Some locals have observed one or two dead fish in the lake. Although it cannot be attributed to a mass fish kill incident, it has raised some concerns. During the water quality check conducted by the Action Aid Association, the DO levels on January 9 were found to be about 2.97 mg/L. The ideal levels should typically range between 6.8-8.5 mg/L.
As per the report filed with the help of inputs from 394 respondents, 46% of respondents lived within less than a 1-km radius of the lake, 43% lived within the neighbourhood, 9% lived further than 1 km, and 2% were not Bengaluru residents.
The survey, spearheaded by J N Prasad, a dedicated Bird Watcher, was carried out on multiple dates, specifically July 30, August 4, and August 6, 2023, with a dual session of birdwatching taking place in the mornings and evenings. A total of 48 distinct bird species were observed during this comprehensive survey.

The rejuvenation of Doddakallasandra Lake can be traced back to Justice NK Patil’s report commissioned by the Karnataka government in 2012. The report aimed to breathe new life into water and ecological security throughout the state. Covering an expansive 21.16 acres, the lake’s restoration was undertaken by the BBMP a few years ago, with residents actively participating in improving its conditions.
