Tůň u Hrobic

Tůň u Hrobic is a small but ecologically valuable nature reserve on the right bank of the Elbe River, roughly one kilometer northeast of the village of Hrobice in the Pardubice district of the Czech Republic. Covering just 2.59 hectares, the site was declared a protected natural monument in May 1982. Despite its modest size, it draws nature enthusiasts looking for a quiet spot away from the region's main tourist trails.

What is this "tůň" and how did it form?

At the heart of the protected area lies an oxbow lake — a former arm of the Elbe cut off from the main river channel, which formed around 1910 as a result of river regulation works. Hydro-engineering interventions carried out at the turn of the 20th century reshaped the Elbe's course along this stretch, leaving behind a water-filled meander in the landscape. Over time, oxbow lakes like this one, cut off from a direct current, tend to silt up and become overgrown, creating a distinctive transitional habitat between standing water and wetland.

Why is the site protected?

Elbe oxbow lakes rank among the most valuable, yet also most threatened, habitats in the lowland stretches of Czech rivers. Tůň u Hrobic provides refuge for species tied to calm, still water — from amphibians to aquatic and reed-bed plants. Over the decades, natural silting and eutrophication gradually degraded conditions for the very species the reserve was meant to protect, prompting site managers in recent years to carry out a major restoration effort.

What did the restoration involve?

The state enterprise Povodí Labe carried out a comprehensive restoration of the oxbow, finishing two months ahead of schedule. The work included removing roughly 17,500 cubic meters of accumulated bottom sediment, reshaping the shoreline, and creating a littoral zone along with a separate rescue pond designed specifically for amphibians. The goal was to restore conditions favorable to aquatic vegetation and to bring back species that had previously disappeared from the site.

What can be seen there today?

Even while restoration work was still underway, rare and protected plant and animal species began returning to the renewed habitat. The desilted, reshaped banks of the oxbow created favorable breeding conditions for amphibians, including the tree frog (puštička pouzdernatá), as well as for vegetation typical of still waters and wetlands. The site illustrates how a relatively modest intervention can reverse years of habitat decline.

Frequently asked questions

Where exactly is Tůň u Hrobic located? The reserve sits on the right bank of the Elbe, about 1 km northeast of the village of Hrobice, in the Pardubice district of the Czech Republic.

When did this oxbow lake form? The cut-off river arm formed around 1910, as a result of Elbe river regulation works.

Since when has the area been protected? It was granted natural monument status on May 12, 1982.

Is the site open to visitors? As a protected area, it calls for respecting conservation rules — it's best observed from designated paths without entering the water or shoreline zone directly, especially during amphibian breeding season.

How does this place differ from typical regional attractions? This isn't a historical monument or building — its value lies in biodiversity and ongoing ecological processes rather than architecture or settlement history.
