Site description A large storage reservoir on the Nysa K³odzka river, situated amongst hills in an agricultural landscape, not far from Nysa reservoir. Broadleaved forest adjoins the embanked eastern side. The western and southern shores have a more natural character, being covered with a wide belt of willow Salix bushes. The northern part is used for recreation. The reservoir controls water flow for navigation on the Odra river, and there are considerable fluctuations in water-level. Although some parts of the shore are shingle, the bottom of the reservoir is generally muddy and sandy.

Key Biodiversity More than 20,000 migrating and wintering waterbirds occur regularly, mainly geese Anser, ducks Anas, and Vanellus vanellus and other waders.
