Dry polder Žichlínek

It was construct on the confluence of river Sázava and Lukovský stream. Institution in charge is Povodí Moravy and polder have been put into operation in 2008.
The tank corridor Česká Třebová - Olomouc passes through the tank. The railway embankment and dams create a barrier that divides the reservoir into two areas, the southern and the northern. However, the levels of the retention space are loosely interconnected over the railway bridge profiles.
Simultaneously with the construction of the dam, both stream were revitalized. Along with the formation of meandres, wetlands and permanent bodies of water were formed at the bottom of the polder. Whole polder area has landscaping and ecological importance.
What is dry polder good for?
It is water work which is more often dry and without water. The polder is filled with water only when it is horrible that the watercourse spills from the banks. The spout is usually set that the water works leaves the so-called harmless flow. This polder is made for “twenty year water”. But if the capacity of the polder is full, the water will overflow with so-called safety spillway. If there will be more water, the worst scenario it can delay the flood.
