Tärendöälven

Tärendöälven is a river in Norrbotten County, northern Sweden. It is best known as the bifurcation that links the Torne River system with the Kalix River system.

For salmon anglers, Tärendöälven matters mainly because of what it shows about the wider river network. It carries part of the flow from Torneälven toward Kalixälven, so it is more of a connector between two major salmon systems than a first-choice salmon river.

For most trips, the key question is whether Tärendöälven fits into a wider Torne / Kalix plan or whether the main focus should stay on the main salmon sections of Torneälven and Kalixälven.

Tärendöälven is commonly given as about 52 km long. It branches off from Torneälven near Junosuando and flows southeast before joining Kalixälven near the village of Tärendö.

Tärendöälven is also often described as one of the largest natural bifurcations in the world. At the Junosuando / Tärendö bifurcation, hydrological sources note that an average of about 57% of the flow is drawn off toward Kalixälven, equal to about 83 m³/s. This makes the river unusual not only locally, but also in a wider hydrological context.

For salmon-focused planning, this matters mainly as background for understanding the region. Tärendöälven explains the physical connection between the Torne and Kalix systems, but the main salmon plan should usually start with Torneälven or Kalixälven themselves.

Fishing on Tärendöälven depends on the exact permit area and local rules. Local permit waters may include salmon, trout, grayling, whitefish, pike, perch, and ide, but the role of each species can vary by section.

For salmon planning, the most important point is to check current salmon regulations, local permit rules, permit availability, water level, and whether salmon fishing is realistic on the exact stretch you are considering.

To understand Tärendöälven in practice, start with the river connection, local permit waters, and your target species.

Junosuando bifurcation area

This is where Tärendöälven branches off from Torneälven. It is the key hydrological reference point for understanding the Torne / Kalix connection.

For salmon planning, this area is mainly background rather than the first place to choose.

Lautakoski and Koijuniemi

These are useful local reference points along the river. They help place Tärendöälven as a short but important link between the Torne and Kalix systems.

If you are checking access or local fishing, these areas can help narrow the plan.

Tärendö village area

Tärendö is where the river joins Kalixälven. Local waters around the village can be relevant for mixed fishing and for understanding where the bifurcation returns water into the Kalix system.

For a salmon-focused trip, this area should be checked together with Kalixälven’s own salmon sections and current rules.

Torne / Kalix connection

Tärendöälven connects two of the most important salmon river systems in northern Sweden. It is not the main salmon destination, but it helps explain how the wider river network works.

For trip planning, the main salmon plan should still start with Torneälven or Kalixälven.

Tärendöälven stands out because it is not a normal tributary. It is a bifurcation: water leaves Torneälven and flows through Tärendöälven into Kalixälven.

That makes the river important when looking at the wider salmon landscape of northern Sweden. It explains why the Torne and Kalix systems are physically connected, and why planning in this region should not always treat the rivers as completely separate.

In practice, Tärendöälven should be planned differently from Torneälven or Kalixälven. It is not usually the first river to choose for a salmon-focused trip, but it can matter if you are building a broader plan around both river systems.

If salmon is the main goal, start with the main salmon sections of Torneälven or Kalixälven first. Tärendöälven can then be checked as a supporting area, especially if your plan also includes trout, grayling, whitefish, or local fishing around Tärendö.

Tärendöälven makes the most sense if you are already planning around the Torne and Kalix systems. It is usually not the first choice when salmon is the only goal, but it can be useful if you want to understand the region, add local fishing, or include mixed species in the trip.

Junosuando, Lautakoski, Koijuniemi, and Tärendö are useful reference points when checking access and local waters.
