Diemelsee Dam

Highlight • Monument

The original purpose of the Diemel Reservoir – in conjunction with the Eder Reservoir – was to balance the water levels of the Weser and the Mittelland Canal. This was intended to improve shipping conditions on the Upper Weser. Since 1960, the primary focus has been on balancing the Upper Weser.

The approximately 42-meter-high dam, completed in 1924, and the power plant building are now listed as historical monuments. The view of the dam is impressive.

The dam is also considered one of the Sauerland's spiritual places. It symbolizes the theme of "power and strength."

Way from the hiking car park Florenbicke located directly on the Diemelsee. Signage is good, step resistance, sturdy shoes and a certain degree of resilience are recommended.

Blue Lake Messinghausen

Unfortunately only the view from above is possible, everything is privately owned and the operators (diving center) do not like visitors😔🧙

From the Diemelsteig you will have wonderful views of the Diemelsee. But be careful: the viewpoints are not always directly on the path, but it is always worth taking the small detour.

Here you can easily get to the foot of the dam, which is not possible with every dam.

The Helminghausen lido is located in the town of Diemelsee in Hesse, where swimming and paddling around the large water slide and the floating pontoon is popular. The 290 meter long sandy beach and the large lawn behind it invite you to relax, small children play in the sand and in the shallow shore water or on the playground equipment and a natural history trail explains life at the lake. All in all, the Diemelsee is a worthwhile destination.
