A site proposed to the Society as a potential nature reserve and a 'breeding place for scarce creatures', primarily birds. Known as Llyn Llywenan, the lake is designated as a Site of Special Scientific Interest (SSSI), today. The largest natural lake on Anglesey island, it is host to a number of rare aquatic plants including eight-stamened waterwort, spring quillwort and needle spike-rush. It hosts a variety of overwintering wildfowl. Privately owned and run as a fishing lake.
