Lakes

A number of lakes are found in the various cwms of the Snowdon range.

  • Llyn Llydaw – 1,430 feet (440 m) high, 110 acres (45 ha) – lies in Cwm Dyli, Snowdon's eastern cwm, and is one of Snowdonia's deepest lakes, at up to 190 ft (58 m) deep. Various explanations of its name have been put forward, including lludw ("ash"), from ashen deposits along the shore, to Llydaw ("Brittany"). It contains evidence of a crannog settlement, and was the location of a 10-by-2-foot (3 m × 0.6 m) dugout canoe described in the Cambrian Journal in 1862. The lake is significantly coloured by washings from the copper mines nearby, and is used by the Cwm Dyli hydroelectric power station, which opened in 1906. The lake is crossed by a causeway, built in 1853 and raised in the 20th century to prevent the causeway from flooding frequently.
  • Glaslyn – 1,970 feet (600 m) high, 18 acres (7.3 ha) – lies higher up Cwm Dyli than Llyn Llydaw. It was originally called Llyn y Ffynnon Glas, and has a depth of 127 feet (39 m). For a long time, it was believed to be bottomless, and is also the location for various myths.
  • Llyn Ffynnon-y-gwas – 1,430 feet (440 m) high, 10 acres (4.0 ha) – lies in Cwm Treweunydd, Snowdon's north-western cwm, and is passed by the Snowdon Ranger path. It was enlarged by damming for use as a reservoir for use by slate quarries, but the level has since been lowered, and the lake's volume reduced to 24,000 cubic metres (850,000 cu ft).

Other lakes include Llyn Du'r Arddu below Clogwyn Du'r Arddu – 1,901 feet (579 m) high, 5 acres (2.0 ha), Llyn Teyrn near Pen-y-pass – 1,237 feet (377 m) high, 5 acres (2.0 ha), and several smaller pools.

Famous quotes containing the word lakes:

    If the fairest features of the landscape are to be named after men, let them be the noblest and worthiest men alone. Let our lakes receive as true names at least as the Icarian Sea, where “still the shore” a “brave attempt resounds.”
    Henry David Thoreau (1817–1862)

    What is most striking in the Maine wilderness is the continuousness of the forest, with fewer open intervals or glades than you had imagined. Except the few burnt lands, the narrow intervals on the rivers, the bare tops of the high mountains, and the lakes and streams, the forest is uninterrupted.
    Henry David Thoreau (1817–1862)

    I walk toward one of our ponds; but what signifies the beauty of nature when men are base? We walk to lakes to see our serenity reflected in them; when we are not serene, we go not to them. Who can be serene in a country where both the rulers and the ruled are without principle? The remembrance of my country spoils my walk. My thoughts are murder to the State, and involuntarily go plotting against her.
    Henry David Thoreau (1817–1862)
