Southern Uplands - Rivers and Lochs

Rivers and Lochs

The region is drained by numerous rivers, the most important of which are Scotland's third and fourth longest, the River Clyde at 106 mi (171 km) and the River Tweed at 97 mi (156 km) respectively. Several significant rivers drain southwards into the Solway Firth and Irish Sea including (from west to east) the River Cree, River Dee, River Nith, River Annan and the River Esk.

There are numerous lochs in the Southern Uplands, particularly in the west. The largest is Loch Ken which arises from the damming of the Water of Ken. Several other lochs in Galloway are dammed such as Loch Doon, Loch Bradan and Clatteringshaws Loch though many smaller ones remain in a more natural state such as Loch Dee, Loch Enoch, Loch Grannoch and Loch Trool.

To the east of Moffat is the largest natural body of water in the Southern Uplands, St. Mary's Loch together with the adjacent Loch of the Lowes and nearby Loch Skeen. There are several other reservoirs in the vicinity including Megget Reservoir, Talla Reservoir and Fruid Reservoir whilst Daer Reservoir lies among the Lowther Hills.
