Map of Cairn Water, United Kingdom
The Castlefairn is joined by the Craigdarroch and then by the Dalwhat, both from its left, just below the village of Moniaive in the parish of Glencairn. The confluence of these streams forms the Cairn Water. The parish is named for the river valley. The river flows east past Kirkland, then southeast to Newtonairds, where it is joined by the Old Water to form Cluden Water. Cluden Water flows east and southeast to join the River Nith just north of Dumfries. The river once defined part of the boundary between Dumfriesshire to the east and Kirkcudbrightshire to the west.
