The construction of the Diemelsee-Staumauer was decided in 1905 and started in 1912, but had to be interrupted due to the First World War and was only completed in 1924.
It was built from barely weathering greenstone (diabase), which was quarried just below the summit of Eisenberg, which rises to the right of the dam wall.

The Diemel dam is not used to supply drinking water. Its function is to supply the feed water for the Mittelland Canal when the water level of the Weser is low. Another purpose is flood protection.
The Diemelsee-Staumauer and the hydroelectric power station are now listed buildings.
