Through the years

Nothing on record for 1905 to 1944, 1946 to 1954, 1956 to 1979 and 1981 to 1983.

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

  1. 1904

    Built

    As the 2018 lake survey records it

  2. 1945

  3. 1955

    Not on the U.S. Army map

  4. 1980

    On the survey map

    See source

  5. 1984-2021

    Held water most years

    Water in 10% of all satellite passes, 1984-2024

    9% of its water area has since gone dry; 26% 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

    See sourceSee source

  6. 2017-2025

    No one cover holds over half of it in most years

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

  7. 2018

    Still there in the 2018 lake survey

    10% encroached, clean and polluted, 21.4 acres surveyed

    See source

  8. 2023-2026

    Tested by the state board in 25 months, most often fit only for wildlife and fish

    Aug 2023 to Jul 2026

    See every testSee source

  9. 2025-2026

    Mostly floating weed after the monsoon and in the dry season

    After monsoon, Oct 2025 to Dec 2025

    • 0% open water
    • 98% floating weed
    • 2% dry or built

    Dry season, Mar 2026 to May 2026

    • 0.5% open water

Wikipedia

Lakes and tanks in the metropolitan area of Greater Bangalore and the district of Bangalore Urban are reservoirs of varying sizes constructed over a number of centuries by various empires and dynasties for rainwater harvesting. Historically, these reservoirs were primarily either irrigation tanks or for the water supply, with secondary uses such as bathing and washing. The need for creating and sustaining these man-made dammed freshwater reservoirs was created by the absence of a major river nearby coupled with a growing settlement. As Bangalore grew from a small settlement into a city, both of the primary historical uses of the tanks changed. Agricultural land witnessed urbanization and alternate sources of water were provisioned, such as through borewells, piped reservoir water and later river water from further away.
