Vodní nádrž Mlýnice, reservoir in Nová Ves, Czech Republic

Vodní nádrž Mlýnice is a reservoir near Nová Ves that covers roughly 5.2 hectares and reaches a maximum depth of 14 meters. The dam is built from stone and concrete with manually or automatically operated gates and spillways to control water flow.

The reservoir was built between 1904 and 1906 on the Albrechtický stream as part of a plan to construct two dams in the Lužická Nisa basin for the Liberec water cooperative. After a major flood in August 2010 that sent water over the dam and washed away soil beneath the structure, reinforcement repairs were carried out from 2011 to 2012.

The reservoir is named after the Mlýnice settlement and its mill in Nová Ves, first dammed here on the Albrechtický potok in 1904–06. Angling is the main use today; swimming is not expressly forbidden but the water stays cold even in hot summers because of the shaded, forested valley, so it draws fewer bathers than the nearby Fojtka reservoir.

The reservoir is easily reached by small country roads from nearby villages and typically has no entrance fee, making access free for anyone. Small parking areas and paths allow visitors to get close to the water while respecting the quiet nature of the place.

The dam is an Intze-type gravity wall of hornblende granite rubble masonry set in cement-trass mortar, built under the supervision of Prof. Intze of Aachen; after his death in December 1904, senior engineer E. v. Scheure took over, with H. Schmidt directing works on site.
