Khadakwasla recorded 32mm rainfall till evening, while Panshet and Varasgaon recorded 10mm each.
Officials from the state irrigation department said that overcast conditions prevailed in the catchment areas from morning with fairly good spells recorded throughout the day. But to push water levels up, the catchments must receive continuous heavy spells, which will lead to an accumulation of rain water in the reservoirs.
The collective stock in the four dams was at 4.25TMC (14% of its capacity) on Saturday, which was about 1.19TMC more than last year’s stock of 3.06TMC. Officials said that they were monitoring water levels and rainfall activity in the catchments.
“None of four dams in Khadakwasla circle has recorded more than 100mm rainfall since June 1. Among the four dams, Varasgaon has recorded the highest rainfall of 64mm, followed by Panshet (56mm), Temghar (44mm) and Khadakwasla (34mm). Water stock in Temghar has depleted to 2%, while the live water stock in Panshet and Varasgaon is 12.5% and 15% respectively,” an official said.
Last year, the catchments had received heavy spells in the first week of July. “We are expecting a similar trend this year wherein a continuous rainfall in hilly regions of catchments is expected from this week. Water stock in four dams can reach to maximum capacities after catchment of each dam record rainfall between 1,000mm and 1,500mm,” the official added. “Catchments record maximum rainfall in July and August.”
The four dams can collectively hold live water stock of 29.15TMC. The irrigation department last week stopped release of water from Khadakwasla into the Mutha canal. The stock in dams has been kept reserved to meet drinking water requirements of the city and rural areas. The Pune Municipal Corporation (PMC) has also introduced once-a-week water closure across the city from last month as a precautionary measure.
Besides the four dams in Khadakwasla circle, fairly good spells of rain were also recorded in the catchments of Pavana and Mulshi.
