Olef Reservoir

Highlight • Lake

The Oleftalsperre was built in 1954-59. Due to cracks, the barrier had to be reinforced twice afterwards. Since 1965, the barrier has been used for drinking water, energy production and water level regulation for the Olef.

The height of the dam wall above the valley floor is 54.6 m, the storage capacity of the lake 19.3 million cubic meters.

Oleft Reservoir Peninsula

Highlight • Lake

Not easy to get to the lake or even to take a picture. If you have the opportunity, you should take advantage of it.

November 1, 2022,Nordeifel: Kleine Sonnentour am Nordufer der Oleftalsperre

The final tour for our short vacation to the stars of the Eifel - instead of the circular route, we decided to go the same way back and forth... always nice on the go in the sun ☀️

October 2, 2025,Eifel: Oleftalsperre

We used the long weekend for another tour in the Eifel region – this time with a rented campervan. 🚐 The first day couldn't have been more beautiful: We began our adventure under bright blue skies and mild temperatures. Our first stop was the Oleftalsperre (Oleft Dam). 🚏
