Through the years

Nothing on record for 1905 to 1926, 1928 to 1954, 1956 to 1977 and 1979 to 1983.

The records listed below, drawn on one line from 1904 to 2026.

  5. 1984-2021

    Held water in 23 of 38 years

    Water in 9% of all satellite passes, 1984-2024

    5% of its water area has since gone dry; 31% is new water

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

    Restored

  7. 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

    Still there in the 2018 lake survey

    Polluted, 74.8 acres surveyed

    See source
