(b) whether the Government has assessed the reasons and impacts of the degradation of the catchment capacity of dams in Rajasthan and Maharashtra and if so, the details thereof;
(c) whether the Government proposes any further Dam Rehabilitation and Improvement Projects (DRIP) and if so, the details thereof; and

ANSWER
THE MINISTER OF STATE FOR JAL SHAKTI
(SHRI BISHWESWAR TUDU)
(a) Central Water Commission (CWC) is monitoring live storage status of 140 reservoirs of the country including 5 dams of Rajasthan and 29 dams of Maharashtra on weekly basis and is issuing weekly bulletin on every Thursday. The total live storage capacity of these 140 reservoirs is 175.957 BCM which is about 68.25% of the live storage capacity of 257.812 BCM estimated to have been created in the country. Abstract of CWC weekly bulletin issued on 24.03.2022, showing storage position of monitored dams of Rajasthan and Maharashtra is given at Annexure-I.
(b) No such specific study has been conducted. It is generally observed that the main reasons for degradation of the catchment capacity of the dams, wherever it happens, are the scattered and uneven rainfall and change of land use in catchment area of dams, resulting in less inflow of water in the river.
(c) & (d) Govt. of India has launched the Dam Rehabilitation and Improvement Project (DRIP) Phase II & III with the objective to improve the safety and operational performance of selected dams along with emphasis on institutional strengthening. This scheme has 19 participating States (including Rajasthan and Maharashtra), and three central agencies. The total estimated cost of DRIP, Phases II & III scheme is Rs. 10,211 crore with rehabilitation provision of 736 dams. The scheme is of 10 years duration. Each Phase has external assistance of US$ 500 million. Phase II of the Scheme has co-financing provision, wherein external assistance amounting US$ 500 million is being equally shared by the World Bank and the Asian Infrastructure and Investment Bank. DRIP-II scheme has been declared effective from October 2021.
The State-wise number of dams and estimated cost proposed under DRIP Phases -II & III is given at Annexure-II.
State Governments of Rajasthan and Maharashtra have proposed rehabilitation of 189 and 167 dams respectively at an estimated cost of Rs. 965 crore and Rs. 940 crore under DRIP, Phases-II & III.
