The lake stretches about 41 kilometers (25 mi) north from the village of Krøderen in Krødsherad on its southern end and reaches north to the village of Gulsvik in Flåmunicipality in the valley of Hallingdal. The lake has a surface area of about 44 km2; and a maximum depth of 130 m (430 ft). The primary river flowing into it is Hallingdalselva to the north. Its outlet is via the Snarumselva at the south end of the lake. Snarumselva flows into the Drammen River by Geithus in Modum.[citation needed]
At Noresund, along Norwegian National Road 7 (Rv7), there is a bridge over the lake. Krøderen is only about 200 meters (660 ft) wide at a point.
Sole Hotel (Sole Hotell Krødsherad) is located along the national road between Krøderfjorden and Norefjell. Sole Hotel was originally a former doctor's home dating back to the beginning of the 1900s. In 1966, the facility opened as Norway's first conference hotel.[2]
Etymology
The Old Norse form of the name must have been *Krœðir. This name is probably derived from the verb kryda 'stream/press together' related to Old Englishcrudan 'to press, push'. In that case the name is probably referring to the narrow strait of Noresund.[citation needed]
