River Water Level, Discharge and Water Temperature History at German Gauging Stations — Daily Archive (PEGELONLINE)

Daily mean, minimum and maximum of the water level (cm), discharge (m³/s) or water temperature (°C) at any PEGELONLINE gauging station on German federal waterways. PEGELONLINE itself only keeps 30 days; this is our own archive, starting late September 2026 and growing every day.
