12th Nov 2012 Dr S. Subramanya Recently, Yelahanka Lake was developed by BBMP. For once, instead of dredging the lake into an uniform depth, the lake-bed was scrapped to have a gradual slope towards the main bund. Thanks to the recent cyclonic storms in the Bay, the lake is 3/4th full with about waist deep water near the bund. Although the water is near clear, there is still some sewage mixed-up in it (mainly due to the inflow from the Puttenahalli Lake in the upstream). The overall effect of this is quite evident in the diversity of birds it supports. The lake looks like a hemi-marsh with about 1/3 of the waterspread area covered with emergent vegetation (see the first image & don't miss the clearness of water). Here is the list of bird species seen at Yelahanka Lake this morning at 8.00-9.00am: Egrets & Herons: 1. Pond heron 2. Cattle Egret 3. Little Egret 4. Median Egret 5. Large Egret 6. Grey Heron 7.
