Putting Lake Zug's current level in context
The main station at Zug reports a water level of 413.18 m a.s.l. at Nov 7, 2026, 1:10 PM. 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.
Lake Zug: what is a normal water level?
The median for the same calendar day is 413.44 m a.s.l.; the current value is 26 cm below it. The 413.35–413.55 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.
How is the reference level determined?
The reference comes from FOEN daily statistics for this calendar day. The seasonal median varies throughout the year and is not a fixed target level. The middle 50% is the range between the 25th and 75th percentiles, not a safety limit. The 30-day comparison describes only the recent development.
Comparison with the nearest valid readings gives 0 cm over 24 hours and -2 cm over seven days. These are net changes between two points in time; they prove neither a continuous rise or fall nor its cause.
