Vodní nádrž Pilská, Reservoir in Žďár nad Sázavou, Czech Republic

Vodní nádrž Pilská is a reservoir on the Sázava River, mostly in the north of Žďár nad Sázavou and partly in Polnička. It was built between 1959 and 1962 on the site of the former Pilský fishpond, and its homogeneous earthen dam stands on the old pond dam. The reservoir covers 75 hectares and holds almost 2 million cubic meters of water.

The reservoir was built in 1962 on the site of an older fishpond called Pilský, originally created to supply water for the growing machinery industry in the region. Over time it evolved into a recreational area while maintaining its core functions of water storage and flood protection for the city.

The area is accessible from April to October depending on weather, with two campgrounds offering facilities, plus walking and cycling paths through surrounding nature. A large car park near Hotel Tálský Mlýn makes access straightforward, and sandy beaches with grassy areas provide comfortable spots to rest.

A sandstone boundary stone with concrete statues of a lion and an eagle, unveiled on 6 November 2009, stands about 100 metres south of the actual Bohemian-Moravian line. Sculptor Michal Olšiak's group "Hraniční kámen" was placed off the true border because of property ownership.
