Irish hydrometric archive and station register
The Office of Public Works' full hydrometric archive — the record older than the five weeks waterlevel.ie serves — together with a station register naming, for each gauge, the water body it sits on, its catchment and its river basin district.

Notes
Assessed on 26 August 2026 while building the Sprint 7 water-body linkage, and refused. It is the one source that would have resolved Ireland: its station register carries a water-body name, a catchment and a river basin district for each of the 490 level stations, keyed on a station number that maps cleanly onto the identifiers Hydrionis already holds — Sandy Mills is 01041 on the Deele, which is correct. It would have linked roughly 450 Irish gauges in one step, and it would also have supplied the historical record that waterlevel.ie’s five-week window does not. Two things stopped it. The agreement is a gate, and beyond the gate the terms grant no reuse licence: they are a liability waiver that also requires anyone passing the data on to carry the data-quality conditions with it, which is a restriction on redistribution rather than a licence permitting it. Publicly reachable is not the same as reusable. So Ireland’s gauges stay unlinked, which is the honest outcome — spec §5 is explicit that an unresolved gauge is better than a wrong river, and it follows that an unresolved gauge is also better than a right river obtained improperly. Worth pursuing directly with the OPW, who publish a contact address for the archive.
