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 1,164 feet (355 m) above sea level. The lake is long and narrow, measuring nearly 2 miles (3 km) long and about a third of a mile wide, and covers an area of 269 acres (1.1 km2). It has a mean depth of 109 feet (33 m) and at its deepest has given soundings of 229 feet (70 m), this being some 45 ft (14 m) greater than its natural depth, the water surface having been raised twice by the building of dams.
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.

The lake is surrounded by mountains including Pen Llithrig y Wrach.

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.

The Afon Gwyrfai is a short river in Gwynedd, Wales. For half of its length it flows through Snowdonia National Park. Exiting Llyn y Gader it flows north through the small village of Rhyd-ddu to enter the southeastern end of Llyn Cwellyn. Downstream of the lake it flows northwest past Betws Garmon, leaving the national park and continues to the southern edge of Waunfawr. It then turns slightly west to flow on to Bontnewydd beyond which it turns slightly south to enter Foryd Bay. The tidal channel within the bay flows north into the western end of the Menai Strait. Principal tributary streams include the Afon Treweunydd which contributes water from the reservoir of Llyn Ffynnon-y-gwas and from the lakes of Llyn Glas, Llyn Coch and Llyn Nadroedd in Cwm Clogwyn immediately west of the summit of Snowdon. The tidal channel of the Gwyrfai within Foryd Bay also accepts the flow of the left bank tributaries, the Afon Foryd, Afon Rhyd and Afon Carrog. The river is shadowed by the line of the Welsh Highland Railway for much of its length, and by which it is crossed four times.
