River Foyle

The River Foyle is a river in west Ulster in the northwest of the island of Ireland, which flows from the confluence of the rivers Finn and Mourne at the towns of Lifford in County Donegal, Republic of Ireland, and Strabane in County Tyrone, Northern Ireland. From here it flows to the city of Derry, where it discharges into Lough Foyle and, ultimately, the Atlantic Ocean.

The total length of the River Foyle is 32 km (20 mi).

The river separates part of County Donegal from parts of both County Londonderry and County Tyrone. The district of County Donegal that borders the western bank of the River Foyle is traditionally known as the Laggan. This district includes the villages of St Johnston and Carrigans, both of which are nestled on the banks of the River.

Tributaries
The Burn Dale (also known as the Burn Deele or the River Deele) flows into the River Foyle on the northern outskirts of Lifford, while the Swilly Burn flows into the Foyle near Porthall, a hamlet between St Johnston and Lifford. St Johnston Burn flows into the Foyle at St Johnston, while Flushtoun Burn flows into the river on the southern outskirts of St Johnston. Carrigans Burn flows from Port Lough, and enters the Foyle on the southern outskirts of Carrigans. Both the Burn Dennet and the Glenmornan River flow into the Foyle just to the north of Ballymagorry, entering the river a short distance to the north of Corkan Isle.

Fishing

The river is primarily renowned as a salmon and sea trout river and the fishing season runs from 1st April to 20th October. There is a variety of ownerships wherein some waters are in public ownership, some are private and others are leased to clubs.
