Update regarding flooding within the Borough.

Published: 05 February 2021

Please find below an update regarding flooding within the borough.

We met with stakeholders yesterday through the Tactical Coordinating Group which is in place to formally coordinate any multi-agency response needed. The Met Office has confirmed that they are not forecasting a lot of rain in the next few days. However, there is a yellow warning for snow.

Please find the link to the Environment Agency for their updated flood alerts. This link is for Berkshire as a whole but you can see the alerts within the borough - https://flood-warning-information.service.gov.uk/warnings?location=berkshire. River levels are likely to stay high for now.

There are three main areas of focus at the moment:


The B4447 The Pound between School Lane and Terry’s Lane remains closed.

The A4094 from Bourne End into Ferry Lane has now been closed by our colleagues in Bucks Council. Signs will be put in place on the A4 for motorists.

The Arriva bus service is now on diversion as The Pound and Cookham Bridge are closed. GWR will accept bus tickets on their services between Cookham and Maidenhead until 6pm on Friday 5 February. We’re in touch with GWR and will advise on a further extension if necessary.

The Causeway Plan is ready to be activated if needed and we will continue to monitor the situation as the A4094 Sutton Road into Cookham remains open.

A flood warning is still in place so we will remain vigilant to the potential risk to properties but water levels are stabilising.

Crews continue to monitor the situation and will be on standby over the weekend, and we will update you if anything changes.

Old Windsor

We are working with Surrey County Council and they have closed the A308 between the roundabout at A328 to just after the Runnymede Pleasure Ground.

The Environment Agency has reviewed the situation and at this stage flood defences are not being deployed because of the Met Office improving forecast but this will be reviewed.


Attention is being paid to flooded gardens from the Thames on riverside properties and in Wraysbury from Old Windsor weir to Magna Carta Island.

Flooded roads are being monitored including The Island and King John Drive.

Horton and Wraysbury

The council is also working with the EA in monitoring levels on Colne Brook.

If you have a concern about flooding in your community please encourage residents to report it through the website – https://www.rbwm.gov.uk/home/transport-and-streets/roads-and-pavements/report-flooding-or-drainage-problem

Please remember we are still in a national lockdown and we urge people to remain at home, as long as it is safe to do so. We are asking residents to stay away from flooded areas and rivers as they can be highly dangerous. There is also the additional risk of COVID-19 and residents are reminded to keep their distance from other people.
