09.08am Saturday 8th December Flood Alert no longer in force.

The EA have cancelled their Flood Alert and sent the following explanation:

"We issued the alert on Friday evening as you are aware, and fortunately no flooding was experienced.  This is because we were able to make weir movements to manage the level of the Thames. However there was some miscommunication between our incident staff about these weir movements, which meant that we issued the alert when we didn’t need to do so. We will make sure this issue is covered at our next training session with our incident staff. Thank you for sharing the alert and asking for feedback from the community. "


 7.50pm Friday 7th December The Environment Agency has issued a Flood Alert for the River Thames from Hurley to Cookham.

The River Thames upstream at Cookham Lock is at 14cm.     This is much below the level at which serious community problems like the closure of the Moor Road occur (100cm).  Cookham Parish Council Flood Committee is watching the situation closely.  We are surprised to see that we are the only area in Berkshire on Flood Alert. Normally if there is a problem on the Thames, the Cut, Datchet and other areas are on flood alert too. Please report any flooding problems in Cookham to cookhamflood@gmail.com or post below. The next text is the EAs, and the posts below give local forecasts and information pulled together for Cookham by the Parish Council Flood Committee.

A Flood Alert has been issued by the Environment Agency.

Flood Alerts and Warnings

Flood Alerts and Flood Warnings for four areas relevant to Cookham are issued by the Environment Agency and published on the gov.uk Flood Information Service , as well as via the telephone, text and email flood warning service.

When things first start to look dicey, the Environment Agency will declare a Flood Alert for the 'River Thames from Hurley to Cookham'. This area includes Cookham village, East Cookham Rise, the parts of Cookham Dean down by the river, Spade Oak Reach and Cock Marsh. 'Flood Alert' is the lowest level of warning and indicates "Flooding is possible. Be prepared."

If things get worse, the EA will declare Flood Warnings for smaller parts of the Hurley to Cookham stretch of the Thames. Most of Cookham is covered by an area named 'Cookham village and east Cookham Rise', which includes Marsh Meadow, Cookham Moor and Widbrook Common.

For people concerned about Spade Oak Reach and Cock Marsh, the appropriate EA Flood Warning area is the River Thames at 'Bourne End'.

For the parts of Cookham Dean down by the river, the Flood Warning information is given in the area the EA call 'River Thames at Marlow and Bisham'.

The EA map of our Flood Warning areas shows which parts of Cookham fall into each area (pdf 2.9MB), with kind permission of EA Partnership & Strategic Overview team, Berks and Bucks, 14 September 2015).

Weather forecast relevant to flooding of the Thames

Why show a weather forecast for Oxford instead of Cookham? Flooding in Cookham is determined by the rainfall in the upstream catchment of the River Thames.  Oxford is roughly in the middle of the upstream catchment and so the rainfall forecast there is a better indicator of future flooding than a more local site. It takes a couple of days for rain running into the Thames at Oxford to flow down the river to Cookham.
