Nice path along the reservoir. You would like to jump in (but you're not allowed to). The road surface is very rough, so it's not easy to roll there.

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. Source: https://www.hellenthal.de/Tourism/Seeing Values/Oleftalsperre
