This category contains flood alert information, in particular the water levels in the Tilshead Borehole. Graphs will be published weekly from 1st December through until the end of March.

Tilshead Borehole Level – 1st December 2016

The first reading for this years Flood Risk Season shows a level of 79.7 metres, roughly average for this time of year.  The level has been falling slowly but steadily since the heavy rains a week ago.  There seems to be little rain in the forecast (see below), so little prospect of sudden changes in the aquifer.

The weather forecast for the next period is as follows:

UK Outlook for Tuesday 6 Dec 2016 to Thursday 15 Dec 2016:

Tuesday is likely to see more dry and settled weather for most of the country, with sunny spells. Where the cloud breaks overnight, this is likely to bring local frost and fog. However, the far west of the country is likely to become breezy on Tuesday, with some patchy rain later. From Wednesday, this rather wetter and windier weather will gradually spread further south-east. As it does so, the wind and rain will gradually ease so the south-east may well stay dry. It will become milder across the country with less frost than recently. Into next week, this milder, wetter and windier theme is likely to continue but in general, winds will be stronger and rain will be heavier in the north-west, whereas the south-east will stay drier and quieter.

Tilshead Borehole Water Levels

For the last few years, Andy Shuttleworth has been monitoring the water levels in the Tilshead borehole during the winter.  This, together with rainfall data provided by Janet Abbott’s wonderful website at: http://www.winterbournestokeweather.co.uk/  gives us a little bit of warning as to when some of the lower lying properties in the village may experience flooding from the rising water table.

We will be publishing weekly updates to the information which will look something like this:

The straight blue line at the top of the graph show the level when water spills out of the borehole in Tilshead.  When this happens, we will have flooding in some properties in the village, as happened over Christmas/New Year 2013-2014 – shown by the Yellow dotted line.  The black dotted line shows the average depth of water in the borehole over the last 4 years.   This years data will be shown by the red dotted line and will go live on December 1st.
