Glenelly River fishing venue photo

A Sperrin Mountains tributary of the Owenkillew, flowing west along the long, linear Glenelly Valley south of Sawel Mountain — one of the principal fault lines in the range — through the village of Plumbridge before joining the Owenkillew near Newtownstewart (itself a Strule/Mourne tributary).

How to fish it · for Atlantic Salmon
When
Morning into early afternoon.
Where
Pool tails, steadier runs, and any water with pace.
Method
Fish a sensible line-and-fly combination for the height and pace of water.
Kit
13 ft #8/9 double-hander in spate, 10 ft #8 single in low water. Floating line plus a fast-sink tip. 12–15 lb fluoro tippet.
Why this works
Poor — water temperature is working for you, but water clarity is the limiting factor today.

Ranked for today
Atlantic Salmon fly box

Boyne/Slaney summer grilse: fish lie shallow at the tail and neck of pools, so a single hook fished just sub-surface won't snag and covers a taking fish better than a treble. Keep dressing sparse — a small silver stoat, blue charm or Ally's shrimp style in a light build fits.

About this water

A Sperrin Mountains tributary of the Owenkillew, flowing west along the long, linear Glenelly Valley south of Sawel Mountain — one of the principal fault lines in the range — through the village of Plumbridge before joining the Owenkillew near Newtownstewart (itself a Strule/Mourne tributary). A medium-sized river carving through soft glacial moraine and alluvium, with peaty marsh pockets on the valley floor; otters are resident. Better known for salmon and sea trout than for its wild brown trout, though the trout stock is good. Loughs Agency-managed as part of the wider Foyle system. Atlantic salmon are managed under DAERA and Loughs Agency conservation byelaws, with mandatory catch-and-release on many waters; check current rules before fishing.
