Water level today
The satellite measures the height of the water surface above sea level. Every figure carries how old it is, because the age of a level is that level’s error.

96 of 100
80 percent band. Out-of-fold coverage 0.805 [0.759, 0.848] at 176 gauged reservoirs; weakest held-out country India and other at 0.511, so the band is calibrated where the labels are dense and not everywhere. Measured on archive-confirmed observations.
Where the level is heading
A three-to-four week outlook, with the range the level falls in 80 times out of 100. It widens with distance, because further ahead is less certain.

How this record was made
Every number on this page was computed once, under a frozen specification, from the sources listed here. The page computes nothing.
- Validation
- Checked against held-out gauges in this reservoir’s own climate and size group.
- Continuity
- No nadir track crosses it, so without SWOT only the surface area survives, not the level.
- If SWOT stops
- No Sentinel-3 or Sentinel-6 track crosses this reservoir. Without SWOT only the water area survives; no elevation series continues.
