Natural Lakes and Ponds

Natural lakes are relatively rare in the Czech Republic due to its geological history and climate. However, there are several noteworthy natural water bodies that contribute to biodiversity and provide important ecological niches.

Černé and Čertovo Lakes

Located in the Krkonoše Mountains, the Černé (Black) and Čertovo (Devil’s) lakes are among the few natural glacial lakes in the country. These lakes were formed during the last Ice Age and are situated at high altitudes, creating unique alpine ecosystems. The Černé Lake is the larger of the two, covering approximately 4.7 hectares, and is known for its deep, clear waters. These lakes are protected as part of the Krkonoše National Park and attract nature enthusiasts and researchers studying alpine flora and fauna.

Rožmberk Pond

Although technically a pond, Rožmberk is the largest fishpond in the Czech Republic and one of the largest in Europe, covering about 489 hectares. Located in the South Bohemian fishpond system, it was constructed in the late 16th century for fish farming, mainly carp. This pond plays an essential role in traditional Czech aquaculture and is surrounded by wetlands that support diverse bird populations, making it an important site for ornithologists and bird watchers.

Other Natural Ponds and Small Lakes

The Czech landscape is dotted with thousands of smaller ponds, many of which were historically created for fish farming and irrigation. These ponds, often centuries old, form a characteristic part of the rural environment and contribute to maintaining local biodiversity. Many are part of protected landscape areas and serve as breeding grounds for amphibians, insects, and waterfowl.

Major Rivers and Their Importance

While lakes and reservoirs are vital, the Czech Republic’s rivers form the backbone of its hydrological network. They have shaped the country’s geography and have been central to its history, economy, and culture.
