52/2012 Week 3

Third image for the 52/2012 Challenge taken at Lyn Brenig, North Wales

Llyn Brenig is a reservoir located in North Wales, in the heart of the Denbigh Moors, on the border between the counties of Conwy and Denbighshire. It is used to manage the flow in the River Dee as part of the River Dee regulation system which is designed to protect the water supply for North West England and North East Wales, particularly Liverpool and its surrounding area.

Construction began in 1973 and was completed in 1976. It has a capacity of 60 million m³ and was first filled in 1979. With a surface area of around 920 acres (3.7 km2), it is the fourth largest lake in Wales, behind Llyn Tegid (Bala Lake), Llyn Trawsfynydd and Lake Vyrnwy. The lake has a perimeter of some 14 miles (23 km).

The catchment of the reservoir is very significantly over-reservoired. This means that the reservoir cannot fill from its own catchment within one annual hydrological cycle. When the reservoir level is drawn down, it can take several years for it to completely re-fill again. Llyn Brenig is therefore only used during drought conditions when the capacity of Llyn Celyn and Llyn Tegid are no longer predicted to be capable of maintaining the flow in the River Dee.

During construction of the lake, a number of Bronze Age artifacts were found, as was a camp used by Mesolithic hunter/gatherers. This has been dated by radiocarbon analysis of the charcoal from their fires to around 5700 BC. There are a number of archaeological trails around Llyn Brenig; the relics visible include a ring cairn (a Bronze Age burial mound), and several barrows.

A visitor centre to the south of the lake displays a lot of archaeological information about the area.

A number of watersports take place on the lake, including sailing, fishing, and canoeing. The only power craft allowed on the lake are those used by fishermen, and sailing club safety craft. In 1990 it was selected as the only Welsh reservoir used for the World Fly Fishing Championships.

Access from the West is via the A5 to Cerrig-y-drudion and then the B4501, the Lake is well signposted. From the East, after leaving Denbigh, follow the A543 to Pentrefoelas for about six miles and then turn left onto the B4501 for about three miles – look for the Llyn Brenig Visitor Centre signs.

On the day I visited Lyn Brenig we’d had a sharp frost over-night and there was an extremely cold wind blowing. It does not make for comfortable handling of camera equipment and tripod.

  1. Beautiful capture. If it was mine, I would have cropped it a little on the left. For some reason the open space on the left of the trees doesnt feel right. Its hard to explain. The whole picture has light areas, except the left part.

    But thats just my two cents 🙂
