See it on the mapThrough the years
Nothing on record for 1905 to 1926, 1928 to 1954, 1956 to 1977 and 1979 to 1983.
1904
Built
As the 2018 lake survey records it
1927
On the survey map
1955
On the U.S. Army map
Compiled from Survey of India maps of 1945-46
1978
On the survey map
1984-2021
Held water most years
Water in 17% of all satellite passes, 1984-2024
0% of its water area has since gone dry; 75% is new water
6 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
Mostly water 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
4% encroached, clean, 51.9 acres surveyed
2024
On the state's list of Bengaluru lakes, looked after by BBMP
2025-2026
Mostly open water after the monsoon and in the dry season
After monsoon, Oct 2025 to Dec 2025
- 82% open water
- 16% floating weed
- 3% dry or built
Dry season, Mar 2026 to May 2026
