Through the years

Nothing on record for 1924 to 1979 and 1981 to 1983.

The records listed below, drawn on one line from 1923 to 2026.

  1. 1923

    Built

    As the 2018 lake survey records it

    See source

  2. 1980

    On the survey map

    See source

  3. 1984-2021

    Held water in 11 of 38 years

    Water in 5% of all satellite passes, 1984-2024

    0% of its water area has since gone dry; 46% is new water

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

    See sourceSee source

  4. 2017-2018

    In the water bodies census, not marked as encroached

    This census's status marks are often wrong

    See source

  5. 2017-2025

    Mostly water 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

    5% encroached, sewage, 13.1 acres surveyed

    Tested by the state board in 34 months, most often fit only for wildlife and fish

    Aug 2023 to Jul 2026

    See every testSee source

  8. 2025-2026

    Mostly open water after the monsoon; mostly floating weed in the dry season

    After monsoon, Oct 2025 to Dec 2025

    • 81% open water
    • 10% floating weed
    • 10% dry or built

    Dry season, Mar 2026 to May 2026

    • 0% open water
