Conway River

Conway River takes its rise from Lake Conway on the borders of the counties of Merioneth, Denbigh, and Carnarvon. Flowing first N.E., then N.W. and N., it divides the two latter counties, drains the picturesque Vale of Conway, and after a course of 30 miles discharges its waters into Beaumaris Bay. It is navigable for vessels of 100 tons for a distance of 10 miles from its mouth.
