I have today sent this email to both Waterways Ireland and Clare County Council.
This email is being sent to Waterways Ireland (Scarriff office) and Clare County Council.
Let us suppose that, during the summer season (15 May to 15 September), I set off on my boat, with my dogs, from somewhere at the northern end of Lough Derg; I moor in Mountshannon at 11.15am.
Under Clare County Council’s beach bye-laws (number 16), I may not take my dogs ashore until 6.00pm: they will be confined to Waterways Ireland’s piers and pontoons. The entire area of the car park, the access from the piers to the roads, is off limits to dogs between 11.00am and 6.00pm.
Perhaps you might, for the convenience of visiting dog-owners, designate a corridor through which dogs (on leads) might be taken to land. After all, the area in question is not actually a beach: it is a car park.
… and a chance to meet WI CEO Dawn Livingstone.
NB the link is to a mailchimp site, not the WI site.
I have updated my recent post about the overgrowth of trees on the Shannon–Erne Waterway to welcome today’s news that “tree trimming and hedge cutting will be carried out at various locations on the Shannon-Erne Waterway” between September 2018 and February 2019.
I hope that “trimming” is a polite understatement and that the trees will be cut right back to, or beyond, the edge of the waterway.
I do hope that Waterways Ireland finds inspiration in this story from the Grauniad, wherein we learn that the Canal and River Trust, which manages many waterways in England and Wales, is able to charge over £12000 for city-centre moorings.
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.
Shannon Navigation/Removal of objects from the River Shannon
Waterways Ireland wishes to advise masters and owners of vessels that consequent to a recent Health and Safety Audit a number of unsafe jetties, ancillary walkways, practices and services have been identified in the vicinity of the Railway Bridge on the West Bank of the River Shannon (Watergate, Accommodation Road (R446)), on Waterways Ireland property.
As a result of the Health and Safety Audit it has been decided to remove all un-safely moored vessels, dangerous access platforms, walkways, electrical cables and any other fittings deemed to be unsafe.
Works will commence as operationally convenient after 20 December 2017. Removed items may be stored at owner’s expense in accordance with Shannon Navigation Bye-Laws.
Shane Anderson // Assistant Inspector of Navigation // 01 December 2017
A blue sleeping bag discarded near Binns Bridge in Drumcondra is the only clue that people once slept there.
On Thursday 2 November, fast and high waters covered the area under the bridge, and the pathway on either side of the canal that used to run under it.
In July this year, Waterways Ireland raised the water level to prevent homeless people from sleeping under the bridge, a spokesperson confirmed.
From a story by Laoise Neylon in the Dublin Inquirer on 8 November 2017. Well done to Ms Neylon for going and finding out stuff rather than just recycling press releases.
Here’s a map of the areas of the Grand Canal where eviction notices were served [PDF].
There must be some better way of responding to homelessness than by flooding people out.
