Storage of Important Reservoirs in the Country

 Central Water Commission (CWC) under Ministry of Water Resources is monitoring storage position of 81 important reservoirs spread all over the country, of which as many as 36 reservoirs are having significant hydro-power benefits with installed capacities of more than 60 MW each. The combined live storage in these 81 reservoirs at the beginning of monsoon i.e. 1st June, 2008 was 19 % of their designed capacity and stood at 18 % of the designed capacity as on 30th April 2009. The present storage is 67% of last year’s storage and 90% of last 10 years average storage during the same period. Out of these 81 reservoirs there are presently 42 reservoirs where this year’s storage is 80 % or less than the average of previous 10 years and in remaining 39 reservoirs the storage is more than 80 % of the average of previous 10 years. 

In order to derive the best possible benefits from the available water, Central Water Commission is keeping in touch with the Department of Agriculture and Co-operation and providing information of the weekly storage position to the Crop Weather Watch Group for evolving suitable crop strategies and also appraising the situation to various Departments and Ministries involved in Water Resources Planning. 

Basin wise storage position as on 30th April’09 is as follows: 

The storage position in 4 basins namely, Indus, Narmada, Rivers of Kutch, and West Flowing Rivers of South are better than average of previous 10 years. Ganga, Tapi, Mahi, Cauvery and Neighbouring East Flowing Rivers and Krishna basins are flowing close to normal and Godavari, Mahanadi & Neighbouring East Flowing rivers and Sabarmati are flowing deficient. 

Out of 36 reservoirs with significant hydro potential, 22 reservoirs have storage build up less than the average of last 10 years capacity.
