Other Site Characteristics

An approximately 50 km long river branch, closed with locks at both ends . Its most precious assets are the floating mats of Sphagnum sp. that have developed since the 1920s. For the upper stretch, which is degraded to a large extent, a significant mud deposit is characteristic. In the middle stream, nice floating mats of Sphagnum sp., in the lower stretch open water surface are present. The region is full of holiday resorts that pose a heavy load to the site.
