Even on Fridays when the weather is nice there are hardly any people here, the occasional view of the dam is really beautiful.

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

The road around the reservoir is no longer so slippery, but still doable with a racing bike. The climb up from the reservoir through the forest is beautiful, as a descent less suitable.
