Åsunden Östergötland, Large lake in Östergötland, Sweden

Lake Åsunden is a large body of water in southern Östergötland with clear waters and considerable depth throughout. The lake occupies several thousand hectares and connects to a regional canal system.

This waterway was part of an important transport system used in the 1800s for moving timber and goods during Sweden's industrial growth. Canal connections shaped the economic role of this region for decades.

The lake sustains local fishing traditions with perch, pike, and other species that fishermen regularly pursue. This waterway has served fishing communities for generations as both a food source and livelihood.

Åsunden is the southernmost and highest-lying of the lakes linked by the Kinda canal, which begins here and runs 80 km to the Göta canal. The lake is reached via the canal lock at Rimforsa, where it also connects with Järnlunden, and via the Skedevid canal to Ämmern. A bridge at Råsö crosses a narrow section, dividing the water into Norra and Södra Åsunden.

The lake reaches exceptional depths that make it one of the deepest in the region. This depth creates varied habitats that support different fish populations.
