Through the years

Nothing on record for 1907 to 1944, 1946 to 1954, 1956 to 1979 and 1981 to 1983.

The records listed below, drawn on one line from 1906 to 2026.
  1. 1906

    Built

    As the 2018 lake survey records it

  2. 1945

    On the survey map

  3. 1955

    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 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

  6. 2017-2018

    In the water bodies census, not marked as encroached

    This census's status marks are often wrong

  7. 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

  8. 2018

    Still there in the 2018 lake survey

    10% encroached, polluted, 130 acres surveyed

  9. 2023-2026

    Tested by the state board in 13 months, most often fit only for wildlife and fish

    Dec 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; 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
