Myth & Folklore
Llyn Llech Owain (The Lake of Owen's Flag)
The lake is associated in legend to Sir Owain, a knight at Arthur’s court. Folklore suggests that this lake was created when a well overflowed on Mynydd Mawr. The well keeper was a man called Owain (Owen), and one day after letting his horse drink from the cool waters, he forgot to replace the large stone slab that capped the well. The water flooded out down the valley, and was on the verge of submerging the whole area when Owain glanced back and realised what was happening. He quickly galloped back, and rode in a circle around the well until the tracks left by his horse's hooves stopped the water flowing. Lakes created by overflowing wells seem to be a common motif in British folklore.
