Through the years

Nothing on record for 1921 to 1926, 1928 to 1954, 1956 to 1977 and 1979 to 1983.

The records listed below, drawn on one line from 1920 to 2026.

  1. 1920

    Built

    As the 2018 lake survey records it

    See source

  2. 1927

    On the survey map

    See source

  3. 1955

    On the U.S. Army map

    Compiled from Survey of India maps of 1945-46

    See source

  4. 1978

    On the survey map

    See source

  5. 1984-2021

    Held water most years

    Water in 10% of all satellite passes, 1984-2024

    50% of its water area has since gone dry; 0.8% 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

    See sourceSee source

  6. 2017-2018

    In the water bodies census, not marked as encroached

    This census's status marks are often wrong

    See source

  7. 2017-2025

    Mostly plants or weed every year

    Floating weed shows as crops or grass here, not as water

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

    See source

  8. 2018

    Still there in the 2018 lake survey

    0.0% encroached, polluted, 188 acres surveyed

    See source

  9. 2023-2026

    Tested by the state board in 35 months, most often fit only for irrigation

    Jul 2023 to Jul 2026

    See every testSee source

  10. 2025-2026

    Mostly floating weed after the monsoon; mostly open water in the dry season

    After monsoon, Oct 2025 to Dec 2025

    • 16% open water
    • 64% floating weed
    • 20% dry or built

    Dry season, Mar 2026 to May 2026

    • 52% open water
    • 5% floating weed
    • 44% dry or built
