It was built in 1536 because mining activities required ever more water to power machinery and equipment, while timber supplies around Horn\u00ed Slavkov and Kr\u00e1sno were steadily diminishing. Wood therefore had to be transported to the mining operations from the distant Kyn\u017evart forests. The route was called Flossgraben.<\/span><\/p>\n Flossgraben represented a highly purposeful and carefully planned intervention in the natural water regime. Given the terrain, the project depended primarily on precise surveying and maintaining a minimal gradient, ensuring that water could successfully be brought to the required elevation and fulfilling the purpose of the entire undertaking. The total length of the water channel was 24.2 kilometres. Dlouh\u00e1 Stoka has been a cultural monument since 2003.<\/span><\/p>\n<\/div>
