Held water most years
Water in 10% of all satellite passes, 1984-2024
31% of its water area has since gone dry; 0% is new water
Floating weed looks like dry land to this record, so a weed-covered year can read as dry
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
