See it on the mapThrough the years
Nothing on record for 1921 to 1926, 1928 to 1954, 1956 to 1977 and 1979 to 1983.
1920
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 12% of all satellite passes, 1984-2024
3% of its water area has since gone dry; 5% 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
1986
Listed among green belt tanks by the Lakshman Rau committee
Printed as Cheemasandra tank, tank 593
13.2 ha, as printed in the 1986 report
Among the tanks between Bellary Road and Madras Road, Hoskote taluk
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
3% encroached, muddy and polluted, 26.5 acres surveyed
2025-2026
Tested by the state board in 15 months, most often fit only for irrigation
May 2025 to Jul 2026
2025-2026
Mostly floating weed after the monsoon and in the dry season
After monsoon, Oct 2025 to Dec 2025
- 0% open water
- 87% floating weed
- 13% dry or built
Dry season, Mar 2026 to May 2026
- 0% open water
- 62% floating weed
- 38% 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 irrigation, cooling and waste disposal. Class E on the state board’s scale from A, the cleanest, to E.
