I ask becourse my childhood luggage (my father was a gardener & fliefisher)
says that the long swaying algae (local name:SheepTails) signifies a lower
waterquality - this may not exactly be what's at the pictures, in any case
it's at odds with the fact that it's swaying in non-poluted water welling
out from cracks in the chalk (catchment area largly woodland)
