Site description The pond was established in 1524 in a shallow valley of the Otava river. It is the largest pond of the Písek administrative region (104.5 ha) and it is situated about 10 km southwest of the city of Písek. It is a comparatively shallow fish-farming pond with a depth of about 1 m and extensive reedbeds and sedge stands. It is surrounded by an extensively managed agricultural landscape. East of the pond, behind an wind-deposited sand dam, there are pools (6.2 ha), which is what remained after the extraction of stucco-type sands in the area. Percolating water from the pond has created a unique mosaic of various environments in the pools.

Key Biodiversity The IBA is important for both breeding and passage waterbirds.
