Stadil Fjord is (despite its name a fjord) a freshwater lake of about 1730 hectares, located about 5 km northwest of Ringkøbing and about 2 km from the North Sea beach in Jutland, Denmark. The lake is a shallow lake with a maximum depth of just 2.5 metres. In the south-eastern part lies the approximately 100 ha large, publicly accessible island of Hindø, which is connected to the mainland by a small bridge. Stadil Fjord, Ringkøbing Fjord and Vest Stadil Fjord were originally one large continuous area, but after drainage measures the connection between the fjords is reduced to a narrow channel from Vest Stadil Fjord to Stadil Fjord and the Vonå outflow, which flows into Ringkøbing Fjord. Stadil Fjord also receives the waters of the rivers Madum Å, Tim Å, Sund Å and Hover Å and some smaller streams. In the early 1990s, the lake was polluted with large amounts of nitrogen and phosphorus, resulting in poor water quality[2]. However, the lake could be saved and is now one of the cleanest lakes in Denmark. Source Wikipedia
