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.

  1. 1903

    Built

    As the 2018 lake survey records it

    See source

  2. 1945

    On the survey map

    See source

  3. 1980

    Not on the survey map

    See source

  4. 1984-2021

    Held water most years

    Water in 24% of all satellite passes, 1984-2024

    0% of its water area has since gone dry; 13% 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

    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

    See source

  6. 2018

    Still there in the 2018 lake survey

    Polluted, 10.6 acres surveyed

    See source

  7. 2023-2026
