Disused weir on the Afon Cynffig, Pyle (2)

Image: © eswales Taken: 6 Oct 2012

A structure identified as a disused weir on large scale Ordnance Survey mapping, but as a dam in some other sources, and which once played a role in the diversion of river water to Llanmihangel Mill is seen here following substantial rainfall. Water flowing downstream may be seen to pass through here at three separate points. Much passes along a channel (at far left of picture) just beyond the western end of the main wall of the structure, although a considerable amount passes through two openings in the stonework – one in a side wall of the channel, the other in the main wall. By contrast in Image, taken a year earlier, it may be seen that water only passes along the channel, a consequence perhaps of the earlier photo having been taken at a time when there had been less recent rainfall and the river level was therefore lower.
