The Kisköre Dam was built between 1967 and 1973 on the right bank of the Tisza 404 river km section in Hungary. It is now an impassable barrier for aquatic organisms, except during short and rare periods of floods. A fish-lock was constructed to provide a permeable ecological corridor, but, because it is a narrow, dark, reinforced concrete channel, it has proven over the years to be ineffective. For this reason, a new fish pass was built in 2014. It is a type of ecological corridor that is unique not just for Hungary but also for Central Europe. It consists of an artificial, winding stream in the landscape, 1371 m long, which ensures the smooth passage of aquatic beings regardless of the season, even with the highest water level difference of 10.6 m between the two sides of the Kisköre dam. This allows for a continuous ecological link between the river and the lake. The design of the facility was finalized with the cooperation of conservation professionals, fish biologists and engineers.The fish-pass establishes links between several stakeholders: conservation, water management and tourism draw attention to the need to preserve and maintain water, habitats and protected species. It connects Lake Tisza and Middle Tisza and is proof that besides a water management facility, the interests of nature protection and tourism can prevail. As a part of a Site of Community Importance (SCI) it serves as a refuge for targeted fish and bird species and in which otters and beavers find their home as well. It is an exciting place for cyclists and hikers to rest, and can also be used for rafting. It serves as a research area for ecologists, fish biologists, technical engineers. Bringing nature closer to humans, the behavior of fish in their natural habitat can be observed by a monitoring window and a live webcam.
