That is quite fascinating, Jon, especially those in the NW of England which
are the lowest - only 44%, yet those in the driest places of late (S and E)
are above 50% and E Anglia is at 73%.

So the NW reservoirs are the lowest in the country?

I find that difficult to believe.

I find that difficult to believe.

Why, is there a better authority than the EA?

Perhaps the wetter areas are less concerned with plugging leaks, so they
suffer more in dry spells?

I'm just surpised, that's all.
In percentage terms the rainfall up here may have been similar to
that down south, but in absolute terms it's been much higher.

I suspect it may have been increased useage further south, perhaps more
gardens watered, more cars washed etc, rather than just the effect of less
rain in Cumbria.
Passed Thirlmere today and it did look well down but not exceptionally so.

The expectation of rainfall over northern England
(especially in the reservoir catchments) is higher
than southern England. Percentages are probably
not the best way to compare capacity etc. The
figures were much worse in autumn '94 or '95, i
forget, (23% IIRC) and we survived the very dry
winter, spring and summer that followed. Only
just, maybe, but infrastructure/capacity has
improved since.

But where do the various water companies actually obtain their
supplies from. I suspect that the SE uses far more bore hole water
than reservoirs. After all it's a bit difficult to build a reservoir
when you haven't any hills to use as the sides...

I was quite surprised by a statement from Severn Trent last week.
Words to the effect that "no matter the weather they can 100%
guarantee the water supply for the next 5 years". Yorkshire Water
weren't overly bothered about their reservoirs being at or just over
50% full, 2" of rain will fill them all back up again.

Something has been bothering me for a while -

I regularly run through what is know as the 'Water Catchment Area' on the
north edge of the North Downs. There is about 4 reservoirs in a particular
valley with lots of man made half-pipes dug into the hill sides that run
into them. It amazes me that during the summer, when hardly any rain fell
at all here (Aug 17mm, Sept 4mm) that water was running, not just trickling,
down nearly every half-pipe all the time. Even when it didn't rain for
something like 3 weeks at the peak of the summer heat, there was always
water rushing down into the reservoirs. I'm not aware of any springs in the
area, so where does all the water come from?
