Baldeneysee, Reservoir in southern Essen, Germany

Baldeneysee is a reservoir in the south of Essen, formed by damming the Ruhr River and bordered by wooded shores on both sides. The water forms several bays and peninsulas that give space to sailing and rowing clubs as well as spots for swimming.

The reservoir was created in 1931 by damming the Ruhr River, with the aim of improving water quality for industrial use downstream. When heavy industry declined in the region, the area gradually became a destination for leisure and outdoor activities.

The name Baldeneysee comes from the original plan to place the weir at Baldeney Castle; because the gradient there was too low for economical power generation, the weir was built further downstream at Werden instead. Since 1933 the Weisse Flotte Baldeney has run passenger boats on the lake, and around 25 sailing clubs hold roughly 30 regattas a year.

A paved path circles the water and works well for cycling or walking, with no steep sections along most of the route. At several points there are shore access spots and rest areas where you can sit down or step closer to the water.

A methanol-powered electric ship runs on the water during summer, offering tours without diesel exhaust. The engine makes trips noticeably quieter than those of ordinary motor vessels.
