The lake Eikern stretches almost 20 kilometres, from Vestfossen in Øvre Eiker to Eidsfoss in the municipality Hof. Eikern is known as one of the least contaminated lakes in the south east of Norway, where raw water can be used untreated as drinking water for the citizens in Øvre Eiker. The lake's maximum depth is measured at 156 metres, whereas intake of the raw water is at 45 meters. I am so lucky to have a good friend who's family own a holiday home along the very steep shore of the lake. This weekend we are a group of friends who are going there for food, drinks and fun, swimming, water ski competitions and sun!
