Yelahanka, Bengaluru, India
Yelahanka is the birth place of Nadaprabhu Kempekowda I, founder of City of Bengaluru. A fast growing suburb to Bengaluru with Aprox 3,00,000 people as per Census of 2011. Yelahanka’s growth has been manifold during the last decade with increased housing opportunities and employment due to increased domestication as the erstwhile township of Yelahanka was annexed to Bengaluru forming Brahut Bengaluru Municipal Corporation.
Glory of Yelahanka and Bengaluru.
The city of Bengaluru was attributed to “A City of 1000 Lakes” and the lakes of Bengaluru were designed Scientifically (Rajakalavas, wetlands etc) by the kings and administrators of Bengaluru and Suburban areas since 16th Century. In the 1960s the number of tanks and lakes was 280 and less than 80 in 1993 In the recent days, Bengaluru is left with hardly around 100 Lakes. Yelahanka remained as an outskirt of Bengaluru till 2008 and hence the lakes of Yelahanaka were grossly unaffected by Urbanization till recent years. However Bengaluru has recently witnessed disasters at Belandur and Varthur Lakes seen with several feet of Forth and catching fire.
Detrition of Lakes and Causes
With the urbanization in recent years Lakes of Yelahanaka (Puttenahalli Kere and Yelahanka Kere) are detreating due to
- Untreated Sewage flowing into the lakes as BWSSB has a defunct STP and recklessly leave the sewage into Puttenahalli Lake.
- Environmental pollution due upcoming 370 MW Gas based power plant at an Arial distance of 500 mts from Yelahanka Puttenahalli Lake which is declared as Bird Reserve. We fear destruction of flora and fauna of both Yelahanaka Lake and Puttenhalli Lake.
- Impact on biodiversity due to sewage inflow into Freshwater lake and also environmental pollution caused due to upcoming 370MW power plant.
- Destruction of Wetland connecting Puttenahalli Lake and Yelahanka Lake by making a culvert which has impacted the natural method of Water Purification.
- With the destruction of both the lakes, the lakes in the chain and wetlands will be adversely impacted.
In 2013, we the residents of Yelahanaka have decided to form a Trust in the name and style “Yelahanka Puttenahalli Lake and Bird Conservation Trust” to work towards rejuvenation of the lake and bird conservation.
In 2015 we initiated and achieved a success towards making Yelahanka Puttenahalli Lake a Bird reserve.
We at Puttenahalli Lake have taken technical support and consulting advise from eminent scientists from Indian Institute of Sciences (IISc, Bengaluru) and have worked in Tandem with Karnataka Forest Department towards rejuvenation of Lake.

- Provide possible support to protect the Environment by evaluating possibilities of reducing the impact of powerplant in a proximity to lakes.

2. Promoting citizens science and experiential Learning at Puttenahalli lake ‘Be a citizens Scientist for Day’. Period of project 5 years. Need to equip with equipment’s and resources. 3 Lakhs.
- To get citizen scientist involved in understanding the drivers of change in the blue and green spaces at Puttenahalli. Help monitor the variation in water quality in different seasons of the year
- Long time monitoring of water quality, bird survey, tree mapping, bee and butterfly surveys and understand the impact of seasonal variations
- To map the drivers of change in the catchment of water body and their relationship with quality
- To understand external weather events, ecosystem dynamics ( algal blooms, nutrient peaks ) relate to the direct surroundings and activities ( the level of human activity and population)
- To educate and spread awareness among citizens thus enabling them to conserve the environment
