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 11 % of their designed capacity and stood at 35 % of the designed capacity as on 30th July 2009. The present storage is 112% of last year’s storage and 102% of last 10 years average storage during the same period. Out of these 81 reservoirs there are presently 30 reservoirs where this year’s storage is 80 % or less than the average of previous 10 years and in remaining 51 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 July’09 is as follows:
The storage position in Narmada, Mahi, Sabarmati, Krishna, Cauvery and East Flowing Rivers (EFRs) and West Flowing Rivers (WFRs) of South basins are better than average of previous 10 years. Mahanadi and Neighboring East Flowing Rivers, Rivers of Kutch and Tapi basins are flowing close to normal and Ganga, Indus, Godavari, are flowing deficient.
Out of 36 reservoirs with significant hydro potential, 18 reservoirs have storage build up less than the average of last 10 years capacity.
