Tributaries flow from every point of the compass: the Lower Bann, which drains the lake and runs north to Lough Beg (finally reaching the sea north of Coleraine), contains some huge trout, including the dollaghan, unique to these waters. Similar to salmon – which are also common – dollaghan grow by three pounds every year and can be caught by spinning, worming and fly-fishing: the Ballinderry Black and the Bann Olive are famous flies derived from this region. The best fishing is from mid-July to October but you will need a Fisheries Conservation Board Rod licence, available from tourist offices. Information on day-tickets for fishing and specialist boat-trips, respectively issued and run by the Lough Neagh Angling Association, can also be obtained from the tourist office.
