Llyn Alaw

Llyn Alaw

Llyn Alaw is a man-made reservoir on Anglesey, created in 1966 on existing marshland. Its name means "Lily Lake".

The reservoir is used to supply drinking water to the northern half of Anglesey and does so at a rate of 7.7 million gallons a day.

The catchment is largely agricultural and few notable rivers feed into the lake. The storage capacity is largely generated through trapping winter rainfall and drawing down the level in the summer months. The reservoir itself is 2.7 miles long with a surface area of 1.3 square miles, making it the largest body of water on the island, although on such a flat island it only ever reachs a depth of 17 feet.

For all that is is man-made, the lake is a fair lake in beautiful countryside. Recent developments have included the provision of nature conservation facilities and way-marked walks around the margin.
