Vodárenská nádrž

Vodárenská nádrž is a reservoir on the edge of Ostrožská Nová Ves, a village in the Uherské Hradiště district of the Zlín Region in eastern Czech Republic. It belongs to a group of four lakes known locally as the Ostrožská jezera, jokingly nicknamed the "Moravian Sea" (Slovácké moře) by locals. Vodárenská nádrž is the second largest of the four – the largest is the neighboring Těžební jezero, formed in a former gravel pit, while the group is completed by the smaller Kunovská tabule and the smallest of the four, a natural bathing spot called Albatros.

Where exactly is the reservoir located?

Vodárenská nádrž lies within the municipality of Ostrožská Nová Ves, directly alongside the other former quarry lakes that make up the group. Its geographic coordinates are approximately 49.019°N, 17.415°E. The whole cluster of lakes sits right next to the village, making it an easy reference point for anyone exploring the surrounding countryside.

How did this reservoir come to be?

Like the other lakes in the area, Vodárenská nádrž is not a natural feature. It was created in a former gravel and sand quarry, mined since the 1950s, which was later flooded with water. The same process produced the neighboring Těžební jezero, Kunovská tabule, and Albatros. Today the whole group ranks among the largest water surfaces in the Uherské Hradiště district.

What is the reservoir used for?

The name of the lake, which translates roughly as "waterworks reservoir," points directly to its main purpose: it serves as a source of drinking water for the local water supply system. This sets it apart from the other lakes in the group, which are used mainly for recreation. Because of this function, swimming is prohibited at Vodárenská nádrž. Of the four lakes, only the smallest, Albatros, is designated for swimming.

What does the lake bed look like?

The bottom of Vodárenská nádrž is uneven and, in places, densely covered with aquatic vegetation. The reservoir also contains sandy shallows and underwater islands, meaning that depth and underwater terrain vary considerably even across a relatively small area.

What should visitors know before coming here?

Because of its role as a drinking water source, access to the shoreline and activities on the water are more restricted here than at the neighboring recreational lakes. Even so, the reservoir remains a point of interest for anyone curious about the local waterways and the landscape left behind by decades of gravel extraction, which today forms a distinctive mosaic of lakes around Ostrožská Nová Ves. The surrounding area stays quiet and green, making it pleasant for a walk along the shoreline of the neighboring lakes.
