The earthen dam was built on the lower reach of the Úhlava river in 1965-1969. The reservoir has a surface of 148 hectares and a stable volume of a million cubic metres  of water. The stone dam is 36 meters high and the length in the corona is 337 m. It serves as a reservoir of drinking water, which is why the motion in its vicinity is limited. Unfortunately, a part of a village also disappeared under the water due to the dam construction.
