Ticking all the boxes

Sometimes an idea comes along that is just so good, so right, so advantageous on all counts that it is simply irresistible. This idea comes from the Americas, from the US Coast Guard. Adapted to the Irish inland waterways, and specifically to the Shannon, it could:

  • help to promote industry in recession-hit rural areas
  • create direct employment
  • help to stimulate indirect employment
  • promote Irish energy independence by reducing reliance on imported hydrocarbons
  • counter pollution of water-courses
  • reduce the number of heavy trucks using remote rural roads
  • use environmentally-friendly water transport, by barge along the Shannon
  • honour and promote the industrial heritage of Co Leitrim and the transport heritage of the Shannon
  • help to defray the costs of maintaining the Shannon Navigation
  • solve Dublin’s water supply problem, at least for non-potable water.

How could anybody resist?

The US Coast Guard has proposed that wastewater from fracking [PDF] should be transported by barge, rather than by truck or railway train, from the fracking sites to remote storage or treatment facilities. So, when fracking begins around Lough Allen, the wastewater could be carried down the Shannon by barge and, if necessary, pumped to Dublin.

It sounds like a winner to me.

Wasting sewage

An inquest has recently been held in Limerick, on the bodies of three seamen; and the jury gave a verdict, founded on the evidence of seamen and medical men, that the deaths had been caused by drinking the water of the Shannon, which the drainage of gas works and the common sewage had rendered poisonous. We trust that this unfortunate event, will induce the authorities of Limerick to take measures for applying sewage to the legitimate puspose of manuring the ground, instead of allowing a valuable material to go to waste, and to poison the waters of their river.

Lusmites rejoice

P J Norris commented here on the need for a walkway across Meelick Weir. The excellent KildareStreet.com tells us that the drought will end, as a Dáil written answer on 22 October 2013 showed.

Michael Kitt [FF, Galway East] had asked the Minister for Arts, Heritage and the Gaeltacht

… when it is proposed to reopen the walkway which spans the weir on the River Shannon in Meelick, County Galway; if funding has been provided for this work; if his attention has been drawn to the fact that this is an important local and tourist amenity; and if he will make a statement on the matter.

Jimmy Deenihan [FG, Kerry North/West Limerick] said

I am informed by Waterways Ireland that it is currently preparing a submission for planning permission to construct a new walkway over the River Shannon at Meelick. Indeed, environmental studies are underway to support the planning application.

I must advise the Deputy that construction work may only commence when all necessary permits have been received. It is Waterways Ireland’s intention to undertake works at the weir during 2014, subject to the appropriate statutory approvals being granted and financial resources being available.

Financial resources, eh? Perhaps a coin- (or note-)operated toll-gate on the walkway would be best.

Like the Mary Ellen Carter …

rise againJust a few weeks ago the depth was around 1.7m at Athlone weir, about 7″ above the navigational minimum. But today the depth is over 2.4m and, with staff gauge zero at 35.360m above Poolbeg datum, the water level is 37.760 m above Poolbeg datum.

WI’s budget: the minister speaks

I wrote here about the implications of the RoI 2014 budget for Waterways Ireland. The minister, Jimmy Deenihan [FG, Kerry North/West Limerick], spoke about it in the Dáil on Wednesday 16 October 2013 [h/t KildareStreet.com]. At the end of his lengthy contribution he said:

I am committed to developing North-South co-operation within the broader arts, heritage and commemorative activities of the Department as well as through the funding of North-South bodies. A provision of €38.3 million will be made available to support the two North-South implementation bodies, An Foras Teanga, comprising Foras na Gaeilge and the Ulster-Scots Agency, and Waterways Ireland. The provision will enable Waterways Ireland to deliver on its core activities and targets, which include keeping the waterways open for navigation during the main boating season and promoting increased use of the waterways resource for recreational purposes. This expenditure should also assist in developing and promoting the waterways, attracting increased numbers of overseas visitors and stimulating business and regeneration in these areas. Capital funding of almost €4 million will be made available to Waterways Ireland to facilitate the ongoing maintenance and restoration of Ireland’s inland waterways, thereby increasing recreational access along the routes of waterways.

The Government has reaffirmed its commitment to continuing to make progress, to improving the economy, to exiting the bailout, and to helping to create jobs. The Department and the sectors it represents will make a significant contribution to this work over the course of 2014.

I pointed out last year that Waterways Ireland is part of northsouthery and that, at budget time, we don’t get a breakdown of the northsouthery budget between An Foras Teanga and Waterways Ireland. In 2011, WI got roughly 60%, but I don’t know what happened after that. Here’s what I thought was happening last year:

Current spending (WI)

2010 Estimates: €25 585 000
2011 Estimates: € 24 335 000
2012 Estimates: €22 929 600 (60% of €38 216 000)

Capital spending (WI)

2008 Estimates: €11 000 000
2009 Estimates: €10 300 000
2010 Estimates: €8 000 000
2011 Estimates: €6 000 000 (or €6 002 000)
2012 Estimates: €4 500 000 (or €4 502 000) (100%)

In his speech, above, the minister said that northsouthery is going to get €38.3 million and that Waterways Ireland is to get capital funding of €4 million. However, the €4 million is included in the €38.3 million. The expenditure report [PDF; see page 160] gives these details:

  • for 2013 northsouthery had €36 210 000 of current spending; for 2014 it will get €34 425 ooo
  • for 2013 northsouthery had €4 080 000 of capital spending (all, or almost all, of which was for Waterways Ireland}; for 2014 it will get €3 958 000
  • the overall budget for northsouthery is down 5%.

We can calculate that the capital budget is down about 3%; the much larger current budget is down 5%. If WI gets 60% of the total, its current expenditure contribution from RoI will be €20 655 000, down over €2 000 000 from the previous year and about €5 000 000 since 2010, and its total current expenditure (85% RoI, 15% NI) will be €24 300 000.

The other interesting part of the minister’s speech is what WI is expected to do:

  • promoting increased use of the waterways resource for recreational purposes
  • developing and promoting the waterways
  • attracting increased numbers of overseas visitors
  • stimulating business and regeneration in these areas
  • increasing recreational access along the routes of waterways.

That should keep them busy. But I omitted one activity:

  • keeping the waterways open for navigation during the main boating season.

Emphasis mine, but does this mean that winter boating (at least if it involves staff time, eg at locks) will become a thing of the past?

 

Water levels in Athlone

At time of writing, the depth of water at Athlone Weir is 1.7m. “Staff gauge zero is 35.360m above Poolbeg datum”, which means the water level is 37.06m OD (Poolbeg). According to Bob Cullen’s 2002 article for Inland Waterways News [PDF], “The minimum navigation level in Lough Ree is 36.88m OD”, so if the level drops another 0.18m, about 7 inches, there may be a WI Marine Notice.

It seems that the dropping of the level of Lough Ree is intended to provide a buffer against flooding in the area from Athlone downstream to Meelick. According to Brian Hayes “A meeting between the ESB, Waterways Ireland and the Office of Public Works to review the interim operating regime is due to take place shortly.” [I have asked Waterways Ireland for a report on the meeting.]

But, if we are to believe the Dublin Evening Mail, the Shannon Commissioners took a rather more robust attitude to flooding downstream of Athlone: steamers [and PR] came first.

Erie warning: stuck with a sheugh

New York is a place in the Americas. There is a town of that name and there is also a state, whose economic development in the nineteenth century was assisted by the development of a canal, about which you can learn more on this excellent site. There is a trail along the canal that can be walked or cycled.

The canal is run by the New York State Canal Corporation, which is a subsidiary of the New York State Thruway Authority [a thruway is, it seems, a sort of road]. The canal loses money (naturally). The Thruway Authority sought to increase tolls; the State Controller said it should save money and improve management instead. Inter alia, it should

Commission an independent analysis of the Canal System to examine ways to streamline operations, seek new funding streams, and develop a realistically attainable vision for its future role in the upstate economy.

In his full report [Assessment of the Thruway Authority’s  Finances and Proposed Toll Increase [PDF] Office of the New York State Controller August 2012], the Controller said that

[…] the New York State Constitution forbids the Legislature to sell, abandon or otherwise dispose of the canals […]

but that

[…] choices regarding operational control and financial support for the Canal System are policy matters to be determined by the Governor and the Legislature.

His summary said that

Additional factors in the Thruway Authority‟s current weakened condition include the Authority‟s responsibility for financing and operating the State‟s Canal System as a result of legislation enacted two decades ago. The Canal System has consumed more than $1.1 billion of Thruway resources in the ensuing period. Contrary to the original legislative intent, responsibility for supporting the canals has diminished the Authority‟s ability to pursue its core mission. Moving the Canal System into the Thruway Authority was intended, in part, to stimulate tourism and economic development along the historic
canal corridors. This goal, too, has been elusive; boating activity on the canal has  declined substantially under Thruway control.

Later in the report he said

Second, the Authority‟s financial resources and organizational expertise, along with the then-newly created Canal Recreationway Commission, would position the underused Canal System to improve its facilities and marketing such that new users would be attracted from around the country, and even around the world.

Neither of these hoped-for outcomes has occurred. The Thruway Authority has invested more than $1.1 billion in the Canal System, and this drain of toll resources has also contributed to the deterioration of the Authority’s financial condition over the past decade. Meanwhile, despite major investments and new amenities, pleasure-craft activity on the Canal System in recent years is down by nearly one-third since the period immediately before the Thruway Authority assumed control.

The local media seem to take a somewhat more informed interest in their sheugh than do those in these parts:

Ireland and the United Kingdon could avoid finding themselves in these difficulties by refusing to recreate any more sheughs.

 

A wet winter?

Today’s Irish Times reports on yesterday’s launch of a report called Ireland’s climate: the road ahead [92.9 Mb 103 page PDF here]. The report predicts:

  • Daytime summer temperatures to rise by up to 2°C
  • Lowest winter night-time temperatures to rise by 2-3°C
  • Milder winters to reduce cold-related mortality rates
  • Wetter winters and drier summers
  • Increase in frequency of heavy precipitation event.

Chapter 10 “Climate change and catchment hydrology” covers river flows.

Met Éireann’s report on summer 2013 [2 page PDF] is available here; rainfall was down [on the 1981–2010 average] at all stations except Valentia; temperature was up everywhere and so was sunshine. So perhaps we’ll have a wet winter to look forward to.

Chambers, pots

Folk knowledgeable about canal engineering and artefacts might be able to contribute to a current discussion, over at the Helpful Engineer’s website, of the Four Pots overflow and the side chambers at Lock 16 (Digby Bridge) on the Grand Canal.

Water levels

Waterways Ireland is warning of low water levels on Lough Ree. You can see here how the level at Athlone Weir has changed over the past 35 days.
