  • Are nature/ bird photographers allowed? Do you charge fees for the camera?
    Nature/ bird photographers are most welcome. No fee is charged for the camera. We invite you to share your photographs with us.
  • Can we immerse idols, dispose puja materials in the water?
    No. These will pollute the water gradually killing the fish and other living organisms. Flowers are typically cultivated with pesticides and fertilizers. The residue of these in the flowers and leaves mix in the water making it toxic. Further, when the flowers and leaves rot and decompose, they use up vital nutrients from the water. The plastic, cloth, even the string of garland can trap a bird and cause it to die. Puttenahalli Lake is not a designated lake for idol immersion. However, we do provide a bin filled with water for this purpose. The idol needs to be necessarily small, made of clay and NOT painted/ PoP idols.

  • How big should the lake group/trust be?
    Many will join enthusiastically at the beginning only to drop off along the way. It doesn’t matter because decision making will be easier and faster if the core group is small.
  • Under which Government department is Puttenahalli Lake?
    The Lakes division of the municipality, Bruhat Bengaluru Mahanagara Palike (BBMP)
  • How do you get birds to the lake?
    They come on their own. We have: a) Planted bird and butterfly attracting plants around our lake. b) Planted tree stumps and trunks in the water and at the edge for birds to perch. c) Vegetation patches and floating islands provide safe nesting places and food for birds. d) Introduced different types of fishes. All these efforts are to get more and different species of birds to our lake.
  • How do you get the community involved?
    Don’t worry about getting everyone on board. The number of people who engage or are interested in civic matters is woefully small and growing smaller. Nevertheless, go to the community, inform them of your intent to save the lake, send them updates to stimulate and foster their interest, involve them in activities at the lake – tree plantation and story-telling sessions are invariably big draws. Keep sharing your passion loudly and clearly. More people will support the cause even if, at first, they don’t come forward to join you.
  • How do you stop sewage inflow?
    We maintain a close watch on the inlets and inform the ward office of the Bengaluru Water Supply and Sewerage Board (BWSSB) immediately if we spot sewage trickling in. Typically, they use a Jetting Machine to remove the blockage in the underground drain (UGD). If the problem persists or aggravates, we escalate the issue to the head office and don’t stop till the authorities stop sewage influx.
  • Why is aeration important in a waterbody?
    Lakes and ponds are stagnant waterbodies. If left alone, the oxygen level will drop and cause fish to die. A thick biofilm will form over the surface of the water causing it to deteriorate even more and make it a perfect breeding ground for mosquitoes and algal bloom. An aerator will prevent stagnation by circulating the water and increasing dissolved oxygen level.
  • How do you control invasive aquatic weeds from covering the lake?
    When the aquatic plants covered the entire lake, we hired fishermen to remove them. As the quality of the water improved, their growth rate reduced. We try to maintain a balance between the aquatic vegetation (useful for birds) and the surface exposed to the sun (to improve the water quality).
  • What do you do if government officials refuse to act even after innumerable requests?
    When repeatedly stonewalled and issues remain unresolved for long, we escalate the problem, inform the neighbourhood and publicise the state of affairs through the press.
  • How do I save a lake in my locality?
    Wanting to save the lake is the winning half the battle. Hold on to this while you instil the same concern in your community. It requires considerable perseverance and dedication but the outcome, the marvellous sight of the thriving lake will be worth it all. “Prepare to be alone at times, and to endure failure. Persist! The world needs all you can give.” ― E.O. Wilson When public interest in reviving Bengaluru lakes increased, PNLIT Trustee Arathi Manay wrote this article: How to revive your neighbourhood lake which remains relevant for any city.
