How to fish it · for Atlantic Salmon
When
Late June through mid-September. The Vatnsdalsá is a north Iceland classic — premium beats, wild salmon, named-pool tradition.
Where
Named pools through the Vatnsdalsá valley above the sea. The river is intimate; short casts and careful approach pay.
Method
Hitch tube on a floater is the Icelandic signature — small cone-head sizes 12 to 14, hitched across-and-down. Conventional small wets and tubes when the hitch isn't on. Single barbless mandatory; mandatory C&R on most beats.
Kit
11 ft switch or 10 ft #7/8 single-hander — most Icelandic beats reward short-rod accuracy. Floating line. 10 to 12 lb fluoro tippet.
Why this works
Good — water clarity is working for you, but time of day is the limiting factor today.

About this water

A north-west Iceland river in the Húnaþing/Vatnsdalur district. Better thought of as a salmon river with secondary trout value than as a trout-led destination. Volcanic bedrock underlies this river. Iceland's salmon are managed conservatively under operator and national rules — quotas, size limits and catch-and-release are widely applied; check the river's rules before fishing.

Under the surface

Vatnsdalsá winds more than forty kilometres down the Vatnsdalur, a glacial trough valley in north-west Iceland famous for being greener and more dotted with small grassy hillocks than anywhere else in the country. The river threads two lakes — Flóðið and Húnavatn — on its way to the Húnaflói coast, draining a broad upland catchment of dark volcanic rock and gravel. Salmon fishing runs over three beats and some twenty kilometres of clear, gentle, meandering water with more than four dozen named pools. The lowest, Hnausastrengur, is the river's jewel: the first stop for running fish and, by repute, the pool that holds more twenty-pound salmon than any other in Iceland. The gradient is easy and the wading kind on firm gravel through the meadow reaches — a river to be read carefully rather than waded hard.
