On the railway embankment running along the western part of the lake, there is a footpath. In warm weather, the inland waters quickly begin to bloom, which is a result of the high nutrient input from the freshwater inflows and the municipal sewage treatment plant. On the eastern shore, hidden by a school forest, lies the former municipal landfill. This becomes visible again and again at the eroding shoreline. This landfill is monitored with the help of control drillings.
