The River Dee is a valuable asset to all of us living and working here. It provides a vital water supply to half of Aberdeenshire and all of Aberdeen City. The Dee is a specially protected SAC river, featuring Atlantic Salmon, Otter and Freshwater Pearl Mussel populations. Anglers from around the world visit the Dee to try and catch an Atlantic Salmon or Brown Trout, helping to support the local economy. The Source of the Dee is found high in the Cairngorms mountains within the Cairngorms National Park, and it flows 88 miles through Deeside, into Aberdeen Harbour. It is often termed 'Royal Deeside' due to the royal family making Balmoral Castle their summer home. You can learn more below.
