The Tambach-Dietharz dam is a small dam in Thuringia that was built to improve the drinking water supply in Gotha . The dam is therefore also known as the “Gotha Dam” or “Stauweiher”. It is located on the southern edge of the city of Tambach-Dietharz and dams the water of the apple city and the mean water .
Planning and construction
The civil engineer Otto Intze , who then and still is probably the most famous dam designer, was involved in the planning as an expert. However, the dam does not comply with the Intze principle in all points . The construction work began in September 1902 after 11 years of planning and preparation under the direction of the Gotha engineer Hugo Mairich , the construction management was taken over by Ministerialrat Fecht from Strasbourg. The construction company Windschild & Langelott was able to finish construction work on the dam in October 1905. After the necessary structural inspections, the dam was dammed for the first time in spring 1906.
Dam wall
The dam is a curved gravity dam made of porphyry - rubble masonry . The dam was reconstructed from 1987 to 1991, it was given a concrete shell with a width of 2.50 m at the top and 6.20 m at the bottom with an inspection passage and was dammed again on July 16, 1991.
The dam has a pre- dam in the Apfelstädtgrund.
