Through the years

Nothing on record for 1870 to 1944, 1946 to 1954, 1956 to 1979 and 1981 to 1983.

The records listed below, drawn on one line from 1869 to 2026.
  1. 1869

    Built

    As the 2018 lake survey records it

  2. 1945

    On the survey map

  3. 1955

    Not on the U.S. Army map

    Compiled from Survey of India maps of 1945-46

  4. 1980

    On the survey map

  5. 1984-2021

    Held water most years

    Water in 21% of all satellite passes, 1984-2024

    5% of its water area has since gone dry; 28% 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

  6. 2017-2018

    In the water bodies census, not marked as encroached

    This census's status marks are often wrong

  7. 2017-2025

    Mostly water every year

    About three in four of these readings are right, so trust what holds for several years

  8. 2018

    Still there in the 2018 lake survey

    0.5% encroached, clean, 28.6 acres surveyed

  9. 2023-2026

    Tested by the state board in 36 months, most often fit only for irrigation

    Jul 2023 to Jul 2026

  10. 2024

    On the state's list of Bengaluru lakes, looked after by BBMP

  11. 2025-2026

    Mostly floating weed after the monsoon and in the dry season

    After monsoon, Oct 2025 to Dec 2025

    • 0% open water
    • 93% floating weed
    • 7% dry or built

    Dry season, Mar 2026 to May 2026

    • 0.1% open water
    • 79% floating weed
    • 21% dry or built

How big it is

The records disagree on its size, so each measure is shown.
