Karahnjukar dam and Halslon reservoir, a massive new controversial hydro electricity project in North East Iceland, in the wilderness area of Vatnajokull, created by damming the Jokuls a Dal river. Controversial as it flooded a huge area of one of Europe's last wilderness areas, that was home to nesting Whooper Swans and Pink Footed Geese. The project does however produce 40% of Iceland's electricity from renewables. The projects statistics are as follows, power generation, 700MW, gross head, 600 metres, Max flow 144 M sec, Halslon Lake area 57KM squared, storage volume 2.1 million metres, dam height 198m (the tallest in Europe) headrace tunnels 73km. 100 % of Iceland's electricity is generated from renewables, 70% from hydro and 30% from geothermal. This shot shows the overflow from the dam in late summer.
