Pic:Anvitha This time, I turn this column over to a friend, Anvitha, who is 17-years-old, and who is utilising her post-exam holidays to good effect, watching birds. Alas, it’s not always a thing of joy. Here’s her report from Lalbagh, in Bangalore: The fragrance of flowers attracts bees; so do the birds in Lalbagh attract bird watchers. Birdwatchers from all corners of Bangalore have always been drawn towards Lalbagh, but today the situation has  changed for the worse. Over the years, the number of  birdwatchers visiting Lalbagh has reduced due to the dwindling number…

Without much fanfare but certainly with a great deal of hope today afternoon we released the Salvinia weevil in two spots at the lake still infested with Salvinia Molesta. Salvinia weevils from Thrissur Releasing the weevils, 3rd June 2013 From the time Dr. Subramanya, UAS, Bangalore identified it last September, this invasive fern has been the bane of our lake. When the water level receded to mere puddles, the Salvinia began to dry in large tracts. We got it removed manually through BBMP's workers. Very many resident volunteers living around the lake pitched in strongly on several weekends. When it seemed…

The heavy rains on 31st May - 1st June helped raise the water level in several parts of Puttenahalli Lake by upto about 16 inches. With this about 65-75% of the lake bed is under water. We're waiting for a few more similar downpours to bring the level higher.  The Lake, 1st June 2013 (Pic: Usha Rajagopalan)The rains also cooled the place making the gardening weekend thoroughly enjoyable for all the volunteers. Over the two mornings, starting at 7 a.m., about 50 people coming from various parts of the city, helped in digging pits, planting shrubs, cleaning (plastics and other litter)…

Several of the visitors to the lake, have marveled at how the level has gone up in just two or three days of pre-monsoon showers. The reason of course is that the rain has been heavy this year and more because, for the first time, some of the surface run off from the Brigade Millennium road is getting diverted into the lake through the new conduit. The story doesn't end here.Visitors would have seen the enormous iron frame that was getting assembled on the ground between the security cabin and the gazebo. Thick iron rods have been placed over the…

In Part I of this series, Citizen Matters blew the lid off the IISc report that revealed the encroachment of a major Rajakaluve by the SEZ project by Manipal ETA Infotech Pvt Ltd. This part will explain the random changes made by the BDA in the status of the project land, resulting in a change of status, from being a ‘valley zone' to an industrial area. The site has seen some rapid changes in the last decade. In ‘95, BDA had classified this land as largely residential and park area. In 2005, BDA started revising its master plan. In the…

BBMP has taken up the rejuvenation of upstream lakes in the chain of seven lakes, of which Kaikondrahalli Lake is located just before Soulkere. A few months ago, the contractors had started to dewater the upstream lakes, which meant the sewage water present in these lakes had to be pumped out. Unfortunately diversion pipes were not in place at Kaikondarahalli lake so this polluted water was getting into our rejuvenated lake. So dewatering work was suspended to build the channels, and later the election code of conduct delayed the work further. With dewatering work restarted, we suddenly found that the…

It is said that Bangalore had more than 250 lakes and tanks. With the rapid expansion of the city, lakes have been disappearing at an alarming rate. However the story of Kaikondrahalli Kere is quite different. In the year 2009, Kaikondrahalli Kere situated on Sarjapur Road was practically dry and reduced to a swamp with some birdlife and a reasonable biodiversity. If it had been left as it was, it was just a matter of time before the lake died and all the bird life would have disappeared. In order to save the lake, a rejuvenation project was taken up…

Based on a total station survey done by Enzen Global in Aug. 2011, PNLIT got the BBMP to install a  new diversion channel (DC) to harvest surface run off from the Brigade Millennium road into the lake. After some unavoidable delays, complicated government procedures, worker issues, etc. the major DC was finally completed a month ago.The intermittent drizzle over the past couple of weeks indicated that the DC could work but we were not sure just how well it would till the downpour last night. Glimpses of the lake lit by lightning last night were exciting, raising our hope that…

Bangalore's water crisis has been averted for now, with a newly-formed committee appointed to look into the water supply to the city. One tmc ft (thousand million cubic feet) of water will be diverted from Hemavathi river to the KRS dam; currently there is one tmc ft of live storage existing in KRS dam as well. "Together, this two tmc ft water will meet the requirement of Bangalore till monsoon. The water requirement of Bangalore is 1.2 tmc ft per month," says a senior BWSSB officer, on condition of anonymity. The committee to oversee the process, was appointed after a…

One more lake in Bangalore seems to be nearing extinction. Kadugodi lake in Whitefield is the victim. And the encroachers belong to water mafia. The catchment area of this beautiful lake is being encroached upon by local politicians. They supply water to Whitefield apartments. The water is extracted from the lake and supplied to the apartments at Rs 2,000 per tanker. As if this is not enough, a new compound and buildings are coming up on the lake bed and catchment area. A few concerned citizens of this area have been trying to bring some limelight on the issue and…
