1957
Built
As the 2018 lake survey records it
1980
On the survey map
1984-2021
Held water most years
Water in 8% of all satellite passes, 1984-2024
0% of its water area has since gone dry; 5% is new water
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
6% encroached, clean, 20.5 acres surveyed
2025-2026
Mostly floating weed after the monsoon; mostly dry or built in the dry season
After monsoon, Oct 2025 to Dec 2025
- 1% open water
- 92% floating weed
- 7% dry or built
Dry season, Mar 2026 to May 2026
- 3% open water
- 0% floating weed
- 97% dry or built
