A small (less than 1 acre) man-made lake formed to provide water to work a near-by quarry. Fish were introduced and did well in it, the best attaining around half a pound in weight. It is a 20 minutes walk from Blaenau Ffestiniog.

UPDATE: the lake is very shallow now and may be fishless.

As of 2024, tickets can no longer be booked online with The Fishing Passport. Information on local ticket outlets can be found on the clubs website.
