Through the years

Nothing on record for 1946 to 1956, 1958 to 1979 and 1981 to 1983.

The records listed below, drawn on one line from 1945 to 2026.

  1. 1945

    On the survey map

    See source

  2. 1957

    Built

    As the 2018 lake survey records it

    See source

  3. 1980

    Not on the survey map

    See source

  4. 1984-2021

    Held water most years

    Water in 13% of all satellite passes, 1984-2024

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

    Floating weed looks like dry land to this record, so a weed-covered year can read as dry

    See sourceSee source

  5. 2009

    Restored

    See source

  6. 2017-2018

    In the water bodies census, not marked as encroached

    This census's status marks are often wrong

    See source

  7. 2017-2025

    Mostly water every year

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

  8. 2018

    Still there in the 2018 lake survey

    8% encroached, clean, 11.8 acres surveyed
