Maridalsvannet
Maridalsvannet () is a lake in Maridalen, Oslo, Norway. It is the largest lake in the municipality of Oslo, serving as its primary drinking water supply. The lake drains via the river Akerselva to the Oslofjord. The primary inflows are Skjærsjøelva and Dausjøelva. The Hammeren Hydroelectric Power Station exploits the fall from Skjærsjøen to Maridalsvannet. The shores of the lake and substantial areas of woods and fields around it are owned by the city of Oslo to protect the water supply. Some farms are still operated under city supervision, but others were closed down in the mid-20th century; their remains are marked by historical signs. Hiking, cycling, and cross-country ski trails run near the south side of the lake and connect to the system of trails in the forests that surround Oslo. They can be reached by a short walk from the Kjelsås trolley, bus, or train stations. Trails run alongside Akerselva from the Marridalsvannet dam to near the Oslofjord. The Gjøvik Lin ...

Maridalen
Maridalen is a valley in the north of Oslo, Norway, just above the suburb of Kjelsås. Considering that Maridalen is within the Oslo city limits, this area has a very low population density. The valley consists of forests, lakes and agricultural land. Most of the valley is made up of the lake Maridalsvannet, which serves as the primary source of drinking water for 90% of Oslo's population. The only hydroelectric powerplant within the City of Oslo, Hammeren Hydroelectric Power Station is located at Brekke in Maridalen. The valley is a popular recreational area featuring many hiking trails, cycling tracks for summer usage, and groomed cross-country trails in winter. Both the lake and valley are protected by the community. Maridalen Church and the church ruins of the ancient St. Margaret's Church are located north of Maridalsvannet. A bus route runs along Maridalen, starting at Nydalen Subway Station. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
