Bjoreio

The Bjoreio is a river in Eidfjord Municipality in Vestland, Norway. The river is 72 kilometers (45 mi) long, and it has a drainage basin of 627 square kilometers (242 sq mi). Its natural average discharge is 25.2 cubic meters per second (890 cu ft/s), but this is considerably less today because of hydroelectric infrastructure along the watercourse. The Bjoreio has its origin on the northwest side of Sildabunutane, a 1,444-meter (4, 738 ft) mountain in Hardangervidda National Park. The river, which is called the Eitro here, then runs southeast through Sildabudalen, a wide valley, and into Langavatnet, a lake at an elevation of 1,223 meters (4, 012 ft). Under the name Snero the river continues the short distance to Tinnhølen, a lake at 1,213 meters (3, 980 ft). When it flows out of Tinnhølen the river is now named Bjoreio, and it runs to the northwest out of the national park and down through the Bjorei Valley (Bjoreidalen). At the Nybu tourist lodge it is joined by the Svinto from the east. Here the river runs through the Bjorei Valley Nature Reserve (Bjoreidalen naturreservat). In the nature reserve there is a ban on walking outside specially marked trails from May 20 to July 20 to protect nesting birds. Further downstream, at Storlia, is the 81-meter (266 ft) high Sysen Dam, a large stone embankment that creates Lake Sysen on the Leiro River just before it empties into the Bjore
