  4. 1984-2021

    Held water until 2016

    Water in 5% of all satellite passes, 1984-2024

    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

  5. 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

    20% encroached, polluted, 28.3 acres surveyed

    See source

    Mostly floating weed after the monsoon and in the dry season

    After monsoon, Oct 2025 to Dec 2025

    • 0% open water
    • 90% floating weed
    • 10% dry or built

    Dry season, Mar 2026 to May 2026
