“Rivers are full after the wettest April to June on record, followed by more rain in July, September and October. The earth is saturated and in many areas there is no more space left in aquifers to store water that seeps through from the surface. The Environment agency warns that people should be ready for floods even with relatively small amounts of rain.”
So begins a BBC news item today. “Aha,” I think to myself. “If I take a look at the CaRT Reservoir Watch figures then, it’ll presumably tell me the reservoirs are all full”
Well, not entirely it seems. I was a bit surprised and puzzled by what I saw. Here is my updated graph, now showing percentage full of selected canal reservoirs from January 2011 to October 2012.
Compare this October with last October and you’ll see a huge difference. As usual, the K&A figures are all over the place. We still don’t know why, but we’re used to it. Sure enough a number of the others are full, but what’s going on on the GU South? I wouldn’t have thought that the boat traffic there was any more than, say, the Oxford, and a number of the GU flights have back pumping too. I’d love to know the answer.
As to others, the BCN, Chesterfield, Huddersfield Narrow and the Lancaster are all at or below 70%. I thought they were up in the rainy bit. Anyway, the people in the know seem comfortable with the figures. The comment on the CaRT site includes the following:
The rainfall has ensured that the reservoir holdings for the vast majority of our network are at a very good status, compared to the Long Term Averages for this time of year when our reservoirs would typically to be at their lowest holdings, or just starting to show autumn refill. To illustrate this, the Oxford Canal reservoir group is now at 95% full, compared with just 20% full this time last year and the Leeds & Liverpool Canal group is now at 91% full, compared with just 25% full this time in 2003. The overall water resource position and hence the outlook is very good, and there is a high degree of confidence that the 2013 main boating season will be able to start with good reservoir stocks, a very marked contrast to how the situation was looking a year ago.
As for those poor boaters on rivers, they’ve had a tough year haven’t they. I’ve lost count of the number of blog reports of folk stranded in dangerous conditions on the Thames and the Nene this year. Now I see the Yarwoods and the Matilda Roses look set to spend the winter stranded on the fens. I can think of worse places to be stranded but I hope they have plenty of woolly jumpers. It gets cold out there.
