Talsperre Zeulenroda, Water reservoir in Zeulenroda-Triebes, Germany

Talsperre Zeulenroda is a reservoir on the Weida river, impounded by a 307-metre-long rockfill dam about 35 metres high, built from diabase rubble with an inclined clay core reaching 12 metres thick. A 49-metre-high water extraction tower stands in the lake, linked to the shore by a 105-metre prestressed concrete bridge. The reservoir holds a maximum water depth of 30.1 metres.

The dam was built between 1968 and 1975 as part of East Germany's water management and infrastructure expansion plans. The project was created during a period when such large structures were important for energy supply and water use.

The nickname "Zeulenrodaer Meer" (Zeulenroda Sea) comes from the reservoir's size in the Weida valley. Since the drinking-water protection zone was lifted on 1 September 2012, the lake has been used for tourism. The 2006-certified circular hiking trail, extended by 25 km for recertification in 2009, is a local point of pride.

The 307 m dam wall can be crossed on foot, and a 105 m prestressed concrete bridge links the shore to the 49 m water extraction tower. A circular hiking trail around the reservoir was certified as a "Qualitätsweg Wanderbares Deutschland" in 2006, with 25 km added at recertification in 2009. The DSV Nordic Walking Park "Thüringer Vogtland" in the Weidatal offers four marked routes of differing difficulty.

The 49-metre water extraction tower is not submerged: a 105-metre prestressed concrete bridge links it to the shore. The reservoir's maximum depth is 30.1 metres, so the tower rises well above the waterline.
