About Aker River

Akerselva, also known as Akerselven or the Aker River, is a significant waterway flowing through Oslo, Norway. Originating from Maridalsvannet in Oslomarka, it winds through various boroughs including Nordre Aker, Sagene, Grünerløkka, central Oslo, and Grønland, before culminating at Paulsenkaien and Oset in Bjørvika.

The river spans approximately 8.2 kilometers (5.1 miles) and features a notable elevation drop of 149 meters (489 feet) from source to mouth.

Historically, Akerselva played a crucial role in Oslo's industrial development, with many old industrial buildings still lining its banks. However, by the 1970s, the river suffered severe contamination due to industrial and sewage discharges.

A significant turnaround occurred in the 1980s, with concerted efforts to reduce emissions and rejuvenate the river's ecosystem. Today, Akerselva stands as "Oslo’s green lung," boasting park areas along its entire stretch and supporting salmon spawning in its upper parts.
