A friends dad told me a story about the lake near Ashley Park. One day people where cutting barley in the field where the lake is and they struck a spring. They thought great some fresh water. However the spring didnt stop flowing and this is how the lake was formed. Im not sure if this is folklore or whether it is meant to be true but there are crannogs in the lake so it is likely the lake is their for at least 1000 years. Intriguingly the name of the lake is Lough Eorna or the lake of barley.
