Record rainfall in Bhopal and neighbouring Sehore saw Upper Lake swell to an all-time high level for the month of June at 1,663.50 feet on Thursday. This level has never been reached in the history of Upper Lake in the month of June after it was turned into a reservoir by construction of the Bhadbhada Dam in 1965, Bhopal Municipal Corporation authorities told HT.
Though the rainfall intensity decreased in capital city, its surroundings and neighbouring Sehore district, the water from catchments and the feeding rivulets including Kolans and Uljhawan continued to pour into the massive manmade water body, quickly filling up its gut. On Wednesday, the water level in the lake had stood at 1,662.00 feet, which means that within 24 hours, 1.5 feet of water rushed into the lake.
The full tank level of Upper Lake is 1666.80 feet and few spells of heavy rainfall in the catchments is expected to fill up the lake far earlier than any previous years, it is being surmised.
Assistant engineer of BMC Rakesh Nigam, who is in-charge of Upper Lake, told HT that heavy rainfall in catchments during last few days and the fact that the level of the lake was already quite high before the onset of monsoon this year, led to the extremely fast filling up of the lake. At summer end (May end), the water level in lake was 1,659.60 feet, which was in itself quite high. The fact that water supply from Narmada project has started partially in the city has led to lesser utilisation of water from Upper Lake, keeping its level high at summer end.
In duration of last month, four feet water has collected in the lake, swelling it up almost to the brim.
