The Pirk dam is a dam in the Free State of Saxony , which was built in 1935–1938 (the dam itself from 1937) near Oelsnitz / Vogtl. was built. The inauguration was in 1939. The dam is used for the supply of industrial water , for raising the low water level, for generating energy , for flood protection , for fishing and for recreation. The dammed body of water is the White Elster . The dam is located directly on the federal motorway 72 near the Pirk junction.
The barrier structure of the Pirk dam is a slightly curved concrete gravity dam with natural stone facing . The dam has a flooded pre- dam (Dobeck) and three fore basins. The water in the pre-dam was drained from 2007 to 2009 in order to remove washed-in sediments from the reservoir of the pre-dam and thus improve the water quality. As a compensatory measure for the construction of the nearby bypass road of the B92, a bird island was also raised.
Swimming, sailing, surfing and boating are possible in the reservoir. The operation of sports boats with internal combustion engines is expressly prohibited. At the lake there is a youth hostel , a local recreation center with a campsite , a sailing club and children's playgrounds. The Pirk dam is the largest local recreation area in Oelsnitz / Vogtl.
In the course of the flooding in Central Europe in May / June 2013 , the dam overflowed on June 2nd, and also on May 24th, 2018, when 150 mm of rain fell within one day in Vogtland.
