A calm view of the water
Swiss lakes, rivers and local monitoring stations in one place. Deliberately save your favourites and follow changes since your last visit in your personal overview.
Level charts for 24 hours, 7 days and 30 days, with seasonal comparisons. At Lake Constance, Konstanz, Romanshorn and Berlingen help explain the upper and lower lake. Different height references remain clearly labelled.
Choose the reading, threshold, repeat pattern and end date. Seepegel notifies you after a confirmed crossing and avoids unnecessary back-and-forth alerts.
Choose a main and a second reading: level, water temperature, air temperature, wind or 24-hour rain. Measurement times and available sources remain visible.
Compare up to three lakes side by side. Share levels and water temperatures as images for a post or story, with a preview before sending.
