See it on the mapThrough the years
Nothing on record for 1967 to 1979 and 1981 to 1983.
1966
Built
As the 2018 lake survey records it
1980
Not on the survey map
1984-2021
Held water most years
Water in 7% of all satellite passes, 1984-2024
0% of its water area has since gone dry; 39% is new water
Floating weed looks like dry land to this record, so a weed-covered year can read as dry
2000
Restored
2017-2018
In the water bodies census, not marked as encroached
This census's status marks are often wrong
2017-2025
Mostly built on or bare every year
About three in four of these readings are right, so trust what holds for several years
2018
Still there in the 2018 lake survey
Polluted, 6.17 acres surveyed
2024
On the state's list of Bengaluru lakes, looked after by BBMP
2025-2026
Tested by the state board in 16 months, most often fit only for wildlife and fish
Apr 2025 to Jul 2026
2025-2026
Part dry or built, part floating weed after the monsoon; part open water, part floating weed in the dry season
After monsoon, Oct 2025 to Dec 2025
- 22% open water
- 32% floating weed
- 46% dry or built
Dry season, Mar 2026 to May 2026
- 42% open water
- 41% floating weed
- 17% dry or built
How big it is
The records disagree on its size, so each measure is shown.
How clean the water is
Fit only for wildlife and fisheries. Class D on the state board’s scale from A, the cleanest, to E.
