Reference: 30 available daily means from the last 30 complete days (Coordinated Universal Time, UTC), compared with the current individual value. Being close to the median does not describe the spread of values. Gaps can affect daily means. This is neither a seasonal normal nor an official danger level.

Discharge over the last 30 days

One line per station. Differences are not a direct inflow balance: measurement times, travel times, storage, withdrawals and tributaries can affect the values.

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.

Water knowledge

Understanding Thur

Thur: this overview puts the available stations and measurements in context. The exact location matters, not just the water body's name.

This overview includes 25 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.

Discharge in m³/s is a volume per second, not the speed of the current. Station comparisons must account for location, measurement time and water travel time. A higher reading is neither automatically a flood warning nor an indication that the river is navigable.
