For

Storm

South
Quay, the bank of gravel to be uncovered so that vessels can dry out

The
northern walkway be raised so that it does not flood(plan was

time and ignored the warning)
Works
to be carried out subject to
EU
Waters Directive
EU
Eels Directive
EU
Legislation on migratory fish and access to spawning and nursery
grounds.
We
have been told that the ponds are managed in a healthy state,that has
never happened since the sixties
There
is insufficient fresh water inflow (Welsh Water Survey)to prevent
eutrophication.
Since
the gate has been removed both ponds have recovered
,Most
of the swans have left leaving a healthy breeding group, bass mullet
eels sea trout have returned as have waders and wildfowl and the
alien rapidly growing vegetation planted at great public expense has
been removed to be replaced by native tidal vegetation which does not
require constant cutting.
A sound decision for aesthetics conservation and financial grounds
