Bala Lake
Llyn Tegid (, ), also known in English as Bala Lake (), is a lake in Gwynedd, Wales. The name Tegid may be related to Welsh "teg", meaning "fair". It was the largest natural body of water in Wales before its level was raised by Thomas Telford to help support the flow of the Ellesmere Canal. It is long by wide. The River Dee runs through it and the waters of the lake are deep and clear. The town of Bala sits at its north-eastern end and the narrow gauge Bala Lake Railway runs for along the lake's south-eastern shore, and continues south-westward to the village of Llanuwchllyn (whose name means "church ['llan'] above ['uwch'] the lake ['llyn']").
