally with Madhya Pradesh, as the Gandhi Sagar Dam provides the stored waters for utilization at this dam.

Stage III

The third and final stage of development envisaged an intermediate dam between the Rana Pratap Sagar Dam and the Kota Barrage, called the Jawahar Sagar Dam

Jawahar Sagar Dam is a dam across the Chambal River. It is situated 24 kilometres south-west of Kota, Rajasthan, India.-References:*...

. This dam is a concrete gravity dam, 45 metres (147.6 ft) high, located approximately 23 kilometres (14.3 mi) upstream of Kota Barrage to its southwest, and provides a hydroelectric power generation capacity of 99 MW, with three generator units of 33 MW capacity each. This project was commissioned in 1972.

Features

Gandhi Sagar Dam is a masonry gravity dam with a height of 62.17 metres (204 ft) and a length of 514 metres (1,686.4 ft). The reservoir has a gross storage capacity of 7.32 billion cubic metres, with a live storage of 6.79 billion cubic metres corresponding to Full Reservoir Level (FRL) at 400 metres (1,312.3 ft). The spillway of the dam is designed for a discharge of 21,238 cubic metres per second. There are 10 gated spillway spans to pass the designed flood discharge. In addition, 9 river sluices have also been provided, but these have not been functional.

The hydroelectric power station is located at the toe of the dam on the right bank. The total flow through the five turbines is 311.15 m3/s. The power station has an installation of 142 MW with five turbines of 23 MW and one unit of 27 MW capacity. The power station is 65 metres (213.3 ft) long and 56 feet (17.1 m) wide. Power is supplied first to the local district and then to other regions of Madhya Pradesh and Rajasthan.

The Gandhi Sagar Dam and Power Station were built at a cost of about Rs. 2.3 billion.

, and is mostly used for fisheries development also.

The mean depth of the reservoir is 11.73 metres (38.5 ft), with a shore development index of 4.78, and a volume development index of 0.601 at the Full Reservoir Level. Scientific studies indicate that the reservoir is productive as regards fisheries, with the reservoir water indicating a moderate-to-high rate of primary productivity. Commercial Fisheries was initiated in 1959–60 in Gandhi Sagar, and has been credited as the best-managed reservoir in the state. Fish capture in the reservoir is prohibited between 16 June and 15 August.

The reservoir attracts a large number of migratory and non-migratory birds throughout the year, has been qualified under "A4iii criteria" by the IBA, as the bird congregation is of more than 20,000 waterbirds.

Suggested amendment

Analysis of hydroelectric power generation performed by the three power plants in the Chambal valley has been carried out by a non-governmental agency, based on statistics provided by the Central Electricity Authority under the RTI Act. The results indicate that the Gandhi Sagar reservoir attained its full storage condition only during five years of its five decades of operation. The energy generation of all the three power plants declined by 25% in the same period of 50 years, relative to the projected 50-year figures. Keeping these aspects in view, it has been suggested that the full reservoir level in the Gandhi Sagar Dam be reduced by suitable operational guidelines, which would enable the release of substantial submergence area for cultivation by the farmers who originally owned these lands.
