Through the years

Nothing on record for 1928 to 1954, 1956 to 1958, 1960 to 1977 and 1979 to 1983.

The records listed below, drawn on one line from 1927 to 2026.

  1. 1927

  2. 1955

    On the U.S. Army map

    Compiled from Survey of India maps of 1945-46

  4. 1978

    On the survey map

  5. 1984-2021

    Held water most years

    Water in 12% of all satellite passes, 1984-2024

    0.9% of its water area has since gone dry; 7% is new water

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

  6. 2016

    Restored

  7. 2017-2018

    In the water bodies census, not marked as encroached

    This census's status marks are often wrong

  8. 2017-2025

    Mostly water in most years

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