About this water

The Roe is a compact, productive salmon and sea trout river flowing from the Sperrins to Lough Foyle near Limavady. One of the four statutory Foyle rivers managed by the Loughs Agency. Fast-draining basalt catchment — responds rapidly to rain. Salmon from April with grilse from June; sea trout from May. The lower river has deep pools; the upper is classic pocket water. Day permits through Roe Angling and local clubs. The O'Cahan's Rock and Falls pools are iconic.
