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.

The Swiss Army Knife is no longer sprawling across the canal above Noggus Bridge on the Grand: it’s parked in the middle of the canal, closer to the bridge.

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.

An update on the Suir

I have updated my page about the River Suir above Carrick. I have added photos on some locations above Clonmel (Cahir, Athassel, Golden); I have also added a new section about the infrastructure of the navigation between Carrick and Clonmel. That section has benefited greatly from the information provided by Fred Hamond on the tour he organised for the Industrial Heritage Association of Ireland earlier this year. Several of the photos taken on the tour show warm, sunny weather. They will also, I hope, help to draw attention to the delights of the Suir.

Ephemera 6: canal stories

Two recent stories of people in canals in freezing weather. This one had a happy ending; this one didn’t.

Work in progress on the new moorings above the bridge in Killaloe.

WIP Killaloe 12 December 2010

Below the bridge, the downstream end of the canal has been blocked by a fallen tree. The ESB boats (62M and the tug) have been moved to the dockyard side (I don’t know whether that has anything to do with the blockage) and the path down the side of the marble mill has been blocked by a locked gate. It is climbable, but being burdened I did not attempt it.

The Swiss Army stop plank

Photographed 11 December 2010 from Noggus Bridge (N62) on the Grand Canal, south of Ferbane. As the Swiss Army Knife has been parked there for some time, I presume its function is to block boat access to Shannon Harbour while work is under way there. But wouldn’t some planks, or a couple of padlocks at Lock 32, have been cheaper?

If it is parked there for some other reason, I would be glad to know of it.

 

 

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.
