The Glenelly rises high in the Sperrin Mountains, running westwards along a glaciated valley to meet the Owenkillew River downstream of Plumbridge at "The Meetings". The Owenkillew runs to meet the River Strule near Newtownstewart. The Glenelly is a spate river (5-20 meters wide) that has small wild brown trout and occasional larger specimens, but it is better known for salmon and sea trout fishing. Sea trout is best in June and July while grilse and salmon may be present from mid-June if there is sufficient water - however, salmon fishing is often best from August to October.
The Owenkillew rises in the centre of the Sperrin Mountains and makes its way westwards to the River Strule through mountain, rough pasture and then broad "holms" (or flood plains) in its lower reaches. This spate river is noted for its run of sea trout, good grilse and salmon from mid-July. The medium width (5- 20 meters wide) Owenkillew also holds good brown trout.
The Quiggery Water winds through pasture and wetland to meet the Drumragh upstream of Omagh. It enjoys substantial mayfly hatch in the middle of May with trout between 2lbs and 3lbs (0.91-1.4kg) taken every year! Spate can bring on the bigger fish in the evening.
The Roe rises high above the Glenshane Pass, dropping rapidly to Dungiven. The spate river then makes its way through the beautiful Roe Valley Country Park before meandering across the broad Lough Foyle lowlands. Sea trout fishing starts the season on the Roe, with fine runs from late June to August. Salmon fishing is at its best from August onwards, proving most productive in spate conditions in the mid section of the river.
The Strule forms at the confluence of the Drumragh and Camowen rivers in the centre of Omagh. It is a big river (20 meters plus width) and runs northwards for twelve miles, bounded by rich pasture and occasional cereal crops. Along its length it is joined by the Fairy Water and the Owenkillew before meeting the Derg below Newtownstewart to form the River Mourne.
