The Sound of Many Waters

With the widest catchment area of any river in Britain, the Tay drains much of the lower Highlands of Scotland. A vast network of lochs and smaller bodies of water feed the rivers Isla, Garry, Tummel, Almond and Earn, which all in turn flow into this mighty river as it cuts its way through the landscape. Reaching back to a prehistoric fish found near Balruddery in Perthshire, we follow its story through time to the present day, with detours to seek gold, clans, battles, forts, disasters, witches and whisky en route.
