The Otra River: Norway’s Hidden Gem for Anglers
Flowing through Southern Norway, the 245-kilometer Otra River is the country’s eighth-longest waterway. It traces Route 9 before emptying into the sea near Kristiansand, the region’s vibrant capital.
The Otra’s diverse landscape shifts from rushing rapids to tranquil lakes, offering a dynamic fishing experience. Its lower 16 kilometers are a hotspot for migratory Atlantic salmon, sea trout, and wild brown trout, with over 6,500 kg of fish—94% wild salmon—caught in 2014 alone.
Beyond Vennesla, where migratory fish are halted by artificial barriers, the river transforms into a network of interconnected lakes and streams. Here, anglers find abundant wild brown trout—small in size but plentiful, ensuring nearly guaranteed catches.
A Vision for Sustainable Fishing
In June 2023, the Otra Fishing Association partnered with Fishby to introduce a "smart fishing license," granting access to 180 kilometers of the upper Otra system in Setesdalen Valley. This digital pass excludes migratory species but opens doors to pristine waters from Hartevatn to Kilefjorden.
While wild brown trout dominate, elusive American brook trout and the rare Bleka salmon—a dwarf species unique to Byglandsfjorden—add intrigue. South of Fennefossen, perch thrive, while minnows populate the higher reaches.
