Hesaraghatta Lake sees water after 6 yrs

After nearly six years, Hesaraghatta Lake, one of the biggest water bodies near Bangalore, is almost full, thanks to the copious monsoon rains this year. The recorded water level on the lakebed is up to 8.5 feet.

The lake, which resembled a barren land for several years, has now brought joy to villagers in the area. People bring their cattle for grazing and many cows  have a good time in the wateras well. Local boys can also be found fishing.

A Venkatesh, a local resident, said he had seen the lake with so much water after nearly 20 years. “I have seen this lake since my childhood. People from Bangalore used to come here as it is a sightseeing spot. But for the past few years, there was absolutely no water in the lake. But in the last three months, the number of visitors has increased, which is a good sign,” he added.

According to M Kempaiah, assistant executive engineer, Bangalore Water Supply and Sewerage Board, the lake's water level was at its peak during July-end this year and reduced to seven feet recently due to evaporation. He said that 1988 was the last time that the lake was filled to capacity, but later, due to encroachment of the lake’s inlet and outlet channel routes, the water level began to decline.

“For many years, the water level remained at five to six feet and for more than six years, there was absolutely no water. This year, due to excessive monsoon rains, the lake has rejuvenated to a certain extent, recording more water level than usual,” Kempaiah said.

Hesaraghatta Lake receives water from the River Arkavathi and has a capacity for storing nearly 1,000 million cubic feet of water. It was the first source of water supply to Bangalore City and subsequently water from Tippagondanahalli (TG Halli) was drawn to supply to the City.

But ever since the first Cauvery Water Supply Scheme was commissioned in 1974, drawing water from Hesaraghatta and TG Halli was reduced and suspended by BWSSB.
T Venkataraju, engineer-in-chief, BWSSB, said there were 21 borewells sunk on the lakebed, and for some time between 2008 and 2011, water from the borewells was supplied to over 3,000 households in the Dasarahalli Assembly constituency.

But the water from these borewells too dried up and the Board started supplying water from the Cauvery scheme, he added.

Cauvery Neeravari Nigam has also taken up work to improve the channels of the lake which connects to many smaller lakes in Hesaraghatta. The lake is spread across 1224.21 acres and has over 184 tanks on the upstream.
