A pond designed for Q100 has withstood a 100-year flood during extreme rainfalls in Czechia in September 2024.
The pond has a flow-through design with a littoral zone at the beginning for amphibian breeding and water purification. The outlet of the pool is designed as a free overflow and is made by a paved stone chute set in cement mortar. The capacity of the spillway is designed for Q100. During the extreme floods in September of 2024, it proved its functionality by draining all the rainfall.
The pier and dam remained undamaged after the water level dropped.
