About Võrtsjärv

Võrtsjärv is a large, shallow freshwater lake in southern Estonia and is the country’s second-largest lake by surface area, roughly 270 square kilometres. It is ecologically important for waterfowl and reedbed habitats.

The lake supports extensive reedbeds, mudflats and shallow open water that attract large numbers of migratory and breeding birds. Its outflow is the Emajõgi river, which connects Võrtsjärv eastwards to Lake Peipus and forms a key part of the regional drainage network.

Historically the lake has been used for local fisheries and traditional reed harvesting; scientific interest in Võrtsjärv focuses on its limnology and the dynamics of shallow lake ecosystems. Human use and conservation efforts focus on balancing fisheries, habitat protection and tourism.

Võrtsjärv lies in south-central Estonia amid low, agricultural countryside and wetlands. The lake is accessible by regional roads and is a regional focal point for birdwatching and freshwater research.

  • Hydrology: The lake feeds the Emajõgi river, which flows eastwards toward Lake Peipus and is an important part of Estonia’s inland water network.
  • Depth and habitat: Very shallow compared with its surface area, with an average depth around 2 metres and a maximum depth of only a few metres, creating extensive reedbeds and wetlands.
