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.

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
- A Sentinel-3 or Sentinel-6 radar track crosses this reservoir, so a level continues even if SWOT stops.
- If SWOT stops
- A Sentinel-3 or Sentinel-6 nadir track crosses this reservoir and it is at or above 20 km2, the size at which the licensed nadir level is measurement-backed (experiments 34, 46, 47: 21 of 21 fresh reservoirs where SWOT passes, median error 0.13 m). Without SWOT an elevation series continues at about half the cadence.
