The Mseno dam (Grünwald dam) is a typical Intze dam in the Jizera Mountains in Bohemia (Czech Republic), which was part of Austria at the time of construction. The dam is located in Mšeno nad Nisou , a district of Jablonec nad Nisou .
purpose
The dam serves to protect against flooding, the increase in low water levels and the supply of industrial water. The dammed body of water is the Grünwald water in the headwaters of the Lusatian Neisse .
The dam
The gravity dam was built from March 1906 to 1909 under the supervision of chief engineer E. v. Scheure built according to the Intze principle according to plans by Prof. Otto Intze . The local construction manager was the engineer Hermann Schmidt.
The wall is made of hornblende granite rubble. Cement trass was used as the mortar .
More dams
To protect against flooding , a total of six dams were planned in the Görlitzer Neisse ( Lausitzer Neisse ) river basin . The trigger was the floods of 1897 in large parts of Bohemia , Saxony , Prussia and the Alpine countries. For this purpose, the "water cooperative for regulating watercourses and building dams in the Görlitzer Neisse river basin" was founded in 1900. - The other five are:
- Harzdorf ( Harcov ) (storage volume 0.63 million m³)
- Friedrichswald / Schwarze Neisse ( Bedrichov dam ) (storage volume 2.0 million m³)
- Görsbach / Gierschbach (storage volume 0.5 million m³) (was still in planning in 1906)
- Voigtsbach ( Fojtka ) (storage volume 0.25 million m³)
- Mühlscheibe / Scheidebach ( Mlynice ) ( storage volume 0.25 million m³)
The Görsbach dam was probably not built. No suitable dam can be found in lists of Czech dams today.
