Rejuvenated 5 years in the past, the standard of water within the Dorekere lake in Bangalore South has deteriorated. In keeping with the civic company Bruhat Bengaluru Mahanagara Palike (BBMP), out of the 28.57 acre of the lake, 0.79 acre has been encroached by personal buildings and sheds.
Talking in regards to the biodiversity across the lake, Raghavendra B Pachhapur, Programme Supervisor with ActionAid Affiliation, India, stated, “Dorekere is a biodiversity wealthy lake with 110 chook species observed within the final seven years.

I used to be lucky to see a flock of Black-headed ibis with the younger ones within the lake. It’s seemingly that they have been raised right here at Dorekere. Flocks of Egrets and Purple-wattled lapwings are a delight to see right here, aside from the Black-winged stilt.”

Regardless of a wealthy biodiversity, Pachhapur added that the lake has poor water high quality. “Presently, the lake water is in an algal bloom stage. There’s progress of algae within the water because of giant consumption of vitamins within the type of sewage.

“Dorekere is a naturally well-placed lake. It’s surrounded by a hilly space and very best to gather pristine rainwater. I observed a small stream flowing in direction of the lake carrying rainwater from the encompassing areas two days after the rain within the space. BBMP ought to discover all the probabilities of harnessing rainwater to the lake. It’s sustainable and helps to keep up the wholesome lake ecosystem. Furthermore, the stroll path across the lake has been prolonged subsequent to the wetland by filling up silt in one of many stretches. It has decreased the waterbody house and I’m not certain if this was accepted within the detailed challenge report (DPR) by the Karnataka Tank Conservation and Improvement Authority (KTCDA),” Pachhapur stated.
On situation of anonymity, a resident staying close to the lake stated, “The lake is in a foul situation. It was good earlier than the pandemic however now one can see the carcass of animals and rubbish dumping close to the lake. The STP doesn’t work and civic authorities don’t preserve the lake.
