DisgrifiadA pond on the northeast side of the Grwyne Fawr valley, near the reservoir. It was created by a 30m dam on the south side running east-west across the slope in a slight arc. The earth bank of the dam had upright metal sheeting at its core. The dam had been breached when recorded in September 2007 and the pond only held a small amount of water.
