Another brief plug for the Greenbook WWW site, I'm afraid: they are hosting a survey on what areas of the Broads need dredging. The information will go to the Broads Authority to help them plan their river works. If you've gone aground recently where you didn't expect to - or you know of other areas where the bottom is getting too close to the top, it's worth going to http://www.thegreenbook.org.uk and filling in the survey form.

The only place I have ever gone aground in either sailing or motor boats is in my own boat dock. Somehow I think I am going to have to dredge that myself.

Then you're very lucky! I went aground four times in one race on the Yare a couple of weeks ago. But it was an extremely low tide. And after the first time, I should have known to keep away from the bank.

Not exactly on topic, but one year a very low tide completely drained the basin at Beaver Fleet's yard at St.Olaves - luckily the yard staff warned us to get out on to the river before it happened!

You should be ok on Rockland now - touch wood - it's been dredged and the channels re-buoyed. (Was your problem recent?)

But a lot of people are concerned about other areas - such as the lower Bure and Oulton Broad.

Hi Merganser with out getting into a  debate this dredging thing has me confused with all the different Boards involved, all any of us boaters want is to navigate the waterways your input will be wellcome.cheers for now.

Ok - the position is that Trudi Wakelin, the Rivers Engineer at the Broads Authority, is currently developing a policy with regard to dredging (they approach it from the other direction and call it a "siltation strategy.")

The point is that resources for dredging are obviously not infinite. To get the best value for money from what they can afford to do, they are trying to establish what causes siltation in certain areas (the causes differ from place to place), whether any methods can be developed to stop the siltation happening - and where it can't, they are trying to work out how much dredging is required, at what frequency, to what depth etc. As part of this research, they are trying to establish - using information from boat users - where siltation has become a problem.

For example: many people agree that the lower Bure is now "a problem". But regular boat users have treated that section of river with caution for many years - particularly at low tide, particularly close to the banks. The BA needs to know if and where the problem has got worse. Hopefully, they'll then be able to do something about it.

At the moment, I don't think there is an agreed standard as to what constitutes sufficient depth. Is the same depth required all over the Broads? In the past, the Yare was maintained at a greater depth than other sections, because commercial, marine traffic (real ships!) used to use it. That has mostly gone away - but does the Yare still need to be deeper than other rivers? After all, the biggest sea going yachts and motor-cruisers are confined to the Yare. And do large motor cruisers with twin screws need deeper water closer to the edge? But boats like that are not likely to go up the Ant (unless you know better...)

So optimum minimum depth is related to usage. Another example of this is Hickling. The whole Broad is a navigation, not just the channel. But for decades, the largest river cruiser class yachts have not attempted to race all over it, because they knew they would grind to a halt. On the other hand, they have all expected to be able to race all over Oulton at any state of the tide. It seems that is no longer possible. So does that make Oulton a priority? (I would have thought it does).

A related problem is tree coverage. Are we losing navigable water space because trees are overgrowing the channel? If you know somewhere where that is happening, it's worth putting that information into the survey form as well.

I could ramble on, but I hope that gives you a general idea of the sort of information to BA is trying to collect.

Dear Merganser

Thank you very much for your well informed reply.  I am not quite sure I understand all of it, but if indeed you are really helping to keep our waterways open for navigation that's fine.

I wish you well in the future for all your efforts.

Cheers

Roya

Please have a happy Christmas (We are actually boating on the Broads this Christmas and hope we do not go aground).
