A balanced Scottish river profile. Early season nymphs and spiders, then more dry-fly and emerger fishing as hatches strengthen on steadier glides and richer water.

About this water

The Blackadder is one of the Tweed's lower tributaries — it drains the Berwickshire Merse country and joins the Whiteadder near Allanton before both flow into the Tweed near Berwick. It is a slow, meandering, farmland river with a good head of wild brown trout, better-than-average insect life, and the kind of quiet Borders character that means you often fish a whole day without seeing another angler. The fishing is best in May and June when the olives are on, and from late August through September when the grasshoppers start to fall on the water. Day tickets through Duns & District Angling Association. Nothing dramatic, but a genuine pleasure to fish if you like your rivers quiet and your trout wild.
