Llyn Parc
reservoir in the United Kingdom
Llyn Parc (also known as "Llyn y Parc") is a lake in the Gwydir Forest in North Wales.
Lying at a height of 664 feet, it covers an area of 22 acres (89,000 m2), and is long and narrow in shape.
A natural lake, the building of a dam at the southern end raised the level to provide water to drive machinery at the nearby Aberllyn lead and zinc mine, which in 1900 employed some 200 men. The outflow of the lake today passes the ruined remains of the mills before joining the River Conwy.
To the west of the lake are the remains of a high wall, built by French Napoleonic prisoners of war, to keep deer within the Gwydir High Park.
In 1938, when a large forest fire destroyed parts of the forest, it was hoped that Llyn Parc would act as a natural fire break. The fire, though, was so fierce that it crossed from one side to the other.
The high (though reducing) level of lead in the water means that there are no fish in the lake.
Some sources quote that the area around Llyn Parc is reported to be one of the few remaining strongholds of the red squirrel. This is not so, confusion having arisen between this location and the similarly named "Llyn Parc Mawr" at Newborough on Anglesey.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Llyn Parc”, the useful work is to connect “reservoir in the United Kingdom” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 27, 2026. The linked authority identifier is Q3405732. Authority coordinates are 53.113, -3.806. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1900 and 1938.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
