The fishing on the River Mourne starts in earnest from late May, peaking through June and July, although there are the occasional spring fish which may be encountered in April and early May. The River Mourne also has a strong run of back end autumnal fish and this can make good sport in September and October. Like other rivers in the Foyle system, the River Mourne gets a decent run of sea trout from June onwards. The average weight of these sea trout is around the pound mark with the occasional bigger fish being caught.
The best time to go salmon fishing is from April to September, with the peak fishing season occurring in June and July.
The river is known for its salmon and trout, and there are several fishing beats available for angling. It's recommended to check with local fishing guides or associations for the most up-to-date information on fishing regulations and recommended fishing spots. You do need a fishing licence to fish in addition to your permit.
The surrounding area of the River Mourne is rich in natural beauty and offers a variety of outdoor activities. The Sperrin Mountains, which are located nearby, offer stunning views and a range of walking and hiking trails. The town of Strabane, which is situated on the banks of the River Mourne, has a rich cultural heritage and is home to a number of historical landmarks and museums.
The River Mourne rises to the north west of Newtownstewart at the confluence of the Derg and Strule.
Above this junction it is called the River Strule, one of the myriad of tributaries which comprise the Mourne. From the confluence with the River Derg, the River Mourne continues to flow northwestward to join the River Foyle at Strabane, a total journey of about 13km. Although it is a short river, the River Mourne is a big fast flowing river. As far as reputations go, the River Mourne can rightly be compared to the other great Irish salmon rivers such as the Blackwater, the Lower Bann, the Moy and it's sister river, the River Finn. It is estimated that over 9,000 salmon annually enter the Mourne.
The River Mourne, unlike it's nearest rivers, is not a spate river but in keeping with other salmon rivers fishes best as the water drops and fines down after a flood. Given the size of the river and the catchment it usually takes 3 to 4 days for the river to become fishable again after such a flood.
