I had a similar view in 1968 July, the preliminary rain to the 1968 Floods in Somerset had already sent the Elan Dams over, but I was fortunate to be in bright sunlight so this was blue rather than white water as in the photograph by Claire in the rain. Below the wall as shown by Toby there is the most excellent set of scour holes in the Greywacke rock. Students in Landscape Architecture have seen these many times, but I no longer have the photographs. Possibly the best dam view for overspill. These days everything is safely spillway and chute controlled, good but boring. The stone work is brilliant on these dams as in [[ SO2330]] Fawr, Martin Wilson. If Landscape and Architecture can help to keep these features in the country through the Planning and Resource controls and Agricultural systems and they become more accessible, safely, with better designed timber walkways and enhancing structures rather than old industrial junk then they make superb teaching and recreation facility, as well as keeping them effective for ongoing research. Obviously biosystems relate to this type of scenery, but apart from kingfisher and some insects and as watering points for birds in general, only some of this is known by myself.
