Canadian River Level and Flow Readings (Water Survey of Canada Real-Time Stations)

mscgeomet/river-levels-realtime

Real-time readings from a Water Survey of Canada hydrometric station: water level and discharge (flow) every five minutes, with the station name, province or territory and location, for a station number such as 05AE026. Returns up to 100 readings per call as a GeoJSON feature collection; readings come newest first and offset pages back through the retained window (about a month). Data Source: Environment and Climate Change Canada. Served by Eden Engine; not an official Environment and Climate Change Canada product.
