Through the years

Nothing on record for 1915 to 1926, 1928 to 1954, 1956 to 1977 and 1979 to 1983.

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

  1. 1914

    Built

    As the 2018 lake survey records it

  2. 1927

  3. 1955

    On the U.S. Army map

  4. 1978

    On the survey map

    See source

  5. 1984-2021

    Held water most years

    Water in 12% of all satellite passes, 1984-2024

    12% of its water area has since gone dry; 9% 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

  6. 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

  7. 2018

    Still there in the 2018 lake survey

    10% encroached, muddy, 85.1 acres surveyed

    See source

  8. 2025-2026

    Part floating weed, part open water after the monsoon; mostly dry or built in the dry season

    After monsoon, Oct 2025 to Dec 2025

    • 31% open water
    • 39% floating weed
    • 29% dry or built

    Dry season, Mar 2026 to May 2026

    • 13% open water
    • 3% floating weed
    • 85% dry or built
