Secondly,how long does it take for the 6" of water covering most of
England at the moment to seep down into the aquafers ?,all the ponds
in this area are full to the brim,and with very little evaporation
going on now because of the perishingly low temps,it must be going
somewhere,oh yes ,the River Lee is two miles away,and the drains are
also overflowing. All the trees not standing in water ,are in danger
of hyponatremia (look it up) and all the messages continuing to flow
from the 'experts' urging us not to be complacent,because next winter
maybe dry quite frankly ****es me off !

Now that feels better.

I agree to some extent because water abstraction from rivers will soon
be able to top up resevoirs where this is their main source, But
underground aquifers work on much larger timescales as you know, so
there has to be an element of long term prudence.
My rainfall so far this year is only 200mm with half of that coming last
month. That would equate to a fairly low less than 500mm for the year.

Plus it is primarily winter rainfall that recharges the aquifers.

It takes really wet months for anything significant to recharge aquifers
at this time of year.
