(b) if so, the measures taken by the Government to aid these States;

(c)  whether  the  Government  is  aware  that  most  districts  of  Andhra  Pradesh,  particularly  Rayalaseema  region witnessed high rain deficiency and drought-like conditions during the last year leading to low water storage for irrigation or power generation projects and may soon affect drinking water availability; and

(d) if so, the steps taken by the Government to mitigate these problems in the southern States?

Out of 150 numbers of reservoirs monitored by CWC, 42 are located in Southern region in States of Karnataka, Kerala, Andhra Pradesh, Telangana and Tamil Nadu. The details of live storage of these 42 reservoirs in comparison with live storage of previous year and average of last 10 years from 2.5.2014 to 11.7.2024 are given in Annexure-I .

Out of 42 reservoirs of Southern region, 4 reservoirs are from Andhra Pradesh & 2 Reservoirs are between Andhra Pradesh & Telangana. Comparing of live storage of current year of these reservoirs with last year are given at Annexure- II .

Further,  Weekly  Bulletin  is  shared  with  the  Water  Resources  Departments  of  concerned  states  and  also uploaded on the CWC website. This weekly bulletin is also shared with Crop Weather Watch Group (CWWG) of the  Ministry  of  Agriculture  and  Farmers  Welfare.  Representatives  of  CWC  also  attend  meetings  convened  by CWWG to review agricultural activities across the country and to suggest remedial measures to States in case of distress situation. Crop Weather Watch Group on Drought Management (CWWGDM) of Ministry of Agriculture & Farmers Welfare, Government of India holds meeting every week during Pre-Monsoon season to appraise status of Reservoir Storage in the country to enable CWWGDM to take further necessary action.

Also, whenever the percentage of departure of current storage of all reservoirs (under CWC monitoring) in a State falls below 80% of normal, advisory is being issued by CWC to the State Govt. & if current storage falls below 40% of last 10-year average, advisory is being issued by Secretary, Department of Water Resources, River Development & Ganga Rejuvenation, Ministry of Jal Shakti.
