Through the years

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

The records listed below, drawn on one line from 1945 to 2026.

  1. 1945

    On the survey map

    See source

  2. 1955

    On the U.S. Army map

    Compiled from Survey of India maps of 1945-46

    See source

  3. 1980

    On the survey map

    See source

  4. 1984-2021

    Held water most years

    Water in 16% of all satellite passes, 1984-2024

    2% of its water area has since gone dry; 21% 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

  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 plants or weed in most years

    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

  7. 2025-2026

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

    After monsoon, Oct 2025 to Dec 2025

    • 25% open water
    • 35% floating weed
    • 40% dry or built

    Dry season, Mar 2026 to May 2026
