When looking at this region, there is a noticeable shift in which flies are used and which are not, resulting in a slightly different pattern compared to other areas previously analyzed.
Neither Flekkudalsá nor Blanda are included in this analysis, as there was not enough catch data available to ensure reliable results.
The data clearly shows that in rivers such as Haukadalsá and Miðfjarðará, the top ten flies account for over 50% of the total catch, highlighting how dominant a relatively small selection of flies can be.
Conclusion
The data from Northwest Iceland clearly shows that while a wide range of flies are used, success is heavily concentrated around a relatively small group of proven patterns.
Flies like Sun Ray Shadow, Frances, and Collie Dog consistently appear across multiple rivers, while techniques such as hitch fishing also play an important role under the right conditions.
At the same time, each river has its own characteristics, meaning that understanding local patterns can make a significant difference in results.
For anglers, this highlights a simple but important point: choosing the right fly for the right river can often be the key to success.
