Through the years

Nothing on record for 1916 to 1954, 1956 to 1972 and 1974 to 1983.

The records listed below, drawn on one line from 1915 to 2026.

  1. 1915

    On the survey map

    See source

  2. 1955

    On the U.S. Army map

    Compiled from Survey of India maps of 1945-46

  3. 1973

    On the survey map

    See source

  4. 1984-2021

    Held water most years

    Water in 10% of all satellite passes, 1984-2024

    42% of its water area has since gone dry; 0% 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

  5. 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

  6. 2023-2026

    Tested by the state board in 33 months, most often fit only for wildlife and fish

    Oct 2023 to Jul 2026

  7. 2025-2026

    Mostly floating weed after the monsoon; mostly dry or built in the dry season

    After monsoon, Oct 2025 to Dec 2025
