Big it up for the OPW

I’ve just been reading some particularly nitwitted Dáil discussions and I need some time to calm down enough to report on them to the Learned Readers of this site. Let me just say that anyone who thinks that politicians cannot distinguish fact from fiction is absolutely right. But enough of that for the moment.

I reported earlier on an oddity in the results from the OPW’s Athlone waterlevel gauge. I emailed the OPW about it and a helpful chap got back on more or less immediately.

He explained that the data we see on the waterlevel.ie site is, as it were, live: raw unfiltered data with nothing added, nothing taken away. The same data goes in to the OPW and they spotted that the Athlone gauge was reading too high. They found the sensor was faulty; they have now adjusted it and the new, lower readings are correct.

The disappearance of the placenames is because of some work in progress on improving the website; they will be back.

He kindly pointed me to a list, in .xlsm format, downloadable from here; it shows all hydrometric stations in Ireland. It shows who operates them, whether they’re active and whether they use telemetry (which I take to mean that they can be monitored remotely). Unfortunately OPW itself doesn’t seem to have any gauges on Lough Derg and nor does Waterways Ireland. OPW does have a rather excitable gauge at Scarriff and gauges upstream of Meelick Weir and Meelick (Victoria) Lock. The ESB has gauges with telemetry at Ballyvalley (25073) and Killaloe (25074) but I can’t find any website giving the levels. If, Gentle Reader, you can find one, perhaps you would let us know.

The consoling part of dealing with the OPW is that you get the distinct impression that they know some useful stuff. Unlike, say, some folk working in Kildare Street ….
