Alan, I have a vague memory, presumably from 1997, of the Ver
drying up all the way down to St Albans, ruining the watercress
beds. Is that right, or is it an older memory intruding?


Not too sure about '97 but certainly '95 and '90 however water

abstraction
at Friars Wash was much higher then. Incidently I seem to remember

that
the
lower levels of abstraction were due to the diversion of water from

the
Lea
catchment around Luton. I could be wrong on this but if it were the

case
it
would smack of robbing Peter to pay Paul given the drying out of the

Lea.

Ah, now things are beginning to fall into place. That would explain a

lot.
It can be argued that it's no great loss as far as Luton is concerned.

Such
a
large part of the town was built in the catchment in the last 100

years or
so,
with so many houses in the flood-plain, but during the period when
artesian abstraction was at its highest, so I guess there were few

concerns
about flooding. After 2000-01 it was clear that hundreds of houses,
dozens of businesses, parts of the A6 and the inner ring road, were

all at
risk from flooding resulting from a combination of a rising water

table and
an extremely 'flashy' catchment. The one big loser in all this is the

big
lake in the rather attractive Wardown Park which has comprised

extensive
mudflats since August.

I think that the water abstraction at Friars Wash was reduced by taking
more water to Luton from Grafham Water so it should not have had any
local effect in the Luton area.
