It’s not often you feel relieved to see a canal with a lack of water in it, but the fact that the cofferdam has drained itself whilst not refilling itself is great. I think it was about a month ago that it was this empty.
30/3/21
25/2/21 upside down for comparison
There are a few things to note from todays photos, other than it’s a lovely day to go boating!
The western end of the cofferdam seems to have improved water levels, so no overtopping.
30/3/21
The aggregate ramp into the cofferdam has been added to. The pile driving crane is no longer on the floating pontoon. In the photo above you can see what looks like a light with a red box standing on some new aggregate which I think will be used to illuminate the area and down into the drain.
The bags that were dropped in by helicopter are very visible now.
30/3/21
So is the big hole in the towpath by the blue tarpaulin.
30/3/21
What can also be seen in the above two photos is a yellow pump on the north bank by the drain.
30/3/21
There is now a small tarpaulin dam in the drain and the yellow pump appears to have two hoses one to either side of the dam.
30/3/21
Now that the water in the cofferdam has drained down into the drain below, as much as the breach will allow it, my theory is that the drain under the canal will now be pumped out. This will give them access under the canal.
30/3/21
The cofferdam seems to be holding its own now, hopefully things can progress. Will they need to do a fish rescue?
30/3/21
Then, at last, they will be able to pump out the remaining water to reveal the canal bed and the breach itself.
30/3/21
According to a local boater who has recently spoken to the control at Goole Docks, they are still not permitted to pen leisure craft through the locks onto the Ouse. He was told to contact C&RT for updates.
The tide at Goole this evening was going to be high 6.5m, 3 ships would be leaving the docks and 3 more coming in. Both locks in operation. Here’s hoping the high tide means the level doesn’t drop too much in the marina. I hope we left our ropes slack enough!
Other good news is that the Figure of Three Locks on the Calder and Hebble will be reopening on 12th April. This means that if we ever get to leave Goole this year then we might just be able to cross the Pennines via Standedge Tunnel.
Thank you to Mark again for the use of his photos.
We have experienced a few challenges with the coffer dams at the breach site during the weekend.
To help manage this we have had to drop levels between Ferrybridge and Pollington, therefore fluctuations in water levels may be experienced over the next few days as work continues at the breach site on the long term repair.
Skippers of all craft are advised to check their mooring lines to ensure their vessel is securely moored allowing for water fluctuation.
We apologise for any inconvenience this may cause.
Levels had been overtopping the cofferdam at the western end over the weekend. The prevailing wind not helping. A video from Lisa shows the extent of this. Finger credit to Lisa.
The Aire and Calder appears to have no spillway between Ferrybridge and Goole unlike most canals. Spillways help to keep the level of a pound at a certain level or below, but the spillway to this pound is the docks in Goole which when ships are coming and going with the tides works pretty well. But now the cofferdam is in the way water needs to be pumped round it to supply the docks with sufficient water and to help keep the level above the cofferdam at a suitable height.
This all means that it is a bit of a balancing act to keep the levels at suitable heights for all. The levels in the docks for ships to come and go. The moorings in the docks. The moorings at Rawcliffe Bridge. Low enough not to overtop the cofferdam. Above the cofferdam the moorings below Pollington Lock.
Ferrybridge where there water can be let into the canal from the river
Levels seem to get dropped all the way to Ferrybridge, which suggests that this is the only place where they can control the amount of water coming into the canal. Tracking Google maps towards the breach there may be one sluice above Whitney Lock where the level could be dropped, but this goes into a drain rather than a river, so could end up flooding fields.
The height of the cofferdam seems to be an issue that comes and goes. They are planning on raising the level of the piling at the eastern end, handy as that is where the work pontoon is. But will they be able to do the same at the western side? Do they need to do this or will they be able to keep the levels upstream managed sufficiently to stop it overtopping? Or will another pontoon be required at that side to raise the piling?
Good news elsewhere is that the works on the breach near Hack Green on the Shroppie are nearing completion, the area was being filled with water yesterday. Well done C&RT, just wish they had been as successful on the Aire and Calder.
*Post update Mark has been out again with his drone today. Good news is that the cofferdam has emptied itself again.
30/3/2021
There are more photos, so I’ll write more in the morning as it’s time for food now.
Well Canal and River Trust have been busy with notices. On the website yesterday they posted the following
Update 24/03/21
The Trust and its contractors are in the final stages of making the cofferdam watertight, to enable the cofferdam to be dewatered. We anticipate that our engineers will be able to carry out the first detailed inspection at the breach site shortly after Easter. Water levels continue to be carefully monitored. While passage through Goole Caission is not possible at present, the Trust is working hard to ensure boaters can once again pass between Pollington and Sykehouse Lock. We intend to operate this on a booking only basis from 12Â April (in line with the Government road map).
Certainly the levels in Goole were much better yesterday. But another ten days before engineers carry out a detailed inspection!
Then today notices regarding assisted passage have been coming through.
From the 12th of April access through Whitley Lock will be possible twice daily at 10am and 3pm.
From the 12th April, we shall be permitting a once a day access through Pollington Lock and Sykehouse Lock at 10am daily to allow boats to transit between Pollington Lock to Sykehouse Lock.
Mooring and overnight staying along sections between Pollington and Sykehouse Locks is not currently permitted.
Passage through these locks needs to be booked 48hrs in advance by calling 0303 0404040, Mon to Fri 9am – 5pm
Why assisted passage? Because they need to control the water levels in the pound where the breach is and should two locks full of water be let out at the same time, the wave created would likely overtop the cofferdam.
This is all very exciting. Except we still can’t get out from Goole!
A is Viking Marina B Ocean Lock onto the River Ouse
But should we be able to escape out onto the River Ouse we would be able to turn left and head up stream to Selby.
C Selby Lock
Turn in at Selby lock onto the Selby Canal.
D Tankards Bridge, E Beal Lock
You can only pass under Tankards Bridge, the last on the canal, if you are under 7ft high as currently scaffolding is being used to reinforce the parapet wall which suffered damage last September when a vehicle struck it. From there along the River Aire where a width restriction of 10ft 5″ is in place due to silt build up behind the lock gates. Thankfully neither of these would be a problem for us.
F Whitley Lock
Once up Bank Dole Lock we would re-join the Aire and Calder Navigation and turn left heading eastwards towards Goole. We’d be able to pass down Whitley Lock one morning.
G Pollington Lock, H Sykehouse Junction, I Sykehouse Lock. J The breach site
Then down Pollington Lock the following day, turn right onto the New Junction Canal and up Sykehouse Lock. Then and only then would we have successfully escaped!
According to Canal Plan if we did this route it would be 40 miles 1 furlong and 8 locks, normally taking 13hrs 45 minutes. But with current restrictions it would take us 3 days waiting for locks to open.
A Viking Marina, I Sykehouse Lock
Without the breach in our way Canal Plan has the more direct journey at 8 miles 3/4 furlong, 1 lock, taking us 2hrs 45 minutes.
Three Months ago today we learned of the breach on the Aire and Calder. The canal was doing a good job of emptying itself into fields, the flow of water heading for the villages of East and West Cowick. That all feels like a long time ago.
This morning my computer binged at me, a message from Mark Penn with new photos from the breach site. His initial comment was that there was no change. This was right in some respects, no progress on emptying out the cofferdam ready for inspection. But on the other hand there has been quite a bit happening.
20/3/21
Four days ago we received the notice from C&RT regarding a temporary fix to where the cofferdam meets the piling on the south eastern end. They would be implementing a more secure seal here, which is in progress and visible on Marks photos.
The first thing noticeable is that the floating pontoon is back on site. It had been stored through the other side of New Bridge. The pipes pumping water round the breach have been extended towards Goole, meaning that the pontoon and workers wouldn’t be drenched whilst working.
20-3-21
Water is actually being pumped into the cofferdam from the western end. This at first seems strange, pumping water in to where there is a breach, only for the water to flow out and into the drain below.
20-3-21
But thinking about it, it must be to help relieve pressure on the cofferdam whilst they make a more robust seal. We all know that lock gates open easily when the water level is equal at one end of the lock, yet the water pressure at the other end is immense. So keeping the water level between the cofferdam and the canal will mean less stress on what they are working on.
By the pontoon you can see a lot of new piling being put in along the bank where aggregate had been added last week. The void has been filled and now they are reinforcing the piling where it meets the cofferdam.
20-3-21
The above photo shows this better. A better fix than some blue tarpaulin and a roll of gaffa tape would do!
20-3-21
From above you can see the new piling lines up with the dam and the aggregate. Here’s hoping that this fix is nearing completion and that no more voids will hold up the cofferdam from being pumped out fully next week. Then the investigations can start and the engineers can get to work on a solution.
20-3-21 A boom has been positioned downstream near the bridge
A year ago we had arrived in Nantwich to stock up before continuing northwards. Little did we know we’d be there for months. The world was a different place, everyone getting used to what social distancing was, panic buying and hand sanitizer were new things. Supermarket shelves were empty and queues were long.
Tomorrow, Saturday, we’d have our first Geraghty Zoom.
21/3/2020
In all our minds back then we knew lockdown was coming, but only imagined it would last for a few months. Then life would return to some form of normality. Kath, Micks sister had left a plant on her office desk hoping it might survive, she’s not been back.
Theatres closed their doors on the 16th March 2020. A year later it was apt to have a panto meeting. Showing my white card model to the creative team and producers was a little strange on a Zoom meeting. Mick had enabled my phone to be an extra camera so that I could show people round my model whilst giving them motion sickness! A good meeting.
Muddy Cows
On Wednesday I caught a bus up to Scarborough Rugby Club where I joined the queue for the local vaccination centre. I’d last stepped foot in this building eight years ago when collecting old rugby shirts to be used in the premier production of John Godbers Muddy Cows at the SJT.
SRUFC Vaccination Centre
This time I left with my vaccination card and a sticker. My photo on social media has caused some unrest from those who didn’t receive one. Mick is miffed and so is Kath from Herbie along with numerous friends. Sorry!
This morning I have received my NHS vaccination letter, I’m glad my doctors had everything in hand as the nearest hub to us is Saltburn 31 miles away. The 3.5 miles on the old railway line is much better. Just a shame I’ve had a few side effects, hopefully todays vertigo will pass soon.
0 locks, 0 miles, 1 dam filling up, 1 reinforced joint, 2 boaters still with fingers crossed, 3 months, 53rd Geraghty zoom, 1:25 scale white card model, 18 rugby shirts, 1 jab, 3.5 miles home, 1 sticker controversy, 1 wild flower bed planted, 6 more houses to go, 2 thank you’s to Paul (Waterway Routes) and Dave Scouts for blog advice, 1 map from last year to check it still works, 1 window open all sunny day for Tilly, 1 Mrs Tilly stamp of approval.
This morning we woke to an update regarding the breach from C&RT.
Update on 16/03/2021:
The downstream seal of the cofferdam has been fixed temporarily with downstream water levels stabilising. A robust fix is currently being implemented to secure the seal.
Dewatering of the cofferdam is now programmed for week commencing 22nd March with breach investigations to follow.
15-3-21
Mark went back to the site yesterday. Plenty of vehicles about the place and a delivery of diesel for the generators looked like it was happening.
15-3-21 Wonder when the crops will start to show themselves
Some of the new pumps look like they might be adding to the water levels.
The level on the downstream end is certainly higher. It is helping to keep the cofferdam topped up again too.
15-3-21
It may be possible to raise the piling here to help keep the water out of the breach along with keeping the levels higher towards the docks.
Obviously water is still draining out of the cofferdam into the drain below.
15-3-21
This photo I find the most interesting. Just above the blue tarpaulin, on the left hand side, is the hole in the grass that has been visible from early on. This at one time had been filled with aggregate. But working left from here, along the piling edge, it looks like there are three more holes as the canal widens out.
It’s been almost three months since the breach happened. Here’s hoping that the cofferdam does get drained next week and that there are no more hold ups. Then the engineers will be able to assess what will be needed for a permanent fix.
Thank you for the comments about our move. It does seem that other peoples blog rolls are not showing our latest posts though and at the moment I’m having difficulty seeing statistics regarding views, maybe I’m just looking in the wrong place. You know how I like numbers!
Thank you Mark for the photos again and thank you Mick for sorting the blog.
The recent storm has stopped Mark from flying his drone recently, but this morning he deemed the wind speed was just about okay to go flying again.
14/3/2021
The cofferdam looks like it has drained by itself again, although maybe not quite as low as it has done before.
The pictures today show where the leek happened that has now been mended.
25/2/2021
25/2/2021
These photos are from 25th February. In the bottom right hand corner where the pipes gently curve away from the bank there is a grassy gap showing where the cofferdam piling meets the existing piling and there is a bridge over the pump pipes.
7/3/2021
Then these from the 7th March. The area is much darker than before, this is because there is a hole there.
7/3/2021
It looks like you can see the back of the bank piling and then another layer of piling is close up to the pipes, you can see the corrugations in this second photo.
14/3/2021
Today the hole has now been filled with aggregate, the chalky surface quite obvious and there may also be more clay than before by the cofferdam piling.
14/3/2021
The second raft for the pumps to extract more water (at the western side) have been plumbed in, but there are no extra pipes at the eastern end.
14/3/2021
The level between the breach and Goole caisson is being kept about a foot lower than normal so that the level doesn’t over top the cofferdam. The removal of the top section of stop planks helps with this, draining any excess water that is pumped round the breach into the docks to help keep the level up there.
At some point this week we will be changing our website hosting. Readers shouldn’t notice anything different and those who get an email each time I post should still get one. I will do my best to inform you of the last post before we move, JUST IN CASE!
Where were we
2020. Betton Wood Bridge, Shropshire Union Canal. LINK
In my last post I got distracted by the blue tarpaulin at the western end of the cofferdam. I’m still not sure why this is there but a comment from David has confirmed that the leak last week, that filled the cofferdam up was at the eastern end. A void adjacent to the eastern end of the piling, on the south bank, allowed water to fill the dam back up. This was mended, but there seems there must be another leak somewhere as the cofferdam is still quite full, well it was a couple of days ago.
The extra raft at the western end is also most likely to increase the amount of water being pumped round the site, trying to keep up with water that is used at the docks.
It is thought that there are voids and leaks all along the aqueduct on the north bank, so not just one hole. The extent of these won’t be known until the cofferdam is fully drained. At the moment the best case scenario is that the canal will be closed for a couple of months, worst case until the end of the summer. But until the engineers can get a better look they obviously can’t really say.
It’s been two months since we last checked on Oleanna ourselves, others are doing a great job of checking her ropes when the levels alter, but today we paid an essential visit to her. Our Boat safety is booked soon and we knew of a few jobs that needed doing before hand.
Mick picked a hire car up from Beerhouse who are working out cheaper than Enterprise at the moment, £10 cheaper if you call them rather than booking online too. Not a pristine car, bumps and scrapes, but we weren’t bothered.
The trip over the Wolds was lovely, snowdrops filling the verges and reaching up into the woods. Daffodil leaves stretching up towards the sky, hopefully they will be in bloom the next time we do this drive, some of the roundabouts are spectacular.
Spring spinging
The level in the docks still isn’t what it was when we first arrived in September, but today Oleanna was certainly afloat and not sat on the bottom. It was a big step down, no need for the booster block though.
Masked up we went to check in with Laird at the marina. No new news regarding the breach and our only possible escape route would be if we dig a tunnel.
Then it was time to get on with jobs.
A kitchen shelf made to measure, it just needs an extension for the starter battery
The battery terminals needed some form of covering, this is so that you can’t drop any tools on them. A piece of wood would do the job. An unused shelf from a kitchen cupboard had been brought with us. This proved to be the right size for the leisure batteries, but the starter still needs something. We took measurements and will look for either a piece just for the starter, or see if we have a slightly longer shelf that would cover all batteries in one go.
Mick started her up, first time, no grumbling. She was left to run, the leisure batteries already at 100% from the solar, but the bow thruster battery could do with a charge.
I measured up the poppers on the front door blinds. One is broken so needs replacing and I’m wanting to make us two new blinds for when the original ones get too tatty, due to our second mate! The poppers appear to be 12mm diameter, so I’ll need the press stud side and a die to fix them to the cloth. I’m hoping a costume friend may just have what I need to do this.
3003
The red grabrails are all looking very faded, apart from where I touched them up recently. Somehow the red mentioned in the boat bible isn’t the correct colour, but when we were last in Sheffield the painter there gave me a tin of the right colour. I’m wanting to get a new tin to have enough to do all the grabrail, plus this tin reacted strangely when applied.
Cratch rolled up
One place the Boat Safety will need to get to is the gas locker in the bow. Oleanna is on a short pontoon, moored stern in, so not the easiest place to get to. So next job was to wind. We’d chosen today to do this so as to avoid a named storm that is due tomorrow.
Untying all the ropes holding Oleanna to the pontoon took quite some time. The fender eyes on the gunnels are useful in such situations, but really awkward to get to when your boat is lower than the pontoon. Mick had to lie down and then lean over the edge to feed ropes back through the eyes. I could reach the bow rope from the cratch, but this took quite some feeding too.
Reversing
With the cratch cover rolled up both sides and the pram cover lowered we were ready to move her for the first time in six months. No chance of pushing off, she just drifted away from the pontoon and we were off!
Even though all we were doing was winding, just standing at the back felt good. The lady from the Dutch Barge two boats over waved to us as we pulled out of our mooring.
Winding in a marina can be dodgy. Usually the wind will pick up as soon as you want to turn and you end up being pushed towards lines of moored boats. We once got to meet a whole new section of boaters at Crick Marina doing this, everyone trying to give you a push in the right direction away from their boats!
A different view
Marinas have people who watch and the space required to manoeuvre is never luxurious, so the odds are always stacked against you. Mick brought Oleanna out, turned her into the gap almost opposite, then swung the stern round. A touch of bow thruster whist turning meant we kept away from other boats. Reverse, forwards, reverse and then an extra boost of power to finish the turn and we’d finished our handbrake turn and headed back to our mooring.
Only five minutes until we were back tied up, facing the other way. Then the rope tying started again, leaving enough slack we hope for varying levels, but tight enough that she won’t be blown all over the shop in the next storm. The plank that had been positioned to stop us drifting under the pontoon was leaned over a touch. The corner of the pontoon could possibly just catch the gunnel if the levels came back up. A Tilly fender was also added into the equation.
Labelled up, another on the door
After eating our pack up the next job was the fire extinguishers. Oleanna has three. The ones at the stern and bow are both in cupboards. When they were fitted we were warned that we’d need to label the cupboards for the boat safety. So big labels went inside the cupboards and smaller ones on the outside. Each fire extinguisher was turned upside down a few times before going back into position.
The third one has for sometime lived in the gap between the shower and bathroom door. This means it is near the centre of the boat, close to the multi-fuel stove and not in the way. We’d never got round to fixing it to the wall.
A quick check with our Bubble Carpenter Frank as we’d be screwing into laminate. Franks final words were ‘don’t mess it up!’ Small pilot holes were followed by slightly bigger ones then the bracket was screwed into position. Job done and not messed up.
Tilly’s paws absent
The CO alarms and heat sensors have all had their batteries removed whilst we’ve been off the boat, saves some poor neighbour having to live with a dying battery and the beep that accompanies it. Each detector was checked in turn and then the batteries removed again, these will go back in on the day of the test.
We might wash the ropes
After six months of sitting still Oleanna is showing it a touch, both inside and out. All the ropes are turning green, the cratch and pram cover could do with another spray of Wet and Forget. Inside the bathroom windows have been left ajar, the plastic frames now covered in a thick layer of dustyness. These got a good clean, sadly my faithful assistant wasn’t on hand to inspect them from the outside, leaving her stamp of approval on newly cleaned glass!
If only Oleanna 25 times bigger was so quick to clean
A sweep through and a tidy in the galley. The wine cellar emptied of the bottles we’d stocked up on for Christmas, this gives access to the Alde Boiler. Jobs done, just a couple of things to sort on the morning of the inspection.
Hello
Mick had chance to have a chat with Geoff. We’d been hoping to see if anyone else was plotting an escape. Apparently someone had approached either ABP (who run the docks) or C&RT to see if it would be possible to use the lock out onto the Ouse if half a dozen boats got together to share. Sadly this will not be allowed. So currently the only way out of Goole is on the back of a lorry.
Looking back towards the docks
Before heading for the house we turned left out of the marina and drove down to look at the caisson. Lisa had mentioned that the top metal stop plank had been removed the other weekend and that the gates had been opened.
Gates open a bit at the caisson
The area has had a tidy up since we first came to have a look back in December and sure enough the caisson gates are open a bit, red lights indicate that the navigation is closed and you certainly wouldn’t get a boat through the gap.
Across on the southern bank the top stop plank lay. Not just a foot/eighteen inches deep but around three foot. All the pumps and pipes have gone from here, most probably to the breach site.
The water in the docks was slightly lower than that in the cut, causing there to be a flow over the rest of the stop planks. I suspect the remaining planks are being left in to protect both the docks and the cut. Should the level drop on one side, there is still something to hold back the water. So unless a lot more water gets pumped round the breach site, Oleanna is likely to be at her highest right now.
Looking towards the breach 4 miles away
Here’s hoping the cofferdam can be emptied and work of a solution started soon.
No going anywhere
Back at the house Tilly was waiting in a window for us. Her plight of cat food pouches having hit the main stream media after she’d brought the situation to their attention this morning. Apparently the shortage is due to the increase in pet ownership during lockdown and pet food manufacturers are finding it hard to ramp up production to keep up with demand. Don’t worry Tilly you’ve still got another 60 pouches to go before we have a problem!
0 locks, 100 meters, 1 wind, 2 girlie button presses, 3 extinguishers, 5 signs, 1 piece of wood, 1 more needed, 3 down to 2, 1 water tank almost empty, 12mm popper, 3003, 1 plank jauntified, 2 tyre fenders, 2 ham butties, 0 milk, 3ft stop plank, 1 red light, 0 escape, 2 thank yous to David and Stuart, 1 cat staying out of the media hype, 2 months of pouches, 1 blog with all photos again.
Later this month we will be changing our website hosting. Readers shouldn’t notice anything different and those who get an email each time I post should still get one. I will do my best to inform you of the last post before we move, JUST IN CASE!
Mark has been back to the breach site this morning.
As reported the level is up in the cofferdam again.
From C&RTs update it sounded like the eastern/downstream end of the cofferdam had given way. But from this photo it suggests it was actually the western/upstream end as a blue tarp has been added where the piling meets the bank.
Where the pipes pump the water out from the western end (I don’t know what to call them) another raft has appeared. It looks like they are planning on extending the existing pipes to this new raft, so as to suck water out further away from the piling. Maybe this is what caused the problem.
Down in the drain below you can see water is escaping again. This suggests that the hole is in the side not the base of this section. The water drained down to a level last time and then was needing pumps to completely empty the cofferdam.
The water level is now higher therefore draining into the drain again. I wonder how long it takes for it to empty itself?
These two photos were taken about ten days ago when the level was lower. The blue tarp and bags of aggregate still in position from before Christmas, helping to stem the flow of water.
Here you can see the water is being pumped out from the drain into the Dutch River.
This was the caisson gates and stop planks at Goole a couple of weeks ago, pumps working hard there.
Viking Marina at the same time. Hello Oleanna!
Goole Boathouse Marina
Thank you once again to Mark for the great photos. Even though there have been problems at the site it is good to see how things are first hand.
Later this month we will be changing our website hosting. Readers shouldn’t notice anything different and those who get an email each time I post should still get one. I will do my best to inform you of the last post before we move, JUST IN CASE!
Thank you Mike from Alchemy for bringing the notice below to our attention last night. Stoppage notices go to Mick and he hadn’t checked his emails for a while.
Notice Alert
Aire & Calder Navigation Main Line Location: Goole Docks Starts At: Goole Visitor Moorings Ends At: Goole Visitor Moorings
Friday 5 March 2021 16:15 until further notice
Type: Advice Reason: Information
Original message:
Skippers of all craft are advised that due to restricted water levels caused by the breach at New Bridge on the Aire & Calder Navigation Associated British Ports (ABP) are restricting passage at Ocean Lock Goole to commercial use only for the foreseeable future. Skippers of all craft are advise to bear this in mind when planning passage on the Derwent, Ouse, Humber, Trent and other connecting waterways.
This notice means that our escape route is now blocked. We always knew this was a possibility and sadly it is now a reality. Currently our only way out from Goole is on the back of a lorry.
Our hoped for departure date is still a way off, so there is still chance that the situation may change. But our giddiness of last week has been dampened somewhat!
Yesterday levels in the docks were low again. Apparently water had been flowing over the stop planks at the caisson last weekend, the top plank having been removed. Maybe this was because the eastern/downstream side of the cofferdam had water overflowing it.
Thank you Don for the link to this footage taken last Sunday. The cofferdam filling back up nicely. Mark Penn had also reported a week earlier that the level on the western/upstream side had been doing similar.
I’ve just noticed that C&RT have also updated their website with the following. It explains what has been happening in better detail than the snippets we’ve been getting on stoppage notices. Information is better than speculation.
Update 05/03/2021
Our initial actions when the breach occurred on the 20Â December were to make the site safe and prevent further release of water from the canal which would have caused further issues for both boaters and local residents. We managed to make the site safe within a few days and added to these temporary measures over the next few weeks to stabilise the repair.
Since that point, our efforts have focussed on managing water levels for boats whilst preparing for the permanent works. We closed Goole caission and pumped water into Goole Dock and although this helped to some extent it proved challenging. This could be because there is a leak in the dock or it could be because there is a problem with the caisson or even a combination of the two.
In order to both see the damage to the bed of the canal and provide working space for a temporary repair we then installed a cofferdam and this was completed towards the end of February. This is essentially two lines of sheet piles across the canal with pumps in place to send the water across the piles.
Once these pumps were in place, to provide a continuity of water, Â we were able to take the water out of the cofferdam and start our inspection. Unfortunately the bank on the south side of the canal, where the piles of the cofferdam nearest the dock connected to it, suffered damage and so the cofferdam started to fill up again. We have almost completed the repair of this damage and can start to take the water out of the cofferdam again.
All these challenges have made it difficult to maintain a steady water level but we can assure you we are doing all we can to ensure this is the case.
At this stage our engineers estimate the permanent repair project will take several months to complete, though as we learn more about the cause of the problem, we will be able to refine this estimate. Until complete the navigation will unfortunately be closed at the breach site.
We apologise for the effects of the breach on the Aire & Calder and we appreciate how frustrating this must be. Please be assured we are doing all we can to resolve this problem.
A problem with the seal at the breach site has resulted in an inflow of water from the downstream end that our contractors are currently attending to.
Downstream water level fluctuations are expected to continue whilst this is addressed, and further dewatering of the breach site is planned for w/c 8th March 2021.
Maybe they’ve been waiting to see how the cofferdam would hold up before fully dewatering the breach site. Maybe the chap who reported the cofferdam being full again earlier this week was correct.
Meanwhile here in Scarborough a folding crate has been brought back out of storage and items that need to head back to Oleanna are gradually being added. We have a boat safety inspection booked in a few weeks time, before this we need to do a couple of jobs onboard. Here’s hoping we don’t have to clamber down off the pontoon again to get onboard.
