Gauge Stations on a German Federal Waterway, with Station UUIDs (PEGELONLINE)

pegelonline/stations-on-waterway

Lists the gauge stations on one German federal waterway in the PEGELONLINE network, given the waterway's name or short code as listed by the waterways tool (for example RHEIN, ELBE or MAIN; case does not matter): for each station its UUID, station number, name, position along the waterway in kilometres, latitude and longitude, operating office, voice-service number and waterway. Use the UUID with the station details tool. One waterway per call; a name the service does not know returns an empty list, not an error. A long waterway returns tens of kilobytes (the Rhine has 36 stations). Station records only, no water level readings.
