Environment Agency River Levels

(Previously when Cocker Beck *** WARNING *** is given there is just one hour until it overflows). The Alerts are useful to know when the situation is getting worse but it is the WARNINGS when you need to take immediate action.

River level Cocker Beck at Lowdham Grange.

River levels on the Dover Beck

When the Cocker Beck gauge goes above 0.6m start putting on your first level of flood defences. While it has never flooded when the Beck just reaches 0.6m, the beck could go higher (due to past or future rainfall in the catchment area) so use this as a trigger to do something to protect your property.

Weather Forecasts

Weather Forecast

Accuweather Forecast


Weather Forecasts do differ so use the one you ‘believe’ in. The Accuweather forecast  is usually very accurate within their 120 minute window (handy for knowing when the rain will stop – but remember the rain that falls upstream takes a while to reach Lowdham so the beck can rise for at least an hour after rain stops).

The Met Office have explained that certain clouds (Cumulonimbus) are worse than others at causing large downfalls. Here is a picture of what these look like Cumulonimbus Clouds and the Wiki definition is https://en.wikipedia.org/wiki/Cumulonimbus_cloud.Clouds do not have to be black to contain large amounts of rainfall. It depends on the conditions and process of cloud formation for example how the water particles coalesce, the speed with which it happens, whether there are ice particles and all this in turn is all directly connected to what is happening in the upper atmosphere. Some clouds can look really threatening but produce nothing at all. Cumulonimbus clouds more often than not will produce precipitation but not necessarily during their decaying phase.

Ground Saturation

The condition of the ground determines how much rainwater seeps into the ground or runs off. The term the EA use is Soil Moisture Deficiency. The EA do publish weekly rainfall summaries which are useful in determining  how much rain has fallen.
