What is a Reservoir?

A reservoir is a large, artificial or natural storage area used to collect and store water, usually created by building a dam across a river.

 

 

 

 

  • 30%+ of 166 major reservoirs have storage above 80% of capacity.

  • South-West monsoon was 13% deficient as of September 3.

  • 47% of 734 districts received deficient rainfall.

  • 13 reservoirs were full, including 5 in Maharashtra; 51 remained below 50% capacity.

  • Continued rainfall in the coming days may further improve reservoir storage.

 

 

  • Central (81.2%) and Western (80.4%) regions recorded the highest storage levels.

  • Overall reservoir storage stood at 56.76%, or 129.87 BCM of 183.565 BCM capacity.

  • 4 of 5 regions had storage above 60%, but Southern storage declined.

  • Overall storage remained below both last year’s level and the 10-year average.
