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

Small northeast freestone river with a specialist reputation — one of Scotland's finest sea trout fisheries, with larger fish than you expect from a river of this size. Mandatory catch-and-release applies. Declining Atlantic salmon populations are Category 3 under Scottish Government classification; every fish returned matters. Summer sea trout (June–September, peaking July–August) dominate; salmon present but secondary. Brown trout in the upper reaches. The lower river is tidal and the estuary (a nature reserve) concentrates fish. Fish sea trout with smaller dries and nymphs in broken water; night fishing productive. Accessible fishing relative to famous neighbours.
