The River Fane is a beautiful and productive angling river flowing through Counties Monaghan, Armagh, and Louth in Ireland. Originating from a series of smaller tributaries — including the Frankfort and Mullaghaduff rivers — that drain into Lough Muckno near Castleblayney, Co. Monaghan, the Fane proper begins at Lough Ross, which straddles the border between Monaghan and Armagh. From there, the river travels approximately 60 kilometers in a southeasterly direction before emptying into the Irish Sea at the seaside village of Blackrock, Co. Louth, within Dundalk Bay SAC. The catchment covers approximately 140 square kilometers, with underlying geology comprising mostly mudstone, greywacke, and conglomerate, and the surrounding land use dominated by agriculture. The Fane is a clear, wading river with a reputation for wild brown trout, salmon, and sea trout, and its upper stretches in particular offer some of the finest wild trout fishing in the east of Ireland.
