Pollboy Lock

I mentioned some time ago that, according to its Business Plan 2015, Waterways Ireland was considering automating Pollboy Lock, on the River Suck to Ballinasloe, in order to save costs. Like other offshoots from the main Shannon Navigation [Killaloe to Lough Key], the Suck is relatively little used.

According to the Connacht Tribune, the automation is to proceed and the lockkeeper is to be reassigned. It seems that some local councillors and “business interests” — who do not, as far as I know, contribute to Waterways Ireland’s income — regret the loss of an ambassador for the town. The keeper, Mr Coyne, was indeed extremely helpful to visiting boaters.

However, he could help only those who arrived at his lock: he could do nothing to attract more boating visitors to the town. That is not in the least a criticism of him, but rather a suggestion that councillors and business interests might perhaps have done, or yet do, more to attract visitors and increase the usage of the splendid harbour in Ballinasloe. Perhaps they might even appoint and pay a town ambassador?

A Sinn Féin councillor quoted in the article seems not to be entirely familliar with the duties of lockkeepers. Furthermore, he does not take account of the fact that the Shannon–Erne Waterway succeeds without lockkeepers — or that it was proposed that the Clones Sheugh [not-the-Ulster-Canal] operate in the same way. Surely a Sinn Féin councillor is not suggesting that, without keepers, the Sheugh might not be the enormous success that his party purports to believe it would be?

PS: the Tribune also has a piece about rubbish at Castle Harbour, Portumna.

 

Swimming in the Naller

On 22 September 2015 Eric Byrne [Labour, Dublin South Central] put a written question to the Minister for Fairytales:

To ask the Minister for Arts, Heritage and the Gaeltacht her plans to review the no swimming in locks and harbours under the by-law within the Canals Act by-laws of 1988 in view of the fact that there is no penalty for ignoring such signs; and if she will make a statement on the matter.

The minister replied:

I have been informed by Waterways Ireland that while it has not determined a need for an associated penalty with this by-law at this time, the matter is being kept under review. I am advised also that the locks, docks and harbours are manned and/or frequently visited by Waterways Ireland Operations and Inspectorate Authorised Officers. Where swimmers are encountered, they are made aware of the by-law provision and the dangers of swimming in or near canal infrastructure and they are requested to remove themselves from the navigation. Such requests are normally acceded to. In the event of persistent offender(s) unwilling to obey direction from Waterways Ireland Authorised Officers, the assistance of An Garda Síochána is sought to remedy the situation.

Sometimes I wonder whether politicians have any grasp on reality. Swimmers in the Naller are a force of nature and are as far beyond the control of Waterways Ireland, the police and indeed politicians as hurricanes, the economy or Mick Wallace. People have been swimming in the canals, in Dublin and no doubt elsewhere, for generations, and nothing or nobody has been able to stop them.

I suspect that more people have swum in the canals than have ever boated on them; swimming is therefore a legitimate topic for waterways studies. Here is a preliminary contribution to the field.

Grand Canal passage-boat

Here is an account, published in 1862, of what it was like to travel from Portobello, in Dublin, to Ballinasloe by the Grand Canal Company’s passage-boats — and of why rail travel was much to be preferred.

Shannon traffic figures to May 2015

I am grateful to Waterways Ireland for letting me have the Shannon traffic figures for the first five months of 2015. All the usual caveats apply:

  • the underlying figures do not record total waterways usage (even for the Shannon) as, for instance, sailing, fishing or waterskiing on lakes or river stretches, which did not involve a passage through a lock or Portumna Bridge, would not be recorded
  • the passage records would not show, for instance, a change in the balance of types of activities from those in larger cruising boats to those in smaller (sailing, fishing, waterskiing) boats
  • figures like these will not necessarily be representative of those for the year as a whole. The winter months, January to March, see little traffic in any year; for April, May and June, the weather can have a large influence on the amount of activity especially, I suspect, in private boats.

On the other hand, the figures do include the Shannon’s most significant tourism activity, the cruiser hire business. And they are our only consistent long-term indicator of usage of the inland waterways.

The big news is that there is an increase in the amount of hire-boat traffic and a decrease in the amount of private traffic. [Personal observation suggests very little activity on Lough Derg, apart from the sailing bods.]

All boats. Note the slight increase in total traffic — or is it a dead-cat bounce?

The increase comes from hire-boat traffic …

Shannon traffic Jan to May 2015 private boats

… as private-boat traffic is down on last year

Shannon traffic Jan to May 2015 compared with 2003

Nonetheless, hire-boat traffic is still close to 40% of what it was in 2003, with no sign of a major recovery

Shannon traffic Jan to May 2015 private -v- hire

But, at least for April and May, hire boats are the major users of the Shannon

In January, 18 boat passages were recorded, 9 of them at Portumna Bridge. There were 20 passages in February and 362 in March. Is there any point in keeping the Shannon open throughout the winter?

In the first five months, 11 boats used Sarsfield Lock, the sea-lock in Limerick. There were 88 passages through Pollboy Lock on the River Suck. On the Lough Allen Canal, 96 boats went through Battlebridge Lock, 95 through Drumleague and only 38 through Drumshanbo. These branches can’t be paying their way.

 

ESB and the Shannon

I wrote here that I had written to the ESB, on 27 May 2015, to ask about navigation on the Shannon from Castleconnell downstream. One month later, I have not yet received a reply.

I did hear this weekend that ESB had contacted certain boat-owners to inform them that they were not to moor to the ESB embankments between Portumna and Meelick. As a riparian landowner, ESB is no doubt within its rights, but it would be interesting to know how much of the bed of the Shannon it claims to own in that area.

I have still not been able to find out, from the ESB, the clearance under its high-voltage lines crossing the Shannon (and other navigations). I gather that the ESB works on the principle that, if it provides no information, it can’t be blamed if owners of masted vessels electrocute themselves, whereas if it did provide information it might be sued. Strange that a public sector body should have such a blasé attitude to the prospect of the electrocution of the citizenry.

Perhaps if I asked questions under the Access to Information on the Environment Regulations 2007/2011 I might get replies.

 

Please don’t look at these photos

I regret to say that I have published, on these pages, several photos of the Shannon, Parteen Villa Weir, Ardnacrusha hydroelectric power station and its headrace and tailrace canals.

The storage basin between the road bridge over the River Shannon at Killaloe and the weir and canal intake at Parteen, including the right and left embankments constructed to form the said storage basin, together with the land outside and along the said right embankment delimited and separated from the adjoining land by post and wire fencing and also the land outside and, along the said left embankment delimited by the left bank of the Kilmastulla River Diversion.

And I have lots more photos … here and here and here, which I ask readers not to look at either.

You see the thing is, Your Honour, Sir, I didn’t know. I didn’t realise that, under Statutory Instrument 73 of 1935 Shannon Electricity Works (Declaration of Prohibited Place) Order 1935, the places as described are prohibited places under paragraph (d) of Section 3 of the Official Secrets Act 1911, as amended by the Official Secrets Act 1920, and as adapted by or under the Adaptation of Enactments Act 1922 (No 2 of 1922). That’s because

information with respect thereto, or the destruction or obstruction thereof, or interference therewith, would be useful to an enemy.

Apparently, under those acts, giving anyone information about a prohibited place is a felony, punishable by imprisonment for up to fourteen years.

Wikipedia says that, in Ireland, those acts were repealed by the Official Secrets Act 1963, but was the statutory instrument repealed? I don’t know, but I’ve written to the Department of Justice to ask.

In the meantime, please don’t look at the photos, especially if you’re a Foreign Agent: a term that, under the 1963 act,

includes any person who is or has been or is reasonably suspected of being or having been employed by a foreign power either directly or indirectly for the purpose of committing an act (whether within or outside the State) prejudicial to the safety or preservation of the State, or who has or is reasonably suspected of having (whether within or outside the State) committed or attempted to commit any such act.

I wonder whether that includes the European Central Bank.

Interesting info from Waterways Ireland

Two interesting PDF documents available on this page:

No mention of Saunderson’s Sheugh, but I suppose dredging of the River Finn is proceeding.

Backtracking the Barrow trackway

Some time ago I put up a page about the Barrow trackway [towing-path]. For some reason, the page disappeared shortly afterwards. I have now recreated it; unless or until it disappears again, it is here.

Interesting information about the Ulster Canal …

… as distinct from ministerial reelection photo opportunities.

By the way, some folk get confused about the location of the Ulster Canal; this map may help:

Saunderson's Sheugh -v- the Ulster Canal (OSI ~1840)

Saunderson’s Sheugh -v- the Ulster Canal (OSI ~1840)

Anyway, for folk who are interested in weightier matters than ministers talking through portions of their anatomies that they can’t distinguish from their elbows, here is some speculation about opening bridges on the Ulster Canal.

That’s the Ulster Canal Ulster Canal, not the Saunderson’s Sheugh “Ulster Canal”, by the way.
