Ffynnon Llugwy is a lake in the Carneddau range of mountains in Snowdonia, North Wales.

It lies at a height of about 1,786 feet (544 m) and covers an area of some 40 acres (16.19 ha). It has a maximum depth of 146 ft (45 m). [1]

Since the early twentieth century water has been taken from its outflow, Afon Llugwy to feed Llyn Cowlyd via a series of leats.

Since the mid 1970s the lake has additionally acted as a reservoir for Bangor and eastern Anglesey, which necessitated the laying of an 11-mile pipeline to the water treatment works at Mynydd Llandygái. [2]

It is the source of the River Llugwy (Welsh : Afon Llugwy) which flows via Capel Curig and Betws-y-coed before becoming a tributary of the River Conwy.

Llyn Cowlyd is the deepest lake in northern Wales. It lies in the Snowdonia National Park at the upper end of Cwm Cowlyd on the south-eastern edge of the Carneddau range of mountains, at a height of 330 metres (1,083 ft) above sea level. The lake is long and narrow, measuring nearly 3 kilometres (2 mi) long and about 500 m wide, and covers an area of 1.1 square kilometres. It has a mean depth of 33 metres (108 ft) and at its deepest has given soundings of 70 metres (230 ft), this being some 14 m (46 ft) greater than its natural depth, the water surface having been raised twice by the building of dams.

<span class="mw-page-title-main">Llyn Crafnant</span> Natural lake in North Wales

Llyn Crafnant is a lake that lies in a valley in Wales where the northern edge of the Gwydir Forest meets the lower slopes of the Carneddau mountains and, more specifically, the ridge of Cefn Cyfarwydd. The head of the valley offers a profile of crags which are silhouetted at sunset. The Forest Park guide (2002) states that "the is one of the most breathtaking views in all Snowdonia". The summits include Crimpiau 475 metres, and Craig Wen 548 metres which provide views to Moel Siabod and the Ogwen Valley, and Snowdon. Further up is Creigiau Gleision. At 63 acres (250,000 m2) it is the best part of a mile long, although it was clearly once much longer - its southern end shows the evidence of centuries of silting. Jehu's survey (see references) recorded a maximum depth of 71 ft (22 m).

<span class="mw-page-title-main">Llyn Geirionydd</span> Lake in Snowdonia, Wales

Llyn Geirionydd lies in a valley in North Wales where the northern edge of the Gwydyr Forest meets the lower slopes of the Carneddau mountains. The lake is almost a mile long and covers an area of 45 acres (180,000 m2), but is never any deeper than 50 ft (15 m) according to Jehu's survey. The lake can be reached by car from Trefriw or Llanrwst in the Conwy valley, the lane passing through the hamlet of Llanrhychwyn, or from the road through the Gwydir Forest. Access is not particularly easy by either route, but this has not stopped the lake being the only one designated in Snowdonia to permit power boats and water skiing. Many visitors also walk to the lake from the village of Trefriw or from the neighbouring lake of Llyn Crafnant, which runs parallel to it, but a mile distant, the two being separated by Mynydd Deulyn, “mountain of the two lakes”.

Llugwy may refer to a number of places and archaeological sites in Wales:

<span class="mw-page-title-main">Llyn Ogwen</span> Lake in northwestern Wales

Llyn Ogwen is a ribbon lake in north-west Wales. It lies alongside the A5 road between two mountain ranges of Snowdonia, the Carneddau and the Glyderau. Somewhat unusually, the county boundary at this point is drawn so that the lake itself lies in the county of Gwynedd, but all the surrounding land lies in Conwy County Borough.

<span class="mw-page-title-main">Llyn Eigiau</span> Reservoir in Snowdonia, Conwy, Wales, UK

Llyn Eigiau is a lake on the edge of the Carneddau range of mountains in Snowdonia, Conwy, Wales. The name Eigiau is thought to refer to the shoals of fish which once lived here. Early maps refer to it as Llynyga. It is thought that a small number of Arctic char exist in the lake after they were transferred here from Llyn Peris, and certainly it is one of the few lakes in Wales to have its own natural brown trout. The lake is surrounded by mountains including Pen Llithrig y Wrach.

Less than a kilometre to its south lies the smaller Llyn Melynllyn. Cliffs rise steeply from the lake edge up to the summits of Garnedd Uchaf and Foel Grach, giving it a dark brooding appearance - hence its name.

Llyn Conwy (SH780462) is a lake in the county of Conwy in central north Wales. It is the source of the River Conwy which, on flowing south out of the lake, swings round to then generally flow in a northerly direction for a distance of some 27 miles (43 km) to its discharge in Conwy Bay. Llyn Conwy lies at a height of about 1,488 ft, with a maximum depth of 16 feet, and is by far the biggest lake of the Migneint moors, an extensive area of blanket mire with high rainfall - about 260 cm p.a. There is a view of Arenig Fawr.
