Good evening,

Just the one question from me this time JP. Its a question I have failed to get an answer to for some years now so I figure ask at the top once again and see what happens...

What constitutes 'navigation'?

The BA is required to maintain navigation, that is not in dispute, but what is 'navigation'?

To maintain water depths at a level which allows the scouts to float their canoe's would still allow navigation but not at a depth needed by the majority of broads users.

Is 'navigation' deemed to be a depth of 3ft, 6ft, or maybe just 6 inches?

So here is my question... What water depth does the BA consider to be reasonable to maintain navigation?

Once we have that established we can all work towards it eh?


If I am a "woody" how come there are no "fibreglassy's" "plasticy's" or "steelies"?

Good Evening JanetAnne,

Thanks for the question.

The Authority’s functions in respect of maintaining the navigation area are set out in the Norfolk and Suffolk Broads Act 1988 S10 (1).

(1)The Authority shall—

(a) maintain the navigation area for the purposes of navigation to such standard as appears to it to be reasonably required; and

(b) take such steps to improve and develop it as it thinks fit.

This requires the Authority to exercise its judgment.

The navigation area is defined in Section 8 of the Act as:

1) In this Act “the navigation area” means, subject to any variation for the time being in force by virtue of an order under subsection (3) below—

(a) those stretches of the rivers Bure, Yare and Waveney, and their tributaries, branches and embayments (including Oulton Broad) which, at the passing of this Act, were in use for navigation by virtue of any public right of navigation;

(b) the banks of the waterways which make up those stretches; and

(c) Haddiscoe New Cut and its banks;

(d) Breydon Water and the Lower Bure.

The Authority’s Sediment Management Strategy 2007 sets out the ‘ideal waterway specifications’ in terms of depths. These vary across the network from 1.5 metres to 2.4 metres below mean low water springs.

You can find a copy of the Strategy on the Authority’s website with the maps showing both the waterway specifications and recent hydrographic survey information.

The report is at the following link:

http://www.broads-authority.gov.uk/boating/navigating-the-broads/water-depths

Hope that helps – please come back to me if you want any further information.

Regards

John

1.5m below mean low water eh?

My yacht must have grown a longer keel then because it keeps running aground.

I shall study your document with much interest.

I know JP has left the discussion for now, but I have just looked at the depth map for the Upper Thurne (Martham to West Somerton)
BA Map
This is an area where I have had several experiences of boats being stuck mid-channel.  BA's own map shows most of the section less than 1.5m depth, with quite a lot of it in the '0.5 to 1.0' category  -  especially across Martham Broad and into the public moorings at West Somerton.  Well, actually, I didn't need a map to tell me those bits were very shallow.

It's a shame I'm too late, but I'd have loved to ask JP a subsidiary question :  'When will this reach be dredged?'

Jeremy-Aslan, it's not just water depth that affects the ability to navigate. Crome's Dyke is deep enough for most Broads craft to navigate, but the reed encroachment on the bank owned by the BA, and the tree overhang on the side managed by Catfield Parish Council, are such as to reduce the available navigable width so much as to prevent anything but a canoe or rowing boat to use it. The PC cannot afford to cut the trees back and the BA refuse to.

Dear Jeremy-Aslan

The Thurne does get shallow, particularly upstream of Dungeons Corner.  There are however a number of navigation areas across the Upper Thurne that need to be dredged and we therefore have to prioritise.

Due to the designations and sensitivities of the Upper Thurne any dredging work takes a great deal of careful planning and management that said we have delivered five dredging projects there since 2010.

The focus so far has been on Heigham Sound and Hickling Broad, as these have been deemed as a higher priority particularly due to the level of boat use and reported incidents.

Over the next three years we have further work planned on Hickling Broad and we are considering feasible options for work on Waxham Cut and Catfield Dyke.

We will take in to consideration your comments on groundings on the approach to West Somerton and look into possible solutions; however this stretch of the Thurne is not likely to feature on our dredging programme in the next three years.

Regards

John

Thank you for replying, although I can't pretend that I like the answer.  

The last time that I was at West Somerton (in April 2016) with a group of yachts we had three in succession very firmly aground in the middle of the channel near the end of the piled bank on the south side.  It took a huge amount of heaving on ropes from many people on the bank to get each one out.  Two of them subsequently went aground (again, mid-channel) trying to cross Martham Broad  -  but then, the BA's own depth survey shows that such an occurrence is likely.  As far as our group is concerned, the reach to West Somerton has been allowed by the B.A. to be 'closed to navigation'  -  which is far from ideal.  Therefore, we are no longer able to moor there, which is most inconvenient for us.  For our group, 'no plans in the next three years' is extremely depressing news.

I filled in the on-line form for Broads Control, but never had any contact from B.A.  -  no automatic confirmation that my complaint had been received, no follow-up communication asking for further details or to advise when the problem may be rectified.

Of course, the dredging in Heigham Sound is most welcome  -  I've towed yachts off the mud in the middle of there before now, and it seems much better.

However, last winter there was a huge amount of dredging plant sitting at Martham Boatyard, apparently waiting for the water temperature to be cold enough for dredging to start on Hickling Broad.  Surely, it could have been put to use in the meantime to clear some of the shallowest bits of the nearby reach to West Somerton?

Well next April we shall not be paying a toll for our yacht. It has been stuck in Catfield Dyke for two seasons now, in fact this year we never bothered to rig it and it hasn't left the mooring - no point, it wont get out the dyke.

Instead, I shall offer to tax it with the DVLA because thats the only way its ever going to get out of there... by road!

And now they want another three years to get around to dredging it. Grrr


Maintaining navigation my *rs*!!!

If I am a "woody" how come there are no "fibreglassy's" "plasticy's" or "steelies"?
