    Kyd Brook S.W.O upstream by Kirsty Blackman

    Even though this water way is polluted further upstream in deeper pockets there are baby stickleback, I'm presuming and a pair of Mallard Ducks. For the past few years a pair of Mallard Ducks have been located here but there are never any sightings of baby Ducks so I again presume that they just visit for the fish.
