MUMBAI - The water level in 161 key reservoirs across India rose significantly by 76% on year to 66.449 billion cubic metres as of Thursday, according to data from the Central Water Commission. The current level is 36.42% of the total live storage capacity of 182.444 billion cubic metres. 

The water levels also rose from the previous week's level of 58.030 billion cubic metres, the data showed. According to data collated by Informist, the current water level in key reservoirs is at a six-year-high. The water level as of Thursday was 52.84% above the 10-year average for this period.

Water levels in key reservoirs rose on year due to an early onset of the southwest monsoon. The monsoon onset over Kerala on May 24, eight days ahead of its normal date of Jun. 1. Following its initial advance across the northeast and south India, the monsoon stalled from May 29 to Jun. 15, which led to deficit rainfall across the country during the first fortnight of June.

However, it re-entered its active phase by Jun. 16 and covered entire India on Sunday, nine days before the normal date of Jul. 8. According to the weather bureau's data, India received 9% above normal showers at 180 millimetres in June. In its monthly weather outlook, the weather department has forecast above-normal rainfall for the country in July at over 106% of the long-period average.

Reservoirs in the eastern region held 6.696 billion cubic metres of water, which is 30.83% of their total live storage capacity. This was higher than 21.08% held by the reservoirs in the same period a year ago. The eastern region comprises Assam, Jharkhand, Odisha, Tripura, Nagaland, West Bengal, and Bihar.

The water level in the southern region was 24.968 billion cubic metres, which is a six-year-high level.
