The lake covers an area of only {{convert|33|acre|m2}}, yet is extremely deep - it reaches to a depth of 189 feet (58 metres). 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. The lake has a dam, originally built in 1881, to increase its water capacity, but it has been altered several times since. As a reservoir Dulyn (along with Melynllyn) provides water for the town of Llandudno. The pipes cross the River Conwy at Tal-y-Cafn bridge. The outflow from the lake is called Afon Dulyn, and this stream also feeds water into neighbouring Llyn Eigiau. Afon Dulyn flows north-east, passing Tal-y-bont before joining the River Conwy. In June 1284 the lake was the setting for the court of King Edward I of England for victory celebrations, following his defeat of Llywelyn ap Gruffudd, with an Arthurian theme, including the King’s 45th Birthday[1] A number of superstitions are connected with the cwm, which has also been the site of a number of aeroplane crashes.[2] In 1944 an American Dakota aircraft crashed into the cliffs above the lake killing all four crew.[3] References1. ^Marc Morris. 2009.
