Sihl, Zürich (inflow) – Discharge
This station shows Discharge in an inflow to Lake Zurich. It describes the incoming river, not conditions in the lake itself.
Current discharge
2.0m³/s↓
Measurement time:
Current FOEN data are unchecked raw data and may be corrected later. A recent measurement time does not mean that a value has been validated. FOEN data quality
Current context
Largely stable over the last 24 hours. 0.9 m³/s lower than 7 days ago.
What does this change mean?
“Largely stable” means the flow has changed by less than 5% from about 24 hours earlier. If the comparison value is zero, any increase counts as a change.
We compare values at the same station at two points in time. If no suitably timed comparison value exists, we omit that statement. An unchanged value does not mean a seasonal normal or an all-clear. Changes below the displayed precision are also described as stable.
Past 30 days at a glance
LowMedian of available daily means: 2.9 m³/s · 30 days in the comparison window.
The current individual value is compared with available daily means from the last 30 complete days, using Coordinated Universal Time (UTC) for day boundaries. 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 1.9 m³/s and 2.1 m³/s and stayed largely stable.
Based on 144 available values from Nov 6, 2026, 2:00 PM to Nov 7, 2026, 2:00 PM (Swiss local time). The range describes stored values, not necessarily every peak that occurred.
The forecast value is expected to rise by about 3.7 m³/s across the 6 displayed forecast days.
Forecast
Source: FOEN forecast- Median
- Min./Max.
- Measured
The line shows the median of the FOEN model forecasts at each timestamp; the band shows their minimum and maximum. Daily cards average the available hourly medians, which is not a daily median. A wider band means greater spread between model paths, not guaranteed upper or lower limits. Partial days may contain fewer forecast values.
Understanding readings at Sihl, Zürich (inflow)
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.
