The dam, also referred to as Tesnovska or Bila Tremesna dam, lies on the River Labe, 4 km upstream from Dvur Kralove nad Labem, in a narrow valley which cuts through Koclerovsky ridge. Since 1964 the dam has had a special conservation status as a national technical monument and is a very popular tourist destination. The decision to build the dam was adopted in 1897 after a flood which devastated the entire Labe valley down to the town of Pardubice. The dam was built in 1910-1920, with works being interrupted by World War One. After completion, it was the greatest reservoir in the Czechoslovak Republic. It is an arc-shaped brick gravity dam made from local sandstone bricks, with the dam foundation 37 m broad and 7.2 m crest breadth. The crest length is 218 m and the crest elevation is 41.4 m above the footing bottom. The reservoir is 5.1 km long with the designed storage volume, and the maximum backwater zone is 85 hectares (58.6 hectares under ordinary conditions). A power plant with an output of 2x 600 kW was installed in the dam in 1923. The dam was built after a project in the Neo-Gothic style, with the crest embellished with two gates with decorative turrets. The dam master’s house resembles a small stone castle with a dominating tower and battlement.
