Bedřichov Reservoir, reservoir in Bedřichov, Czech Republic

Bedřichov Reservoir is a large body of water in the village of Bedřichov, nestled in the Jizerské hory mountains. The water reflects the surrounding greenery and sky, and stretches across a forested valley where birds and wildlife move freely through the landscape.

After floods in July 1897, the Wassergenossenschaft association had Otto Intze of Aachen design a dam on the Schwarze Neiße (Černá Nisa). Work ran from November 1902 to December 1905, with E. von Scheure taking over after Intze's death in 1904; the dam held two floods already in March 1906.

The reservoir's German name, Friedrichswalder Talsperre, refers to the village of Friedrichswald, today Bedřichov. The dam was built by the Wassergenossenschaft, a water cooperative founded in 1900 by local industrialists after the floods of 1897. Its masonry used granite from the nearby Friedrichswald quarry, and cement came from Čížkovice.

The dam crown sits at 775.26 m above sea level; the 340 m long, 23.5 m high wall is reached on foot from Bedřichov. The reservoir lies on the Černá Nisa, the upper course of the Lužická Nisa, and the water also feeds three small hydroelectric plants, so banks and outflow areas are working infrastructure rather than a park.

The dam is founded on a 2-metre-high concrete slab, and its granite blocks came from the nearby Friedrichswald quarry. The reservoir holds 2.0 million m³ of water and already held back two floods in March 1906, before construction was fully finished.
