53% of the lakeSatellite, 2021. The 2018 survey found 30% encroached.

Through the years

Nothing on record for 1870 to 1954, 1956 to 1979 and 1981 to 1983.

The records listed below, drawn on one line from 1869 to 2026.

  1. 1869

    Built

    As the 2018 lake survey records it

    See source

  2. 1955

    Not 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 in 22 of 38 years

    Water in 15% of all satellite passes, 1984-2024

    3% of its water area has since gone dry; 10% is new water

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

    See sourceSee source

  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 built on or bare every year

    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

    30% encroached, polluted, 18.1 acres surveyed

    See source

  8. 2023-2026

    Tested by the state board in 36 months, most often fit only for wildlife and fish
