Clonmel

Here is a short piece about the Suir in Clonmel and the opportunities for appreciating its natural and built heritage.

Ephemera 10: the pontoons at Ballina

Do my eyes deceive me?

The still-unopened mooring pontoons below the bridge at Ballina (bottom of Lough Derg) seem to have sprouted an extension.

Here is what they looked like in 2009.

Here they are in the floods of November 2009.

And here they are in January 2011, seen from downriver.

Well I never.

 

 

 

Ephemera 9: the flash lock at Killaloe

As part of its new mooring scheme at Killaloe, Waterways Ireland has commissioned contractors (L&M Keating Ltd) to carry out various works including the installation of a lock at the upper end of the canal, beside the Phoenix boathouse and just downstream from the Pierhead. The lock is to control access to the canal; presumably the stop planks in the existing lock chamber will be removed, allowing boats to pass down under the bridge.

The lock under construction

As I understand it, this lock is to have a single pair of gates. Boats wishing to pass through will tie up temporarily and use a squawk-box (or similar technological marvel) to communicate with the bridge-keeper at Portumna, who will cause the gates to be opened and then, presumably, closed after the boat has passed through. This system will prevent the use of the canal by cads and bounders using jetskis, speedboats and other excrescences.

Stanked off and pumped out

However, the water through Killaloe Bridge has a gradient or slope, especially in flood and when Ardnacrusha power station is running. The canal above the lock will be at the higher level; the canal below the lock will be fed from the bottom end, where it rejoins the river. So is there not likely to be a difference in height at the lock? Is this the equivalent of a flash lock?

I’m sure there is an engineering answer to this; I would welcome enlightenment.

 

Up the Suir

I don’t know if you remember, but a few months ago we had sunshine, and it was warm outside. Back then, at the end of May in fact, I went on the Industrial Heritage Association of Ireland‘s tour of Carrick-on-Suir, Clonmel and areas in between.

In Carrick, Ralph O’Callaghan showed us some of the sights and addressed the group in the Heritage Centre. Here are some of the things he showed us.

This yawl is equipped for sand-dredging

Note the large rudder

After lunch, I was fortunate to be one of two people who got a trip in Ralph O’Callaghan’s canoe, from Kilsheelan upstream to the Anner bridge just downstream of Sir Thomas’s Bridge, which is itself downstream of Clonmel.

I have set up a small (approx 120-photo) slide show to give an idea of the conditions on the Suir at the time. The water level was low after several dry weeks, but the previous winter’s floods may have left more silt than usual. At any event, a successful passage required Ralph’s skills and his intimate knowledge of the river and its weirs. You can see some of the weirs, and the gorgeous scenery, in the show.

I am very grateful to both Ralph O’Callaghan and Fred Hamond for facilitating the boat trip and for sharing their immense knowledge of the Suir.

If you like interesting boats, you’ll like Ralph’s canoe.

Killaloe to Limerick Docks via Ardnacrusha

Join the ex-Grand Canal Company motor-barge 68M on its trip from Killaloe to Limerick Docks, carrying barrels of stout for Dolan’s Pub. The trip marked two occasions: Arthur’s Day, the annual Guinness marketing opportunity, and the fiftieth anniversary of the last commercial cargo on the Grand Canal and the Shannon, which was a shipment of stout to Limerick.

This page provides a slide-show of 300 photos taken from 68M on its journey. If you can’t make the trip in person, do it this way.

Note that the page takes some time to load. And, even clicking through pretty fast, the show is likely to take at least ten minutes.

Click on the first photo to bring up the controls. If you have any problems with it, leave a Comment to let me know. I haven’t done this before. I may not be able to fix any problems, but I can at least look into them.

Who took the arch? A Shannon whodunnit

O’Briensbridge is a village in Co Clare, islanded between the headrace of the Ardnacrusha hydroelectric power station and the River Shannon. Up to 1929 the river was the navigation between Limerick and Lough Derg (and eventually Dublin), and the bridge itself was something of an obstacle to navigation.

In 1832 the engineer Thomas Rhodes drew a sketch of the bridge with 14 arches, whereas nowadays it has only 12. We know when the seven arches on the Co Limerick side were reduced to six, but it has not been clear when an arch was removed from the Clare side. I think I know the answer; you can read it here.

The barge at Plassey: seeking experts on iron

On my old photographic website I had a page of photos of an abandoned barge at Plassey, on the River Shannon. I have now moved those photos to here and added some text.

I am hoping that someone expert in old iron barges might be able to make a guess at the age, and perhaps even the origin, of the barge. I will, in the meantime, be trying to pin down the date of its abandonment.

 

User surveys

Last Saturday, I had just checked that the nineteen members of the Inland Waterways Protection Society, and accompanying walkers from O’Briensbridge Community Group, IWAI Lough Derg Branch and elsewhere, had successfully crossed the Shannon at Plassey, using the University of Limerick’s road-bridge instead of the Black Bridge, which is still closed after last year’s floods.

I was walking back to my car, so that I could drive to meet the group at Gillogue and ensure that they were getting their sandwiches at the Lame Duck, when I was accosted by a woman in a car. It was pouring rain and my dogs were getting impatient, but I listened politely while she asked if I would participate in a survey. “For whom?” I asked. “For Waterways Ireland,” she said. So I thought I’d better play along.

The survey was conducted as she sat in her car, dry, but obstructing the traffic, while I stood outside in the rain, keeping an anxious eye on the dogs. I was not inclined to prolong the time spent answering questions.

Now, I was told recently (after submitting an FOI request) that the towing-path and bridge at Plassey were leased by the Department of Finance to Limerick County Council, so it’s not entirely clear what Waterways Ireland has to do with the current management of that stretch or why it wanted user views. Did the interviewer choose that stretch as a bit of Limerick in which she could see water while staying in her car?

I was asked what I thought of the facilities “toilets and so forth”, and pointed out that there weren’t any. I struggled to convey the fact that, although I was walking before I was accosted, I disliked the activity intensely (especially in the rain) and that, although I visit Plassey several times a year, it is because I am interested in industrial archaeology, not because I want exercise. And there didn’t seem to be a way of conveying that I had organised for about twenty-five other people to walk the towing-path, but that I wasn’t myself participating.

Then I was asked if I had heard of Waterways Ireland and if I knew what they did ….

The 2004 survey is available from WI’s website here. But I wonder whether WI commissioned any surveys between 2004 and 2010 and, if so, where they are to be found.
