The Annalee River winds through County Cavan in Ireland's northwest midlands, draining the south-eastern portion of the Erne catchment before joining the River Erne and Lough Oughter lake system near Butlersbridge, just a few kilometres northeast of Cavan Town. Fed by several tributaries including the Bunnoe, Dromore, Knappagh, Madabawn, Laragh, and Cavan Rivers, the Annalee is a picturesque, productive river system celebrated among Irish anglers for its outstanding wild brown trout fishing and its connection to the broader Erne pike fishery. The river has earned a strong reputation on the competition circuit, having hosted both the ITFFA Ulster River Championship and the All Ireland River Championship, events that showcased the river's remarkable trout stocks and consistent hatches.
