This article presents the subsequent stages of Lake Długie recultivation. The lake has been completely degraded and has reached a saprotrophic state due to the discharge of domestic wastewater from the neighbouring living estate. The lake’s recultivation was initiated by cutting off the domestic wastewater inflow to the lake, and followed by the reduction of storm water inflow and artificial aeration...

The obtained results have confirmed a positive role of many years’ artificial aeration in reducing the internal...
