Black silt in drainage ditch
 

Our allotment has no piped water, but plenty of water running in ditches on
the sloping site.
These never run dry as we are on a natural wetland with a clay subsoil.
However the sunken baths used to store water regularly silt up with a fine
almost black substance.
This is removed from the baths and piles at the sides.
After drying out it forms a fine (almost powder) soil.

Does anyone know what it might be.
Thanks

Does your wetland include peat?

Out here on the edge of the fens, that small particulate stuff dries and
gets deposited all over the windowsills (and washing) every time we get a
Fen Blow.

I'm on the northern half of the Isle of Wight on clay , so there are no deep
peat deposits that we normally associate with peat.
However I guess peat is forming all the time.
