  While I do appreciate that a great deal of dredging has taken place recently, and thumbs up to the BA for that.

Dredging work started on Oulton Broad, and then sort of stopped half way through.

Will the dredging carry on? I notice that ABP are doing a lot in Lake Lothing any chance they can help us out?

  Don't think BA have done any dredging on the Waveney between Geldeston and Beccles, but they have been busy cutting fallen and overhanging trees in the navigation. Only shame is one or two large branches are now floating in the river half submerged waiting to catch out the unwary !

  Dredging has been undertaken on Oulton Broad every few years over the last few decades with an average of about 20,000m3 per five years. It is a huge location and we have to balance it with other dredging requirements throughout the Broads given our budget and the availability of sediment reuse sites. To undertake a large scale campaign throughout Oulton Broad would require the removal of over 80,000m3 of sediment which would require more land and more budget than we have for the whole of the Broads. Therefore to make sure the whole network gets the required dredging we prioritise areas and move about accordingly, returning to Oulton more frequently than other broads so this is planned activity rather than stopping part way through.

  80 thousand cubic meters of broads muck is one hell of a lot of stuff to get rid of.

Could not the development of the old Pegasus yard have been used as dumping ground as I believe the planning authority required that they increase their level above mean water?

  Dredged materials are classified as a ‘Waste’ under the Environment Agencies Waste Classification criteria and as such they cannot just be placed anywhere.

The Broads Authority current policy is to look to reuse the sediments in a sustainable manner and over the last few years we have developed innovative techniques  to use the dredged materials for habitat creation (Duck Broad & Salhouse Broad), spreading onto agricultural land for benefits to farming or for crest raising current flood defences.

The land at Pegasus was not an option for sediment disposal.
