    Kyd Brook S.W.O upstream by Kirsty Blackman

    There is a tree that has fallen into Kyd brook a little further downstream from this point, this has caused a dam as now vegetation hs become trapped and the water levels are now a lot higher than normal, please see photos.

    There is a tree that has fallen into the brook a little further downstream from this point, now vegetation has also become trapped and it's formed a dam which means that the water is artificially high now, please see photos.
