  3. 1984-2021

    Held water most years

    Water in 11% of all satellite passes, 1984-2024

    4% of its water area has since gone dry; 22% 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

  4. 2017-2025

    Mostly water in most years

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