Reading in context

Putting Lake Pfäffikon's current level in context

The main station at Pfäffikon reports a water level of 536.50 m a.s.l. at Sep 24, 2026, 1:10 AM. The series is provided by Kanton Zürich (AWEL) – HydroPro. This value is the elevation of the water surface above the official height datum, not the water depth at the shore.

Comparison with the nearest valid readings gives -1 cm over 24 hours and -5 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 Pfäffikon

Lake Pfäffikon lies in the Zurich Oberland between Pfäffikon, Seegräben and Wetzikon.

This overview includes 4 monitoring stations for water level, discharge, 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.
