A success story of lake rejuvenation

Today Kaikondrahalli Kere presents a totally different picture, with happy birds and happy visitors.

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 in the same year. The lake was completely drained and desilted. Trees were planted on the periphery and a walking track created. Even an island was formed in the middle of the lake. The whole project took about two years to complete.

Today Kaikondrahalli Kere presents a totally different picture. It has water even though Bangalore has had a dry spell last year. And the lake is teeming with birdlife! One can see around 300 spotbill ducks scattered across the lake. Darters which were not seen before are regularly seen. There are plenty of Egrets -small and median, Herons – pond, grey and purple. Indian cormorants can be seen perched on the trees. Purple moorhens roam the marshy areas surrounding the lake.

The island, created during the rejuvenation, is full of vegetation, providing nesting places for birds. During winters quite a few migrants; Graganeys and Common Pochards have been seen. Painted Snipes have also been occasionally spotted. Marsh harriers are a common sight along with two other raptors – Brahminy and Pariah Kites. Three species of Kingfisher – White-throated, Pied and Small Blue, are residents of the lake. Little Grebes and Coots too are a common sight along with Redwattled lapwings. If one is lucky, the Paradise Flycatcher too can be spotted. A total of more than 55 species have been recorded from in and around the lake. Prior to rejuvenation this number was around 40.

The bird population and diversity has gone up in spite of increase in the number of walkers and the frenzied construction happening around the lake. The healthy bird population indicates that the lake has an abundance of aquatic life essential for sustaining birdlife.

In the past the lakes were "privatised" with disastrous results. The current state of the Agara lake bears testimony to the fact that privatisation is not the answer. One can only hope that the Kaikondrahalli Lake rejuvenation model is applied to other lakes across Bangalore before it is too late. This model rejuvenates lakes, which not only help in supporting birdlife but also provide recreational areas for the local neighbourhoods. The Lake Development Authority should take lessons from Kaikondrahalli Kere rejuvenation case and save lakes in Bangalore, which are in a complete state of neglect.⊕

    Sad to see sewage mixing with the lake water now… Hope it doesn’t affect the fishes too much.

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,…

Bengaluru lakes are changing, and birds are paying the price

From disappearing reedbeds to altered shores, here is why some of the city's lakes are thriving while others face ecological collapse.

While bird detection trends over the years clearly point to the decline of Bengaluru’s shoreline and vegetated-edge habitats, numbers alone tell only part of the story. In Part 3 of this four-part series on the state of the city's waterbirds, we have used a scoring system to understand how stressed the lakes and the microhabitats within the lake are, based on the bird diversity they support. We explore how lake shape, permanent inundation and shifts in citizen-led management might explain why some lakes may thrive as wetlands while others collapse.  For instance, at Kasavanahalli, the Pied Kingfisher and the Coot…
