Llyn Clywedog

Llyn Clywedog was created in the mid 1960’s to control the flow of water into the River Severn, preventing flooding in winter and supplying a regular supply in the summer.

The lake itself is more than 6 miles (9.7Km) long, 216 feet (66m) deep at its maximum and has a surface area of over 615 acres which is equivalent to 230 football pitches. The reservoir holds the equivalent of 264 billion glasses of water.

The River Severn is Great Britain’s longest river at 220 miles (354Km) long from its source high on the slopes of Plynlimon (Pumlumon) mid Wales to when it finally discharges into the Severn Estuary below Gloucester.

Llyn Clywedog provides an ideal habitat for a great variety of wildlife. Red Kites and Buzzards are an almost daily sight; Peregrine Falcon and Osprey have also been seen around the lake. Goosander, Teal and Great Crested Grebe are common on the water while in the hanging sessile oak woodland and more exposed open hillside can be seen numerous flocks of Long Tailed Tits as well as Bullfinches, Pied Flycatchers and Stonechat.

Butterflies are abundant throughout the summer months and in the autumn the woodland and lakeside are carpeted in the colours of a rich array of fungi.
