Completed Maintenance Works

Well Creek – (Phase V Marmont Priory Corner to Thurlands Drove Junction, Upwell; Hall Bridge Road Junction to New Bridge, Upwell & Isle Bridge Outwell to Outwell Boat Basin)

The Commissioners have undertaken the fifth phase of channel maintenance dredging works to remove siltation and sediment from Well Creek. This took place during January/February 2019.

The resultant dredgings were transported away from site to Salter’s Lode. They are being stored and left to dry sufficiently to then be re-handled and re-used elsewhere in the Commissioners’ river system as bank raising material.

Below is a short video demonstrating the process.

Old River Nene(Bevills Leam Junction – Speed the Plough Junction)

Maintenance dredging works commenced during late December 2017 to remove siltation from the bed of the Old River Nene from Bevills Leam Junction to Speed the Plough Junction. It was necessary to work from both sides of the raised embankments to afford the contractors 18-metre-long reach machine the ability to reach the centre of the channel. The silt material has been placed along the crest of the raised embankments, where it will be left to dry during the spring months. The material will raise and strengthen the existing raised embankment. Final levelling and grass seeding will be undertaken during the summer.

Great Raveley Drain(Speed the Plough Junction – MLC Control Sluice)

Maintenance dredging works were undertaken in January and February 2019 to remove accumulations of silt from the Great Raveley Drain. It was necessary for our Contractor’s 18 metre long reach machine to work from both sides of the watercourse, where bankside access was afforded in order to gain the necessary ‘reach’ to dredge the centre of the channel. Dredging’s have been placed along the bank top and allowed to dry out. Once dried, the material will be shaped and levelled into the existing raised embankment. The dredging operation not only removes the silt from the water channel to assist with water conveyance during high rainfall events, it also helps to provide locally sourced material with which to strengthen and raise the bank crest, helping us to protect land and property from flooding in the future.
