Street View of Llyn Brianne | Map of Llyn Brianne location

The Llyn Brianne reservoir was built in 1972 by damming a section of the river Towy to supplement flows in the river during low flows, and as compensation for extracting water supplies some 40 miles downstream at Nantgaredig. The dam is supposedly the UK's biggest standing at a height of some 300ft. Because of the importance of the River Tywy salmon and trout fisheries special measures were incorporated into the construction of the reservoir including a smolt trap and a restocking programme. The Upper Towy Valley and Llyn Brianne is still one of the most beautiful areas of Wales and it is a haven for bird watchers, anglers, mountain bikers and walkers. Mountain Bikers are particularly well catered for with nearby Llanwrtyd Wells being something of a centre for the sport with several trails commencing in the town. These include the Mynydd Trawsnant Trail, the Irfon Forest Trail and the Esgair Dafydd Trail.....
