I have been known to complain about the absence [on the interweb] of information about the state of the Shannon downstream of Banagher and Meelick.
On the Waterways Ireland website, on the “About Us” menu, there’s a “Water Levels” option which takes you to this OTT Hydromet page. Perhaps my security settings are too high (or too eccentric), but at the top of the page all I see is
Alternate HTML content should be placed here. This content requires the Adobe Flash Player. Get Flash
At the bottom I read
Click here to obtain list of todays 9am Values. Please Note – Levels are recorded in meters to MSL Malin Head.
There is also a disclaimer.
The link goes to this page where the locations of various gauges are categorised by waterway. The furthest south [on the Shannon] I can find is …
Meelick Weir Gauge SS_MEELICK Water level 0001 32.62m 2018-07-07 07:30:00 5400
… from which I deduce that the water level at Meelick Weir is 32.62 metres above mean sea level at Malin Head. From that, of course, I can deduce the depth of the water at Meelick, or I could if I knew how far the bed of the river was above MSL Malin Head, and by charting the daily returns I could see whether the level was increasing or decreasing.
Alternatively, I could use the OPW’s gauge at Banagher, only a little way upstream, which shows me the depth, the change over 35 days and the level in relation to various percentiles of previous levels. That is a lot easier to read and a lot more useful: although a measure of flow would be more useful still, I can assume that a high level will be accompanied by a faster flow.
I have recently discovered that the ESB has a page with (admittedly for a small number of sites) information in a more user-friendly format than either WI or the OPW. To find it from the home page, select “Our Businesses”, then “Generation & Energy Trading”, then “Hydrometric Information”, then “River Shannon”, then “Beware of the leopard”. Alternatively, try www.esbhydro.ie/shannon for a list of PDFs.
Either way, the files available include
- a hydrometric forecast for the Shannon
- one-year charts showing levels at each of five locations: Bellantra sluices, Lough Ree; Thatch, Lough Ree; Athlone Weir downstream; Portumna Bridge; Pier Head, Killaloe
- even more useful for anyone going near Killaloe Bridge, the total flow [in cubic metres per second] at Parteen Villa Weir and at Ardnacrusha.
Here, in flagrant breach of the ESB’s copyright, is the chart for Parteen Villa Weir:
The flow has been pretty well flat, at 0, for some time. The Parteen and Ardnacrusha charts have accompanying tables giving the figures for the last 30 days; here are those for Ardnacrusha:
Each of Ardnacrusha’s four turbines uses about 100 cubic metres per second [cumec]. The flow through Parteen Villa Weir is divided between the old course of the Shannon [which must get 10 cumec] and the new channel through Ardnacrusha. The combined flow through Parteen has been 11 cumec for the past week, and Ardnacrusha has been getting nothing (except a tiny amount on 3 July). That explains why the level of water at Castleconnell, on the old course, is slightly higher than normal summer levels (11 rather than 10 cumec).
And with no water going through Ardnacrusha, the level of Lough Derg is normal (see the chart for Killaloe) and there is no strong current at Killaloe.
Note, by the way, that the levels shown by the ESB are referenced to the older Poolbeg ordnance datum, not the Malin Head used since 1970: “Poolbeg OD was about 2.7 metres lower than Malin OD.”
If, Gentle Reader, you know of any other accessible web pages with user-friendly information on flows or depths on the waterways, do please leave a Comment below.
To the Editor of the [Dublin] Evening Mail
In your impression of the 3d instant, under the head of “The Famine Advances and the English Press”, I find a reference to the (so called) improvement of the Shannon; that of the sum of £313009 advanced by government, £230325 has been repaid. In this case you say (and most truly say) “the jobbing was most flagrant, and the reckless waste of the public money unparalleled”.
So far you are correct, but you are, no doubt, labouring under a very common mistake when you say the works have very recently been completed, such not being the case. Some handsome bridges, with swivel arches, and spacious locks — one in this neighbourhood too small to admit an ordinary river steamer. Nor was the level properly taken, there not being sufficient water to carry tonnage drawing more than 5 feet 6 inches, during the greater part of the summer.
Now, I should wish to know, through your well informed medium, to what cause is to be attributed the present state of the weir, or lock dam, adjoining Tarmonbarry, a span of nearly 500 feet. Owing to the improper manner in which the same has been executed, upwards of 60 feet have given way, and when examined by the engineer of the board, the entire is found in such a state as will involve the rebuilding.
In justice to this gentlemen, I am bound to say he was not the engineer under whom it was constructed, nor do I think, until very lately, he had anything to do with the Shannon Commission, every work in which he has been engaged, being acknowledged to be well executed.
I am not aware whether you are in possession of this fact, that in order to make the Shannon improvements available or remunerative, it has been considered necessary to construct a canal to “Lough Erne”, adjoining Belturbet, and thence to communicate with Belfast, by “the Ulster canal”. You will, I am sure, agree with me in the old adage, that “this would be going round the world to look for a short cut”; but the cut I allude to is not so short, as it involves, I am informed, thirty miles of new canal, and several large and expensive locks.
But, Sir, I must inform you, that the tolls of the river Shannon, from Carrick-on-Shannon to Limerick city, are barely sufficient to pay the lock-keepers’ salaries. The Shannon Commission I would henceforth style “the Shannon job”.
I remain, Sir, though a bad dancer, one who must
Pay the Piper

First, a caveat. The links below are to a site called Brinkwire, about which I have found little independent information. I cannot say that the site is safe to visit or that its information is reliable.
The site itself says that it is
… a news hub for blogs, online communities, content affiliates, publishers and members of the connected internet who are interested in commercial news.
Brinkwire charges PR agencies, marketing agencies and in-house communication teams to upload their news to our hub.
The story about the Shannon is here. It says (inter alia)
The plight of a suckler farmer on the banks of the River Shannon in Co Offaly encapsulates the many challenges facing small Irish farmers today.
Paddy Towey (63), who has been farming in Shannon Harbour for over 10 years, had tears in his eyes as he expressed his belief that this season may well be his last.
He was pleased to hear that work was planned to remove the top portion of Meelick Weir, but he said the measure has come too late for him.
Mr Towey has been affected by floods.
The story is said to be “BY BRINKWIRE ON “; it is not clear what PR agency, marketing agency or in-house communication team might have placed it there.
In looking at the map of Ireland, it has appeared to me that it may be found of advantage to prevent the waters of Lough Allen from flowing into the Shannon, and to cut a channel in a north-westerly direction, along which they may run into Sligo Bay. By this disposition of the waters of Lough Allen, not only will the channel of the Shannon be relieved from the superabundant water which now flows along during the rainy season, but they will act very beneficially in scouring out the harbour of Sligo. The Shannon might likewise be made available to the supply of power to several valuable mills to be erected on its course.
The Report of Mr George Stephenson, Civil Engineer, London, 9th July, 1831, to the Committee appointed to inquire into the practicability of improving the navigation of the Shannon, and for draining the lands in the vicinage
Minister Naughten also announced that Meelick Weir just north of Lough Derg will be removed.
Of course if the weir is removed there will be no point in restoring the walkway.
I have suspected for some time that Britain’s Brexiteers are actually Sinn Féiners.
After 1916 the Irish Shinners decided to leave a larger economic and political entity and to do so without any business plan or any realistic idea of how their proposed state would make a living.
After 2016 the British Shinners decided to leave a larger economic and political entity and to do so without any business plan or any realistic idea of how their proposed state would make a living.
One lot of Irish Shinners, led by the lunatic Éamon de Valera, wanted a hard Irexit and started shooting the soft Irexiteers who, happily, managed to keep control; it is to be hoped that matters don’t go that far in Britain.
It may be objected that the evidence for this contention, that Brexiteers are Shinners, is a little light, but I have now found confirmation: Boris Johnson is an enthusiast for insane canal construction projects.
The mark of the Shinner is upon him.
