Tilshead Borehole Levels: 3rd March 2017

Only one month remaining of this year’s monitoring period and water levels are more than 5m below the 4 year average.  During February, we had 45mm of rain which is about the same levels we had back in the winter of 2014-2015.   That’s nowhere near the 136mm we had back in 2013-2014. Despite the rain last week, the water levels in the borehole tailed off and have now flattened out completely.  If you look at the other traces from earlier years you will see that March is when we would expect to see the levels begin to fall.  That’s simply because two things are happening in parallel.   Whilst there may continue to be lots of rain (we had 81mm in March last year) , the grass has started to grow, trees and shrubs are coming in to bud and they are using large quantities of water to do so.

It’s raining now and we have a lot more rain forecast for the day and later on in the weekend.  Showers and longer periods of rain are predicted for the rest of the month. It’s entirely possible that we could exceed the total rainfall for March 2015 (9mm) by the end of today; as I write, it is 8:30am and we have already had 3mm of rain.   This week could prove the most interesting of the winter for water levels in the borehole.




Tilshead Borehole Levels: 24th February 2017

The rise in the water level at the Tilshead borehole has continued during the week, despite there being only 4.3mm of rain during the period.  The rate of increase has tailed off though.

We have some wet and windy weather forecast for the weekend and early next week.  In the longer term, the forecast is very vague – it could be wet, ot might be cold.  We will have to wait and see!

Tilshead Borehole Levels: 17th February 2017

Despite only having 3.3mm of rain over the last 7 days, the water levels in the Tilshead borehole have continued their inexorable rise, though the rate of increase has slowed considerably.  It just goes to show how sensitive the aquifer is to even small amounts of rain once the water level has exceeded the 82 metre mark.  That said, we are still a long way below the levels seen over the last 3 years.

There may be a little drizzle today and aome early next week, but no major rainfall over the next week or so.  The end of February into early March is looking to be increasingly unsettled, with bands of rain sweeping across to the east.  There may even be a bit of snow around the corner!

Tilshead Borehole Levels: 10th February 2017

The level of water in the Tilshead borehole has been on a bit of knife edge for a week or two now, in the sense that over the last few years water doesn’t start to flow in the Till under the bridge in Church Street until the water level in the borehole is somewhere between 81 and 82 metres.  We moved into that region last Friday and sure enough, the rain we have had over the last week has pushed us over that first point.  So the chart for this year shows a sharp upturn, but there is no need to panic!

The weather forecast suggests we might have a little light sleet or even snow over the weekend, with some light rain in the first part of next week.  A little more rain may be on the way fro the following weeks, but there are no deluges in the forecast at the moment.

Tilshead Borehole Levels: 3rd February 2017

Well, it seems as if the winter rain has finally arrived, although the totals for January, at 60mm, were a little lower than the 189mm we had back in 2013-14 or even the 94mm we had last year.  The levels in the borehole are just starting to head upwards, but only very slightly.

The weather forecast for the weekend is for a little more rain today, with a fine day on Saturday and perhaps a drop or two more rain on Sunday and Monday.  We seem likely to have some rain up until the middle of the month when a drier and colder spell might kick in.
