The Marienbad dam ( Vodní nádrž Mariánské Lázně in Czech ) is a drinking water dam on the Úšovický potok in the Czech Republic . It is located two and a half kilometers north of Marienbad / Mariánské Lázně in the Imperial Forest / Slavkovský les. The reservoir is located in the first zone of the drinking water protection area and is not accessible.
geography
The dam, surrounded by extensive forests, is located in Maxova údolí ( Maxthal ). The road from Marienbad to Prameny runs west of the reservoir . Surrounding places are Nimrod in the north, Rájovská Myslivna and Rájov in the east, Na Polomu and Zádub-Závišín in the southeast, Marienbad in the south, Lunapark in the southwest, Lázně Kynžvart in the west and Králův Kámen and Kladská in the northwest.
history
The construction of a dam in Maxthal above the city goes back to a proposal by the Marienbad City Council Wenzel Lerchl in 1883. The following year, the Prague hydraulic engineer Andreas Rudolf Harlacher (1842–1890) presented a project that envisaged a 150 m long and 16.5 m high gravity dam based on the Intze principle . In 1887, the Marienbad master builder Friedrich Zickler (1829–1899) created another project for a dam with a 20 m high embankment dam with a width of 9.55 m at the base and 3.65 m at the top.
After the flood of November 1890, when the dam of the Podhorne Pond broke and the city of Teplá was flooded, the city of Marienbad postponed the dam project. From then on, the council saw the earthfill dam proposed by Zickler as a danger to the city. The prolonged drought in 1892 prompted the Marienbad Council to decide to build a dam. Between 1894 and 1896, the project of the late Professor Harlacher was realized for 160,000 guilders by the building company Karl Kreß from Prague. The dam served as a drinking water reservoir for the spa town of Marienbad, and it also protected the lower Maxthal up to the Lunapark from flooding. The dam construction was the first in Bohemia and one of the first in the Austro-Hungarian monarchy with a dam.
Since the capacity of 92,000 m³ of water proved to be insufficient in dry periods, the storage space was initially increased in the years 1901–1902 by removing soil. Due to the still inadequate amount of water, the dam wall was raised by three meters to its current height in 1912 and reinforced on both sides up to the crown with embankments.
A project for further enlargement that began in the 1920s was never carried out. In 1955 a water supply was built from the Podhora dam .
description
The 15.58 m high gravity dam has a length of 116 m and is 3.5 m wide. With the embankments on both sides, the dam width is 19.5 m.
The dam is part of the Podhora-Mariánské Lázně water management system. In dry periods, water is supplied from the Podhora and Mnichov dams.
