See it on the mapThrough the years
Nothing on record for 1907 to 1944, 1946 to 1954, 1956 to 1979 and 1981 to 1983.
1906
Built
As the 2018 lake survey records it
1945
On the survey map
1955
On the U.S. Army map
Compiled from Survey of India maps of 1945-46
1980
On the survey map
1984-2021
Held water most years
Water in 28% of all satellite passes, 1984-2024
19% of its water area has since gone dry; 0% is new water
4 years not counted: the satellite saw under half the lake
Floating weed looks like dry land to this record, so a weed-covered year can read as dry
2017-2018
In the water bodies census, not marked as encroached
This census's status marks are often wrong
2017-2025
No one cover holds over half of it in most years
About three in four of these readings are right, so trust what holds for several years
2018
Still there in the 2018 lake survey
10% encroached, polluted, 130 acres surveyed
2023-2026
Tested by the state board in 13 months, most often fit only for wildlife and fish
Dec 2023 to Jul 2026
2024
On the state's list of Bengaluru lakes, looked after by BBMP
2025-2026
Mostly floating weed after the monsoon; mostly dry or built in the dry season
After monsoon, Oct 2025 to Dec 2025
- 3% open water
- 72% floating weed
- 25% dry or built
Dry season, Mar 2026 to May 2026
- 0.1% open water
- 34% floating weed
- 66% 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.
