Although this river finds its way into the sea near Ayr, its tributaries gather their flow near the Borders of Kirkcudbrightshire, before nestling down into the six-mile-long run into Loch Doon.

It is a river of mixed quality and character. For a few miles below Loch Doon the river runs in turbulent fashion, then slackens off into sluggish water. Below Patna the river gathers pace, forming splendid salmon pools.

Aided by compensation water from hydro-electric operations at Loch Doon, the River Doon can. Have a fair summer flow when other waters are more than a little jaded. This boosts the summer sea-trout and grilse fishing and the Doon can provide excellent results in these respects. It is not a spring salmon river of any note.

The upper reaches offer roach fishing and though these fish are not plentiful, they can often be of specimen size.
