To start with, it was proposed that the Chambal Project in Rajasthan and Madhya Pradesh and · the Hirakud Project in Orissa be taken up for such studies, in association with the officers concern ed of the State Governments. The Chief Ministers of Rajasthan and Madhya Pradesh approved of the proposal and the following report.represents the result of the studies·made in respect of the Chambal Project in the two States. · ' .- . .. The study excludes from its purview all problems relating to the construction of the project which is nearing completion. It concerns itself mainly with the. operation of the project, all developments flowing from it and .the measures relating to maxi mising benefits from the project. The factual data in the report are as obtained by the Group from published reports, from the officers of the States, or from the Secretary, Chambal Control Board. The comments and recommendations of the Group have been clearly indicated. · The Project 2. The Chambal Valley Development has been sanctioned in three stages as follows : Stage I, sanctioned in 1954, includes a dam and power house at Gandhisagar, necessary transmission lines and sub stations for utilising the power to be generated, a diver.J sion barrage at Kotah and two canals for the irrigation of 11 lakh acres in Rajasthan and Madhya Pradesh .. Stage II, sanctioned in 1961, provides for .a dam and power house at Rana Pratap Sagar; with the additional storage at this dam, the annual irrigation was expected to in crease from 11 to 14 lakh acres. • I 2 Stage III, sanctioned in 1962, is for a ~ ~d P?Wer house at Jawaharsagar. with a short transllllSsiOn line to con nect the Jawahar sagar power station with the transmis sion system between Gandhisagar and Kotah. 3. Apart from the project in three stages, as described above, . some additional estimates relating to the developments on the Chambal have been sanctioned separately. Brief particulars of the development, as sanctioned so far, are shown below. (a) Particulars ·of dams, canals and power houses Gandhi Rana Pra· Jawabar Kotah.
