Pressegger See, Lake in Hermagor-Pressegger See, Austria.

Pressegger See is a lowland lake in Carinthia, set in the Gail Valley near the town of Hermagor. It is surrounded by wooded slopes and has a flat, grassy shore with wide reed beds running along much of its edge.

The Gail Valley, where the lake sits, was home to settlements long before written records, as shown by finds in the area. The region later became part of the Duchy of Carinthia and, over time, fell under Habsburg rule.

The lake's Slovene name, Preseško jezero, is still used alongside the German one in a region with a bilingual Carinthian Slovene population. The wet meadows beside the water were once the basis of the Gailtal horse breeding for which the valley was known.

Several bathing spots around the lake are easy to reach from spring through early autumn, with room to swim and rest. A path runs around the water and works well for walking or cycling at an easy pace.

The reed beds along the western and eastern shores form the largest connected stand of Phragmites australis in Carinthia, growing up to 3 m tall. Among them live reed warblers, Savi's warblers and little bitterns, and the fen woods behind hold the fen orchid Liparis loeselii, rare in Central Europe.
