About Nysa Dam

The Nysa reservoir on the Nysa Kłodzka river in Lower Silesia holds 121.7 million cubic metres and forms the downstream partner to the older Otmuchów reservoir immediately upstream. Completed in 1971, the 36-metre concrete gravity dam near the town of Nysa in Opolskie province serves primarily for flood control, water supply to the Opole and Nysa urban areas, and recreational provision. The two-reservoir system on the Nysa Kłodzka provides coordinated flood retention capacity for the Sudeten Foreland, a region historically subject to flash flooding from the steep Sudeten Mountain catchments following heavy rainfall or rapid snowmelt. The Nysa reservoir's warm, moderately eutrophic waters make it a popular recreation spot: the Nysa camping and beach complex on the western shore is one of the largest and best-developed in Lower Silesia, attracting visitors from the Wrocław conurbation 80 kilometres to the north. Windsurfing, sailing, motorboat racing, and freshwater angling are all practised on the reservoir. Ecological surveys document populations of great cormorant, night heron, and various migratory waterfowl using the reservoir during spring and autumn passage. The surrounding Sudeten Foreland agricultural landscape is known for its traditional Silesian village architecture and orchards of Silesian prune plum.
