Mülbener See, Artificial lake in Mülben, Germany.

Mülbener See is a 1.2-hectare reservoir in the Winterhauch area of the Odenwald, about 1.25 km east of Mülben in Waldbrunn. It is held back by the dam of a north–south forest path at 527 m above sea level, measures roughly 120 m by 115 m, and drains west through the Höllbach. Its eastern edge is silting up.

An older topographic map from the first half of the 20th century labels the spot "Mülbersee" and shows forest there, suggesting a lake had existed earlier and was dry at the time. Around 1980 the spruce forest in the hollow was cleared and the present lake was created behind a dam on a north-south forest path at 527 m above sea level.

The lake serves as a gathering spot where locals fish and walk along the banks during their free time. It has become part of the everyday rhythm of the community in Waldbrunn.

The site is easy to reach through marked parking areas and the paths around the lake are well maintained. The route suits relaxed walks and cycling trips at any time of day.

An older topographic map from the first half of the 20th century marks forest and the label "Mülbersee" at the lake's present site, so a pond probably existed there before and had dried out. The map's dashed outline and the note "Wldgmkg. Zwgbg." suggest the area then belonged to Zwingenberg. Around 1980 the spruce stand in the hollow was felled and the lake re-created.
