Lagan Navigation: Ballyskeagh High Bridge

A brief account here, with some photographs and some thoughts on the design of the locks of the Lagan Navigation.

Lough Derg water level

The water level on Lough Derg is very high, flowing over the guard lock at Killaloe.

 

Bare ruined choirs, where late the sweet birds sang

The old Limerick Navigation included a section of canal at Killaloe, with three locks. The uppermost, now disused, is still visible at Killaloe; the middle lock (Moys) is accessible by small boat; the third (Cussaun) is under water in the Flooded Area created by Parteen Villa Weir. The wall that divided the canal from the river downstream of Killaloe bridge forms an island whereon are the former eel-packing station run by the ESB, the former goods store (inhabited by Waterways Ireland) and the former marble mill (now an ESB engineering works). The island hosts the Killaloe market on Sunday mornings.

The curious can (obstructions permitting) walk a little further downstream to where the wall was breached, allowing boats to access the canal below the bridge without having to go as far as Moys Lock.

The west side of the canal, below the slip, was lined with trees.

Waterways Ireland Marine Notice 86 of 2011

MARINE NOTICE No. 86 of 2011
Shannon Navigation
Lough Derg
Killaloe Canal

Canal Maintenance – Tree Cutting

Waterways Ireland wishes to advise all masters and owners of vessels that tree cutting will take place along the Killaloe Canal banks from the vicinity of the cathedral downstream to the lower entrance from the river
Shannon, from Monday 19th Sep until about mid Oct.

Access to this section of the canal will be closed during this period. […]

Marine Notice 24/2012 of 16 March 2012 said

Works are still ongoing along the Killaloe Canal banks from the vicinity of the Cathedral downstream to the lower entrance from the river Shannon.

Access to this section of the canal will be closed until further notice.

That notice has not (as of 10 June 2012) been withdrawn so it must be assumed that the works continue.

Mullingar

The Met Éireann report [PDF] for spring (March to May) 2012 shows that rainfall measured at its Mullingar station was only 59% of the average for 1981–2010.

Towpath: legal case about access

The Irish Times has a report here.

Kildare Nationalist

Look out for Aoife Barry’s article “Hidden Gems: Local Canal Ways” in the “news from Naas” section of the Kildare Nationalist of 29 May 2012. It’s not yet on the website but should be soon.

Just in case you were wondering …

Grand Canal basin: barriers of various kinds

The Dublin People has the story.

Don’t those fluorescent colours look disgusting? Enough to give you a headache. Bring back the gas works, say I: at least they could cure whooping cough.

WI’s brand identity

According to this website it …

[…] had to represent an All-Island body, reflect its unique authority and represent its core values of Strength, Distinctive, Independent, Caring, Environmental and Connecting.

I can see that.

I wonder why only one of the values is a noun.

 

Shannon traffic figures, first four months of 2012

The Shannon traffic figures for the early part of the year need to be treated with caution. As at other times of the year, the figures show only vessels that passed through locks (and Portumna Bridge), so boats out on the lakes, or on the river between locks, will not be recorded. So the traffic figures don’t tell us the total amount of traffic; their main use is in showing trends from year to year.

The figures for the early months have a further disadvantage. Numbers of passages are low anyway and a single event — especially a weather event like floods, ice or gales — can have a major effect on winter and spring traffic, whereas the effect might be much smaller on the figures for the whole year.

I am grateful to Waterways Ireland for supplying the figures. I have them for each counting point, but won’t give all that detail here.

January 2012: 35
February 2012: 59
March 2012: 642
April 2012: 3316
Total: 4052

To put that in context, here are the figures from 2002 onwards:

Year J F M A YTD 5YMA
2002 10 6 1331 3528 4875  
2003 10 35 644 5515 6204 5157.4
2004 60 52 424 4768 5304 5524.6
2005 13 54 2162 3123 5352 5848.6
2006 37 55 591 5205 5888 5423.4
2007 42 85 698 5670 6495 5358.2
2008 28 44 1377 2629 4078 4991.0
2009 42 82 563 4291 4978 4849.6
2010 30 45 495 2946 3516 4363.o
2011 48 66 512 4555 5181  
2012 35 59 642 3316 4062  

The YTD column is Year To Date; 5YMA is a five-year moving average, which might remove some of the distortion caused by one-off events like ice and floods. I still wouldn’t read too much into four months’ figures, but the general trend is downwards.
