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.

Water knowledge

Understanding Glatt

Glatt is an ambiguous name: Zurich's Glatt leaves Greifensee, but there is also a Glatt station at Herisau. The Greifensee outlet weir influences water release. Check the municipality and map position before assigning a Glatt curve to a particular reach.

This overview includes 14 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. Related waters in this overview: Lake Greifen.

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.
