Agger Dam

The Agger Dam stretches 225 meters across the Agger River valley, rising 45 meters high to create a reservoir of 20.5 million cubic meters.

Construction of the dam commenced between 1927 and 1929 following initial planning from 1900 to 1904 to address increasing energy demands and flood prevention.

The dam exemplifies German engineering progress during the early 20th century, marking a period of substantial infrastructure development in North Rhine-Westphalia.

Visitors can access numerous hiking trails around the reservoir, which spans 150 hectares and includes facilities for sailing, rowing, and designated diving areas.

In 1967, the reservoir required complete drainage for repairs, leading to the addition of a 12-centimeter bitumen layer and 40-centimeter concrete layer for reinforcement.
