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.

Dreiborn Plateau

Highlight • Natural Monument

A special treasure of the Eifel National Park is the open land on the Dreiborn plateau. Here there are grasses, broom, hawthorn bushes and many animal species that need exactly that. The endangered skylark, for example, lives and breeds in the open landscape. That is why it is so important that we humans only move on the marked paths and do not disturb the breeding sites of the sensitive species off the paths 🐣. Over time, the open land grows over with bushes and individual trees 🌳. To ensure that the open land does not disappear completely, certain areas are mown late in the year (after the breeding season). According to international criteria (IUCN Category II), such "management" is permitted in the long term on up to 25% of the area of a national park. From 2034, the Eifel National Park is even expected to manage with less than 20% of the area in order to preserve the Dreiborn plateau as a valuable habitat, among other things.

The most important "rules of the game" for protecting nature: Stay on official paths, don't light fires or make noise, keep dogs on a leash & take your rubbish with you. Thank you for your understanding! 💚
