The lake was created as a strategic measure to regulate the flow of the Nysa Kłodzka River and mitigate historical flood risks in the Opole Voivodeship.
It is commonly referred to by locals as Głębinowskie Lake, named after the village of Głębinów located on its shores.
The reservoir's dam structure includes an integrated hydroelectric power plant that contributes to the local energy grid.
The lake area provides a stopover point for migratory bird species, making it a recognized site for amateur ornithology.
Its construction necessitated the relocation of several historical buildings and infrastructure from the original river valley.
The lake depth varies significantly based on water management requirements, often reaching over 20 meters near the dam wall.
Nyskie Lake is a large reservoir formed by damming the Nysa Kłodzka River, acting as a primary flood control mechanism for the surrounding region. The lake covers approximately 2,000 hectares and features a dam structure completed in 1971. It serves as a regional hub for water sports including sailing, windsurfing, and recreational fishing. The shoreline incorporates several designated beaches and marinas, particularly concentrated near the northern and eastern banks. The reservoir is surrounded by the Opawskie Mountains, providing a distinct geographic backdrop. Water quality is monitored regularly during the summer season to ensure suitability for swimming. Several islands are scattered throughout the reservoir, some of which are protected habitats for local waterfowl. The site is part of the larger Nysa Reservoir system, which integrates with the nearby Otmuchowskie Lake.

Check the local municipal water quality reports online before planning a swimming excursion.
Bring windproof gear if planning to stay on the northern shoreline, as the area is prone to steady crosswinds.
Utilize the designated marinas for boat launching rather than attempting to launch from wild shoreline areas.
Attempting to swim near the dam infrastructure or spillways, as these areas have strong, hazardous currents.
Water sports infrastructure and lifeguarded beach zones are generally restricted to the summer season.
Observe designated swimming zones and refrain from operating motorized watercraft in marked wildlife protection areas.
