Pegel

Search stations in Germany and its neighbouring countries — river gauges, groundwater wells, reservoirs, coastal gauges — by name or water body, optionally filtered by region (a German federal state or a country code). latestValue is given in the station's unit. Every result names the data provider in sourceNotice (search and flood situation: sourceNotices, keyed by sourceNoticeId); show that notice with any value, class or forecast you pass on, and the licence terms of the API require it.

Current flood situation: stations with an active LHP flood class (1 small … 4 very large), optionally per federal state. Every result names the data provider in sourceNotice (search and flood situation: sourceNotices, keyed by sourceNoticeId); show that notice with any value, class or forecast you pass on, and the licence terms of the API require it.

Master data of one station: measurement type, current value with its unit, thresholds (MNW/MHW, alert marks, as stored valueCentimeters), flood class, coordinates. Every result names the data provider in sourceNotice (search and flood situation: sourceNotices, keyed by sourceNoticeId); show that notice with any value, class or forecast you pass on, and the licence terms of the API require it.

Time series for a station (downsampled to ≤200 points; history depth on this tier: last 90 days, default last 7 days). type "level" (default) → level series as stored valueCentimeters: centimetres above gauge zero for most gauges, but an elevation ×100 for groundwater wells and for gauges reporting an absolute elevation (Swiss gauges, the Neusiedler See) — divide by valueDivisor to read it in unit. type "discharge" → discharge Q in m³/s where the station provides it. Every result names the data provider in sourceNotice (search and flood situation: sourceNotices, keyed by sourceNoticeId); show that notice with any value, class or forecast you pass on, and the licence terms of the API require it.

Daily weather forecast at the station coordinate (DWD data via Bright Sky).

Newest published water-level forecast for a station: the median of the state agency model run, future points within the horizon. Only gauges whose state publishes numeric forecasts have one, so an empty result is normal. Indicative, not an official warning. Every result names the data provider in sourceNotice (search and flood situation: sourceNotices, keyed by sourceNoticeId); show that notice with any value, class or forecast you pass on, and the licence terms of the API require it.
