Through the years

Nothing on record for 1946 to 1954, 1957 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

    Not on the U.S. Army map

    Compiled from Survey of India maps of 1945-46

    See source

  3. 1956

    Built

    As the 2018 lake survey records it

  4. 1980

    On the survey map

    See source

  5. 1984-2021

    Held water until 2004

    Water in 0.1% of all satellite passes, 1984-2024

    0% of its water area has since gone dry; 0.6% is new water

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

  6. 1986

    Listed among green belt tanks by the Lakshman Rau committee

    Printed as Junnasandra tank, tank 220

    0.25 ha, as printed in the 1986 report

    Among the tanks between Madras Road and Hosur Road, Bangalore South taluk

  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 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

    Still there in the 2018 lake survey

    Green water, 24.8 acres surveyed
