About this water

The Bush is Northern Ireland's premier salmon river — compact, intensely managed by DAERA, and with one of the most studied salmon populations in the British Isles thanks to the Bush salmon research station. It runs from the Antrim basalt plateau to the north coast at Bushmills, close to the Giant's Causeway. Three managed beats (New, Town, Leap) rotate anglers through pools. Spring salmon from March, building through April–May; grilse from June. The river fishes best 12–24 hours after rain — it rises fast off the basalt and clears quickly. Small doubles (10–14) on floating line in summer; larger tubes on sink-tips for spring fish. The unrestricted public stretch below the weir offers free fishing. Book beats through DAERA or Bushmills Salmon Anglers. Volcanic bedrock underlies this river. Atlantic salmon are managed under DAERA and Loughs Agency conservation byelaws, with mandatory catch-and-release on many waters; check current rules before fishing.

Hatches & food

No venue-specific hatch data yet; as a basalt-country spate river, expect flood-driven stonefly and terrestrial activity to outweigh any reliable upwing hatch — a general expectation, not a confirmed observation.
