The river

The Gaula runs from the Dovrefjell plateau to the Trondheimsfjord at Melhus, and it has been Norway's benchmark salmon river for a century. Its catch statistics are published in detail and are unusually honest, which is why serious salmon anglers trust it. It is a big, wide river with a gravel bed, and it produces a lot of fish between 8 and 15 kg alongside a strong run of smaller grilse.

On this river

Night fishing under the midnight sun

At 63 degrees north the July nights never go fully dark, and the Gaula's salmon take best between 22:00 and 02:00. Fish a small dark tube fly on a floating line, work the tail of the pool first, and keep your casts short — in the half-light a fish that has felt the line is finished for the night.

Reading high water for big fish

In June, the Gaula's big salmon run close to the bank because the midstream current is too strong to hold in. Fish the inside of the bend and any gravel shelf that is no more than 1.5 metres deep, and use a fly that is big enough to be seen in peaty water — a #2 or #4 rather than a #8.

The honest catch report

Norwegian salmon management depends on anglers reporting every fish, including released ones. The Gaula's vald require a return at the end of the day and the statistics are public. Failing to report is not a victimless shortcut — it is what causes rivers to be closed early for everyone.

Licence and rules

Norway requires a national fishing licence (fiskeravgift) for anyone over 16, plus a local day or season card for the specific stretch. The Gaula is divided into a large number of private and club-owned vald, and most sell day cards on site or online. Crucially, Norway allows catch-and-release only in the lower river after the quota is filled and the season can close early with 24 hours' notice if the run is weak.

How does the water behave?

The Gaula is fed by snowmelt from Dovrefjell and stays high through June, then drops steadily through July to a clear low-water condition in August. The best fishing shifts the other way: in June the big fish are caught in high, cold water on large flies fished near the bank; by August they are in the pools and taking small flies. The river can rise again after summer rain and that is usually the signal for a fresh run of fish.
