Dee, River, is the name of five rivers in either Britain or Ireland. The best known of these rivers rises in Wales at Lake Bala, in Gwynedd, flows through Clwyd, and then forms part of the border between Wales and England. It continues through Cheshire before it eventually empties into the Irish Sea. The river is about 70 miles (110 kilometers) long.
Scotland has two rivers called Dee. The longer one rises in the Cairngorm Mountains and flows mainly in Grampian Region and provides much of Aberdeen’s water. It empties into the North Sea at Aberdeen. Its lower valley is known as Deeside. The river is about 90 miles (145 kilometers) long. The shorter Scottish Dee rises in Loch Dee in Dumfries and Galloway Region and flows south into the Solway Firth. It is about 50 miles (80 kilometers) long.
England has a River Dee that flows into the River Lune in Cumbria. In the Republic of Ireland, the River Dee flows into Dundalk Bay in County Louth.
