Bye bye Swedish summer. Today autumn arrived so this is a celebration to the fantastic summer of 2014. The photos are from Ombo öar (Ombo islands) outside Djäknasundet on the lake Vättern's west side. Vättern is the second largest lake (by surface area) in Sweden, after Vänern and the sixth largest lake in Europe. The lake's total surface area is about 1,912 km2 (738 sq mi), with a drainage basin a little over double that, about 4,503 km2 (1,739 sq mi). The deepest known point, located to the south of the island of Visingsö, is 128 meters (420 ft). Vättern has been famous for the excellent quality of its transparent water. Many of the municipalities in the area receive their drinking water directly from Vättern. The lake water requires very little treatment before being pumped into the municipal systems and the natural, untreated water can be safely drunk from almost any point in the lake. It has been suggested that Vättern is the largest body of potable water in the world. The surrounding municipalities process 100% of their sewage to keep it that way. However, the lake is now under threat from mining companies that want to start business close to the lake, with the risk of polluting the water.
