Irish GIS data

Not good enough, it seems: the Ardnacrusha headrace and tailrace are missing.

Pumps and crisps

Thanks to Colin Becker, I have updated this page to show the location of the ESB’s third pumping station between Meelick and Portumna: I had known only where two of them were.

I have also added to the page some rude remarks about the ESB’s policy of not revealing the clearance of their cables above navigable waterways. If, dear reader, you know of a change in the policy, or if you can effect such a change, or if you know the clearances, do please let me know by leaving a Comment.

 

Salmon at Ardnacrusha

Might a salmon cannon work?

In my youth, I tried angling once or twice, but with no success: the only time I ever caught fish was with mackerel feathers. So, despite having read Isaak Walton (several times), angling doesn’t really interest me. But it’s hard to read this without accepting that Something Must Be Done, whatever it is. Note, in particular, Dudley Mallett’s comment.

Erne eels

Dr William O’Connor has been checking on eels on the Erne too.

An update here and, from across the water, here.

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 ….

Relieving Athlone

Parteen Villa Weir is sending large amounts of water down the original channel of the Shannon, and over the Falls of Doonass, to draw water off from the upper reaches of the river.

Levels below Parteen Villa have not yet reached those of 2009 and the channel can probably take more before folk get flooded.
