Flood alert expected for Northumberland river after erosion of raised bank holding back water
and live on Freeview channel 276
The River Coquet overtopped following heavy rain last week and merged with the Caistron Lakes, near Rothbury.
The river has split in two, with around half now flowing into the lakes area, which is currently holding anywhere between 100,000 and 500,000 cubic metres of water.

This bank is now at risk of failure.
With local catchments saturated, combined with forecast rainfall and snowmelt, the river level is expected to hit the trigger level to issue a flood alert tonight. As a precaution, the flood gates at Rothbury will be closed this afternoon.
The Environment Agency is now working with partners including Northumberland County Council, Northumberland Fire and Rescue Service and Northumbria Police to reduce the risk to the local area.
Should the bank fail, it will release water from the lakes area downstream.

Hide AdWhile the extent of the floodplain means this additional water won’t create a sudden impact, it does have the potential to raise river levels more quickly than normal and flood agricultural and low lying land and some recreational areas including low lying public rights of way, public roads and the Cow Haugh car park at Rothbury riverside.
Northumberland County Council is working to address any public safety concerns through the temporary closure of footpaths, car parks, and play areas in low lying areas and the flood plain, when river levels dictate.
Partners are working together with the landowner to find a solution to the lake bank erosion.
A meeting in 2019 involving agencies including the Environment Agency, Northumberland Rivers Trust, Natural England, and landowner, fisheries and council representatives, discussed the potential issues with the River Coquet and the likely future overtopping or breach.

Hide AdAndrew Turner, area duty manager at the Environment Agency in the North East, said: “We’ve been closely monitoring the River Coquet over recent years and since our meeting in 2019 we have developed a robust incident response plan to minimise the impact on the community and environment.
“The overtopping into Caistron Lakes – a set of man-made ponds – took place last weekend (February 6) during heavy rain and high river levels. We’re assessing the current situation and looking at options to ensure a gradual release of the stored water.
“Our priority is the safety of the public and we will keep people informed of our activities and the latest information.”
Caistron Lakes were created many years ago when the River Coquet overtopped into a sand and gravel extraction site. The new breach will ultimately create a new channel for the River Coquet.

Hide AdAndrew added: “Longer term, we will be working with Natural England to monitor the impact this has on the main River Coquet and the environment. The Coquet is a naturally wandering river and erosion, switching channels or the formation of new channels is an entirely normal occurrence.”
