Flood warnings as well!

[Cantata]

A bit historical, but SYH website have got round to a report on the night's events on their website:

http://www.syharbour.co.uk/index.php?option=com_content&task=view&id=384&Itemid=1

The place was lit up like a football pitch all night and boy was it flooded. SYH wants to keep this quiet as they are seeking permission to dump dredge material on the area between the harbour and the Loom Pit. They have now been granted that permission so next time there will be a whole lot more water looking for a home. Jonathan must have been with Volunteer long before the surge and I certainly didn't see anything of him and his merry men when I went down for a shufti.

I don't understand the point of your post. If you dig from under water in one place and dump it under water a few hundred yards away it will make no difference to overall water levels at all.

What about HH dredging & deposition the spoil upriver between No 1 & Collimer

Well that makes a difference to the depth you can sail in, because of where they dumped it, and they should be ashamed. What the OP is on about is dredging in one place and dumping nearby raises the water levels. Ain't so, is it?

I am fully aware of what to OPs assumption is & he is incorrect.
I see little point in dredging only to deposit the spoil upriver only to allow the tidal flow to eventually bring all it back.

This is only done to appease the tree huggers

You're probably right, and getting a 'licence' to dredge is a nightmare now and is set to get worse as the MMO get their hands on it.

Would it be correct to say that the spoil comes originally from the land ?, in which case surely they could justify returning it ?
I can think of a few places that could do with extra soil on top of them

The HHA just return it to the shallows outside of the bouyed channel

Are you trying to put the Dredging Co out of business? They dump it up the Stour as well, seems crazy to me, but I think they are noy allowed to dump at the spoil ground anymore, because the silt gets in the fishes eyes or something.

The tree huggers want to keep the silt,worms ect within the river. The Orwell & Stour will end up line Southwold

SYH is built on the river bed. The river bed was built up there with fly ash from the power station, household rubbish and builders debris. Even the old chandelry finished up in the river. Now the massive mound of muck that was removed to make the harbour is on the move and leaching into the harbour just around where the light ship is and of course silt is brought in by the tide and visiting boats which is why it has to be dredged every year. They have made huge mud banks just outside the harbour where you will easily go aground if you try sailing on the landside of the line of boats. Four years ago this was possible with a metre keel, now it is dodgy at low water and I doubt they will be able to dump anymore there so it is to be dumped on the river bed between the harbour and the Loom Pit which is usually covered at spring tides. If the spring tides and tidal surges can no longer spread into that space the water will flood somewhere else. That is one of the reasons the river is becoming shallower outside of the commercial channel.

Yes it is Cantata. If the spring tides and tidal surges cannot spread across the river bed as happens now, that water will just breach the bank elsewhere. A massive amount of water goes there during a high tide.

only if the sea wall is raised, moving spoil from SYH to the shallows of the river will make no difference

It is a real nighmare as the silt mostly comes down the river but imagine the cost of returning it to the land beside the upriver source. It would be ideal to do it but who bares the cost? The last two dredger masters from the Orwell used to take the spoil out to sea but now it is often dumped in the river but outside the channel.

There has been massive changes there because of the dredging out along the main channel has changed the beach and moved other shingle around and I know little about that except what I hear. However the Orwell is in serious danger again of silting IMHO because commercial interests are only interested in the commercial channel.

The spoil from dredging for Woolverstone Marina all went back around Colimore. That was not maintenance dredging either but capital dredging. The problem is this is all being organised from Newcastle by MMO now not that they are any different from EA.

The tree huggers wont allow the spoil to be removed from the river. That is the problem

And commercial interests. I always thought on the Orwell silt came down the river though? Where Fox's is now was once the river bed and of course the West Bank was also river bed as was a good part of Cliff Quay. Once the flow is squeezed too much it has to find somewhere else to go and that means flooding of course as we have just seen. EA have just spent a fortune on the bank at Wherstead and it was over topped within weeks of the work being completed. That then hindered the escape of the water trapped behind the bank.

I used to work on a dredger that picked up aggregate and took it to Flushing for processing. That was a 10 day turn around journey just going there and back for 10 days but that doesn't happen anymore.

Thus making the water outside the channel much shallower. You cannot sail a metre keel between the East Fen buoy and the Quay opposite Fox's now at low water. Even a dinghy will touch there. The state of the Orwell is becoming alarming.

It is no longer going to be put into the shallows. It is being pumped onto the flood plain beside the harbour so eventually it will no longer be a flood plain and flood tides and surges will have to go elsewhere. The river wall here is artificial and is covered by most tides anyhow.
