Through the years

Nothing on record for 1905 to 1944, 1946 to 1979 and 1981 to 1983.

The records listed below, drawn on one line from 1904 to 2026.

  1. 1904

    Built

    As the 2018 lake survey records it

  2. 1945

  3. 1980

    On the survey map

  4. 1984-2021

    Held water most years

    Water in 5% of all satellite passes, 1984-2024

    13% of its water area has since gone dry; 13% is new water

    Floating weed looks like dry land to this record, so a weed-covered year can read as dry

  5. 2017-2018

    In the water bodies census, not marked as encroached

    This census's status marks are often wrong

    See source

  6. 2017-2025

    Mostly water in most years

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

    See source

  7. 2018

    Still there in the 2018 lake survey

    3% encroached, clean, 14.9 acres surveyed

    See source

  8. 2025-2026

    Part floating weed, part open water after the monsoon; mostly dry or built in the dry season

    After monsoon, Oct 2025 to Dec 2025

    • 28% open water
    • 46% floating weed
    • 26% dry or built

    Dry season, Mar 2026 to May 2026

    • 30% open water
    • 5% floating weed
    • 65% dry or built
