Burn Dennett (or Dennet) is a medium sized (5-20 metres width) spate river. Rising on the northern flanks of the main Sperrins ridge, the river drops northwards through Donemana, swinging west through native woodland and pasture before meandering across broad flats to reach the River Foyle upstream of the walled city of Derry/Londonderry. Sea trout peak June to August, with grilse best fished for in July and August and salmon in August and September with the wild brown trout being most active at the start of the season.
Throughout it’s length the Dennet is relatively easy to wade with a shale/gravel bottom interspersed with the occasional larger rocks. Due to the fact it is a spate river the depth and colour can change a wading staff and chest waders are highly recommended. The Dennet also has the only disabled angling point in the catchment that includes an accessible toilet – see the map for details. Day and season tickets available from the Dennett Anglers Association, who control the fishing rights for the entire river and it’s tributaries.
Please note that whilst every attempt has been made to ensure the accuracy of angling club and associations boundaries it is essential you consult the club or association to confirm their upper and lower limits.
