How to read the chart: the thick line is the current year, the thin one the median of the 1991-2020 reference period. The shaded band shows the normal range (25th–75th percentile), the dotted lines the maximum and minimum. Values above the band are unusually high for the season, below unusually low – but not an official warning.

Understanding the water level

What is the water level of Lake Sils? See the latest available level, its measurement time and source. Compare readings from the same station to understand the trend.

Reading in context

Putting Lake Sils's current level in context

The main station at Silsersee, Sils Baselgia reports a water level of 1,796.75 m a.s.l. at Sep 24, 2026, 1:10 AM. The series is provided by Bundesamt für Umwelt (BAFU). This value is the elevation of the water surface above the official height datum, not the water depth at the shore.

The median for the same calendar day is 1,796.78 m a.s.l.; the current value is 3 cm below it. The 1,796.75–1,796.81 m a.s.l. band contains the middle 50 percent of reference values from 1991-2020. Being outside it is less usual, but is not in itself a hazard level.

Comparison with the nearest valid readings gives 0 cm over 24 hours and -3 cm over seven days. These are net changes between two points in time; they prove neither a continuous rise or fall nor its cause.

Understanding Lake Sils

Lake Sils is the largest lake in the Upper Engadine and lies at nearly 1,800 metres above sea level.

This overview includes 2 monitoring stations for water level and water temperature. Not every station provides every measurement. Track changes at the same station, checking the timestamp, unit and source notes.

The curve shows recent level changes. A seasonal median, where available, compares the same time of year. Water can rise while remaining below that median: trend and comparison answer different questions. Neither replaces an official warning.

Measurement quality and sources

Data status

  • Measured — Recorded directly at a monitoring station.
  • Modelled — Computed by a scientific model (e.g. lake temperature from Alplakes), not measured on site.
  • Calculated — Derived from existing measurements, e.g. a balance or a change.
  • Archive image — Last archived image, not live.
