Through the years

Nothing on record for 1915 to 1972 and 1974 to 1983.

The records listed below, drawn on one line from 1914 to 2026.

  1. 1914

    Not on the survey map

    See source

  2. 1973

    Not on the survey map

    See source

  3. 1984-2021

    Held water in 10 of 38 years

    Water in 0.6% of all satellite passes, 1984-2024

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

  4. 1998

    Built

    As the 2018 lake survey records it

    See source

  5. 2017-2018

    In the water bodies census, not marked as encroached

    This census's status marks are often wrong

    See source

  6. 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

    Polluted, 4.75 acres surveyed

    See source

  8. 2025-2026
