Down below the surface of the dyke the weed is now definitely on the march, even since this photograph was taken it will have inexorably advanced still further. Proper underwater forests with the weed caching the surface forming a canopy that provides shelter for the underwater wildlife. Goodness knows what is lurking down in those underwater clearings and weedy canyons.
We've seen a few eels in the long dyke and there are small perch, roach, rudd and bream plus hundreds, probably thousands, of sticklebacks. No doubt there are plenty of damsel fly and dragon fly nymphs too and there must be masses of bloodworm down in the depths; we've also seen some beetles in there that were well over an inch long too.
A spot of wild swimming anyone?
