Waterways World

We happily subscribe to Waterways World and love the Pull-Out Guides for the regions. This month (February 2013) we have more interest than usual because there are two articles on our boating area: one describes the "Cruise of a Lifetime" - 344 miles from Llangollen to the Little Ouse - and a guide to the Middle Levels.
The long cruise starts in Wales and makes its way across England to the river Nene (where we are now) describing the experience as "drifting timelessly through rural middle England, past quaint stone-built villages and historic watermills". Oundle (our mooring) is "the icing on the sumptuous Nene cake". So we look forward to the boating season with additional rose tinted glasses - but actually, it's true!
The Middle Levels are said to be: "remote adventurous cruising" and more than just a transit route between the Ouse and the Nene. Indeed this is what we found. It also describes the problems of weed clogging the prop, which we experienced in 2012, to our great frustration.
See our earlier blogs for example here for the Nene and here for the Middle Levels as we saw them.
Oh, and one other reason for enjoying the article on the  west to east trip across England - it ends with a lovely pic of Patience in front of Kings College Chapel, taken by David Coppendale when we navigated the Cam in 2011.
So here's another glimpse of that trip along The Backs of the colleges in Cambridge. One of the blog entries for that trip is here. We recommend the eastern region, Nene, Middle and Great Ouse!

Truly Awash

Boating in 2012 was a trial, with drought up to March and flood thereafter. There are too many blog entries here called "Awash" and "Nene Floods" for my liking!
There's an excellent page from the BBC here showing the rainfall stats and musing on the climate. 
They do rather better than the Met Office to put across complex data for public consumption.
A nostalgic look back on our floods in the eastern region takes me to

November 22nd and pretty well every entry in November!
 Actually it looks as if we did nothing but moan about rain all year!
Here's to a brighter 2013.

Nene Floods 4

According to the Environment Agency monitoring station at Lilford (just upstream from Oundle Marina), the river reached its highest point on the evening of Sunday 25th November. These photos were taken on the morning of 26th November and show the water covering the mooring pontoons, the bank and the car park at the marina. Mark, the Marina Manager, and his colleagues had been working hard overnight to check that all the boats were safe and slackening mooring lines, where necessary, under very difficult conditions.  When I called in again on the afternoon of Friday 30th November, the water had receded to almost normal and again the marina people had been checking that boats weren't hung up on pontoons, etc as the level went down.  Their hard work is really appreciated.  Many thanks!

The Oundle Mill Restaurant at Upper Barnwell lock wasn't so fortunate. It was completely flooded out and we feel really sorry for the owners, who had recently put so much time and money into restoring it. This photo (also taken on the 26th) shows the mill isolated in the middle of the river, which can also be seen cascading over the lock gates.  The relief channel, which bypasses the Upper and Lower Barnwell locks, just couldn't take all the flow and had burst its banks where it flows under the old stone bridge on the road into town, as can be seen in the last photo.

Nene Floods 3

Many readers of this blog will be most interested in canals and narrow boats, but the rivers also need some explaining.
Coming as we do from East Anglia, Patience has spent her recent years on the Ouse and tributaries and now the Nene (via the Middle Level). These river systems are not just for leisure boating but are primarily for water control. That's why they are managed by the Environment Agency rather than British Waterways / Canal River Trust.

Car Park, Godmanchester

This pic was taken in my office gardens in 2009 but the scene is the same today - except that there are gangs of men wandering around looking lost. The reason? They're building flood defences in the gardens bordering the river, but the floods have over-run their site, so flood barrier building has come to a halt. Halted by floods ....

You can visualise the north-south Grand Union Canal west of Northampton on the left, the Ouse on the right and the Nene and Middle Levels in the centre connecting the two sides.

The Northampton Arm leaves the Grand Union Canal at Gayton Junction and joins the River Nene in the centre of Northampton.

The River Nene then takes a twisting and attractive rural route through Oundle where we are moored and Lilford, our nearest EA measuring station, to Peterborough's Stanground Lock where it divides, with the northern channel becoming tidal as it crosses the flat Fenlands on its way to the sea. For preference, most boaters avoid the difficult tidal stretch and enter the quiet and often narrow Middle Levels.

The Middle Levels are primarily a network of rivers, man-made drainage ditches and sluices intended to drain the low-lying area between Peterborough and Ely. They also offer a navigable route between the River Nene and the Ouse.

Nearly all the locks on the Nene have conventional mitre gates at the upstream end and a single vertically lifting guillotine gate at the downstream end. This means the locks can be used as additional weirs in time of flood, when the mitre gates are chained open and the guillotines lifted to allow the water to flow straight through. No navigation is allowed at these times.

So because in high water times the Nene is used to channel excess water out to sea, boaters must stay away - or else! The flooding that we see in some places such as Port Holme and the Ouse Washes is the planned flooding of low lying areas designed for this. The flooding of low lying houses built on the flood plains is an inevitable consequence of allowing inappropriate building. With an increase in serious weather events that can only get worse.
So the moral is, move your home up hill and leave your boat in a safe and caring marina, like ours, or you could find your house under water and your boat stranded in a field!
Either way, don't blame the EA if they prioritise drainage solutions above recreational boating....

Mooring at Thrapston Bridge on the Nene, November 25th 2012

Patience moored at Thrapston Bridge on the Nene, September 20th 2012

So thanks again to Oundle Marina for looking after Patience!

Nene Floods 2

Driving through Cambridge at Fen Causeway and also across Port Holme at Huntingdon I see a lot of water, but John alerts me to the floods which are hitting the Nene in a big way!
The EA is recording near record heights at Lilford tonight, November 25th:

and at Oundle Marina staff have closed the chandlery and are going around checking moorings.

MARINA NEWS

Sunday 25th November. The water is very high in the marina and moorers may not be able to get to their boats. The staff & Environment Agency are out making sure that boats are not tied up too tightly. If you are coming to the marina today please do not put yourself or anyone else in danger.

We'll be OK at our pontoon in a safe basin, but how would you feel if you'd tried to save a few quid by leaving your boat at some godforsaken spot on the river?
This is Tewkesbury in 2007. From the M5 we clearly saw boats  of all kinds washed up and subsequently stranded on fields bordering the river at Tewkesbury.

Tanks and tappets

With moderately fine weather first thing, we motored over to Oundle marina to do a few more winterising tasks.  The diesel tank was topped up to reduce the likelihood of condensation over the winter.  We were reassured by Mark in the office that he pre-treats all the marina biodiesel, so we don't have to worry about any additives.  In the short journey to the fueling stage we managed to pick up a short length of rope (someone else's) around the prop shaft, although it didn't seem to slow Patience down too much.  We also noted that the o-ring on the filler cap needs replacing, so it was measured up to get a replacement.

Having returned to our mooring, it was off with the rocker cover to check the valve clearances.  According to the BMC manual. 1.8 litre engines with a 'later type' camshaft should run with a clearance of 0.014 in, measured hot or cold.  You can tell if you have a later type camshaft by looking at the side of the lower engine block - if it has ribs you have the later type camshaft.  Turning over the diesel engine to close each of the valves in turn is difficult, as the gearbox doesn't engage if there is no hydraulic pressure and you can't apply enough torque on the nut on the front end of the crankshaft to turn it.  In the end, we turned the engine over briefly on the starter and tried to avoid it firing.  Note for next time: this would be easier with the engine cold so that it doesn't fire. Most of the clearances seemed to be fine, but three needed adjusting to reduce the clearance to the designated 0.014 in.

We checked the gas fridge, which had been giving problems failing to ignite in the summer, but today seemed to fire up first time.  That may be because it's much easier to see the pilot light in the gloom of a winter's afternoon. We don't want to spend £500 or more on a new fridge if we can avoid it.

Finally, we measured up the effluent tank as a prelude to possibly investing in a resistance type depth gauge.  It's the one tank on board where a little technology would pay dividends.  Unlike the fresh water tank (which you can see into) and the fuel tank (which you can put a dipstick into), those solutions aren't a pleasant option for the black water tank!

Nene Floods

Popping across to care for Patience (see next blog) it became clear that there's an awful lot of water in the rivers around here.
At Huntingdon, Port Holme was awash and the race course was also flooded.
First the road leading to Oundle was partly flooded, then passing Barnwell Upper Lock we noticed water was pouring fiercely over the lock gates.

Further on, the marina levels were higher than usual but under the bridge at Oundle the river had burst its banks and was belting along at a great rate.
So once more, thank you The Environment Agency's  Floodline, with your warning:
Strong Stream Advice has been issued for the River Nene. Several locks on the River Nene are closed to navigation and are being used to discharge flood waters.

The Environment Agency strongly advises against attempting to boat on the River Nene. River flows are above normal and head-room at some sites will be restricted.
And thanks for your flood maps ...

... some of which are clearer than others!
