Completion of the work already under construction Krounk, Kutřín, construction of the polder. The work consists in building a dry retention reservoir (polder) of Kutřín. The construction of the dam body is designed as a concrete gravity dam. The total length of the dam is approx. 146 m (including the spillway of the safety overflow), the maximum height of the dam above the ground is 17.80 m, the total width of the crown of the dam is 5.67 m. Part of the body of the dam is a functional object with two lower outlets and a migration passage. As a safety object, a lateral safety spillway with a length of 25 m of the spillway edge is proposed, located at the right-bank tie-off of the dam with a subsequent slip from the spillway, which ends with a weir. The safety spillway is designed to safely transfer a Q10000 control flood (106 m3/s).
