Through the years

Nothing on record for 1905 to 1926, 1928 to 1954, 1956 to 1977 and 1979 to 1983.

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

  1. 1904

    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 until 2017

    Water in 2% of all satellite passes, 1984-2024

    0% of its water area has since gone dry; 18% is new water

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

    See sourceSee source

  6. 2013

    Restored

    See source

  7. 2017-2018

    In the water bodies census, not marked as encroached

    This census's status marks are often wrong

    See source

  8. 2017-2025

    Mostly built on or bare from 2022

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

    See source

  9. 2018

    Still there in the 2018 lake survey

    20% encroached, sewage, 21.7 acres surveyed
