Eutersee, reservoir in Germany

Eutersee is a reservoir in the Odenwald, built in 1971 as a flood retention basin. It lies in the narrow valley of the Euterbach, which forms the border between Hesse and Baden-Württemberg, and is up to 210 m long and 65 m wide. The wooded eastern slope reaches the upper shore, while the western slope stops 25 m short. At the outflow side, the valley opens toward Badisch-Schöllenbach.

Built in 1971 as a flood retention basin, the Eutersee stores water during heavy rainfall to protect the surrounding valley. The state border between Hesse and Baden-Württemberg runs through the lake, so its western shore lies in Hesse and its eastern shore in Baden-Württemberg. The Euterbach feeds and drains the basin, continuing about 700 metres downstream before joining the Schöllenbach.

The Euterbach flows through the lake from north to south, forming the Hesse–Baden-Württemberg border, and the water stays at 12–16 °C even in high summer because of the constant inflow of cold mountain water. A road with limited access runs along the eastern shore from Badisch-Schöllenbach. The youth campsite south of the lake, about 300 m away, is run by the Geo-Naturpark Bergstraße-Odenwald association and the town of Oberzent.

A fish ladder built into the dam allows fish to bypass the barrier and migrate to their spawning grounds upstream. A nearby campground spanning eleven hectares attracts families and groups seeking to spend nights surrounded by forest and meadows.
