Median of available daily means: 7.3 m³/s · 30 days in the comparison window.

The current individual value is compared with available daily means from the last 30 completed UTC calendar days. Min. and max. refer to daily means, not individual peaks. A day counts when values exist; gaps can affect its mean. For model series, this compares model values. “High” refers to this short window, not an official danger level or a seasonal normal.

Over the past 24 hours the value ranged between 5.0 m³/s and 7.5 m³/s and fell by 1.5 m³/s.

Based on 145 available values from Sep 21, 2026, 3:50 AM to Sep 22, 2026, 3:50 AM (Swiss local time). The range describes stored values, not necessarily every peak that occurred.

Understanding readings at Rhône, Gletsch (inflow, headwater)

This station is linked to the Lake Geneva overview. Its name identifies the location: a station on an inflow or outflow does not necessarily describe the lake’s water level or temperature.

Discharge in m³/s is the volume passing a cross-section each second. It is neither current speed nor water depth. Compare the same station over time; the difference between two stations alone is not a measurement of intervening inflow.

Check the time and source first, then the chart and unit. Missing or disrupted readings cannot support a reliable current assessment. A short comparison describes recent changes, not flood probability. Follow official warnings and local instructions for safety decisions.
