Dredging has started on Hickling Broad as cold temperatures allow work to begin.
The priority dredging involves sediment being removed from the top end of the Broad near the sailing club and Parish Staithe.
This will be transported to Duck Island where it is being pumped into the lagoon created by the Authority in 2013/14.
The project aims to remove 3,000 cubic metres of sediment within 10 weeks and top up the lagoon area. The extra material being placed into the lagoons will further help the colonisation of reed and reed mace (typher).
The dredging is being carried out in accordance to the strict specification set by Natural England to ensure the vitally important habit and ecology of Hickling is protected.
