Hydrionis / UK water Why there is no page per station
Six thousand monitoring points would make six thousand near-identical pages, each thin, each competing with the others, and none of them what anyone was looking for. Hydrionis’s own both rule that out. The stations are real geographies in the registry and every value is addressable through the API — they simply do not each get a URL. What they get is this index, the charts on the pages that do exist, and the bulk downloads.

Station-years of record
Where they are River gauges and observation boreholes held by Hydrionis
Flow gauges in blue, groundwater boreholes in amber. Only stations whose record opens before 1970 are collected, which is why coverage is thinner than the Environment Agency's full network.
River gauges and observation boreholes held by Hydrionis 720 locations, each labelled individually.

The longest river flow records Ordered by when the record begins. Flow is a property of the gauge and its reach, not of the river as a whole, so two gauges on one river can differ by an order of magnitude.
The longest groundwater records Levels are metres above Ordnance Datum and are specific to each borehole and its aquifer. A level below zero is ordinary where the water table sits below sea level, and absolute elevations from different boreholes are not comparable with one another.
