Report on the volunteering weekend at Puttenahalli Lake

Saturday, 9th March 2013

With some 20 volunteers responding to our call to remove the drying aquatic weed from the lake bed, it was a most satisfying morning today!

Their enthusiasm was infectious and several people stopped jogging/walking to see what they were doing, then joined them to remove the drying Salvinia Molesta. Working with a rake, a spade or simply scooping up the weed with bare hands, they filled plastic bags, formed a line on the slope, handed each bag over the grill where others waited to cart them away. The dry Salvinia can be used for mulching or composting. We have opted to compost them by laying them along the boundary fence.

Despite working hard for over two hours, only a patch of ground has been cleared. With more of you joining us tomorrow (and on subsequent weekends) we should be able to accomplish our mission of clearing the lake bed and getting it ready for the monsoon.

Another good morning at the lake today with some new volunteers joining us. 

Y/day’s experienced hands were surprised to see fish in parts of the lake, below the weed. A few were dead but thankfully, most were alive. It was not possible to pull the weed out since the fish were coming with it so the kind souls made holes in the Salvinia for the fish to breathe. A couple of volunteers transferred the fish to the pools of water, carrying them in a bucket of water. It must have been a poignant moment for our volunteers renewed their effort to pull out more Salvinia and clean the ground. 

It was a hot morning but all of us felt the satisfaction of having done a good job. 

Dedicated work
Slow and steady

Heart felt thanks to all volunteers. We look forward to having you over next weekend. Do share your experience in this forum and with your family and friends and get them over as well!

Explained: How Mumbai is losing its tree cover to infrastructure projects

Mumbai's landscape is changing with big infra projects. Experts suggest better use of government plots and improved street design to retain green cover.

Long before Mumbai’s relentless summer even began this year, the city was already simmering. In March, Mumbai was hit by a severe heatwave, with the temperature reaching a five-year high of 40° Celsius. As rapid urbanisation and a flurry of infrastructure projects replace dense tree cover with steel and mortar, heatwaves seem to have gone from being rare occurrences to an annual threat.   The Mumbai Metro Rail Corporation Limited (MMRCL) cut a whopping 3,093 trees in Aarey Colony to make way for Mumbai’s Aqua Line ( Metro 3). For environmentalist Stalin Dayanand, this is not just a temporary problem.…

Notes from the field: Why Begur Lake is losing its waterbirds

71% of waterbirds at Begur Lake are declining. A visit to one of Bengaluru’s rapidly deteriorating lakes shows what's causing the collapse.

During the Open City biodiversity datajam held in December 2025, our group examined the ecological trends around Bengaluru’s lakes. Our analysis suggests a majority of waterbirds are declining across the city's lakes. Earlier, we addressed crucial questions on how migrant and resident waterbirds are surviving across 14 of Bengaluru’s lakes, how the shape of the lakes influence microhabitats, and how a scoring system can be used to record the decline in lake quality and bird populations. The last of our four-part series turns its attention to an individual site. As part of this study of waterbirds in 14 city lakes,…
