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.

The Oleftalsperre is a rewarding destination for a tour around. Trips to Rocherath and Hollerath are also included, so you can also see something of the Eifel region.

Hiking
The picturesque Olefsee, a drinking water dam with a capacity of 20 million cbm, lies in the midst of beautiful forests. A circular route of 13.5 km runs around the Olefsee, which offers hikers or cyclists an inexhaustible source of relaxation. The dam wall of the drinking water dam in pillar cell construction is still unique in Germany.
