Water
The Kružberk Dam, located on the Moravice River, was the first valley dam built in the Odra basin between 1948 and 1955. Initially intended for energy production, its primary purpose shifted to providing drinking water for Ostrava and now serves as a crucial component of a cascade system with Slezská Harta, ensuring water supply, flow regulation, and significant flood protection.
