The Monaghan Blackwater
The Monaghan Blackwater rises near the Bragan mountains and flows in a south-easterly direction through Monaghan Town. It eventually joins the Ulster Blackwater Near Caledon. Angling is controlled by the Monaghan Anglers Association who regularly stock the river. This river contains a good stock of wild and stocked brown trout as well as an increasing number of Dollaghan, which are a strain of trout unique to Lough Neagh and which migrate into this river to spawn. They are extremely fast growing and provide excellent sport. Dollaghan are not a free rising fish and the angler should employ similar methods to sea-strout fishing including fly patterns. The best time to fish for Dollaghan is after sunset right through to early hours. All legitimate methods are allowed but the Association encourages and supports a policy of catch and release. Some of the more popular angling areas are upstream and downstream of Milltown Bridge, upstream and downstream of Rathconnell Bridge and Silver Stream area close to the confluence with the Ulster Blackwater.
