Through the years

Nothing on record for 1904 to 1944, 1946 to 1979 and 1981 to 1983.

The records listed below, drawn on one line from 1903 to 2026.

  2. 1945

  3. 1980

  4. 1984-2021

    Held water in 21 of 34 years

    Water in 7% of all satellite passes, 1984-2024

    15% of its water area has since gone dry; 0% 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

  5. 2017-2025

    Mostly plants or weed in most years

    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

  6. 2018

    Still there in the 2018 lake survey

    0.1% encroached, polluted, 13.0 acres surveyed

  7. 2025-2026

    Tested by the state board in 18 months, most often fit only for wildlife and fish

    Feb 2025 to Jul 2026

  8. 2025-2026

    Mostly dry or built after the monsoon and in the dry season

    After monsoon, Oct 2025 to Dec 2025

    • 0% open water
    • 41% floating weed
    • 59% dry or built

    Dry season, Mar 2026 to May 2026

    • 0% open water
    • 0% floating weed
    • 100% dry or built
