The Blackwater is a major Lough Neagh tributary flowing through Co. Armagh — a slow, deep lowland river with excellent brown trout and dollaghan runs. The dollaghan run (July–October) is the main draw. Brown trout are plentiful throughout. The river also holds pike and some coarse fish. Managed by local clubs with day permits. The Blackwater responds slowly to rain — plan for sustained wet weather rather than single showers.
No venue-specific hatch data yet; as a lowland main-stem river, expect a broad seasonal mix of upwings, sedges and midges typical of these slower Ulster rivers — a general expectation, not an observed hatch.
