This £27m project involves raising the mid-level barrier bank from Earith to the Welmore Lake Sluice just past Welney, and will take four summers to complete. The works will see the bank raised from between 600mm and 800mm - depending on the section - along its 30km length.
Jackson has now completed the third section of works which has seen over 380,000 tonnes of material used. The third season of works included:
Welches Dam Pumping Station
The installation of a new bridge with increased weight limit and the construction of 100 metre reinforced concrete flood wall connecting the newly raised embankment either side of the pumping station.
Sutton Gault Retaining Wall
The team have extended the retaining wall by 16 metres at Sutton Gault to suit the new profile of the embankment.
Two bird hides have been construction at Welches Dam and Rickwood in time for bird watches to view the thousands of Wigeon and Whooper Swans which will be returning from Iceland for the winter months. These bird hides were EA and RSPB designed agreed and constructed using steel frames and timber and positioned on concrete pads. The team will be constructing an additional three bird hides at Stock Dale, Cadbury and Cottier over the next two seasons.
Mid-Level Barrier Bank
The team have now tied in 300 metres of small localised bank raising works into the A1123 which runs through Eairth village.
During the works this season, Jackson have conducted school visits engaging with year three and four pupils from Sutton C of E V C Primary to learn about the history of Ouse Washes and how it operates today. The team also raised £90 through their Macmillan Coffee Morning in October.
Jackson’s Project Manager, Brendan Saunders said: “We have had a really productive and positive third season at Ouse Washes in 2019. We have made good progress in the two sections of bank raising this season, in spite of having to deal with huge amounts of rainfall and flooding on site over September and October.”
“It’s also really pleasing to have completed the structures work at Sutton Gault and Welches Dam, with only the Welney barrier structure left to complete. We are crossing our fingers for better weather for our summer returns in 2020 and 2021!”
