The Halden watercourse lies along the border with Sweden and consists of a number of lakes, rivers and canals. It was developed in the middle of the 19th century to transport timber to the factory facilities in Halden, on the coast.
The total length is about 150 km. The film shows a couple of locks in the Soot Canal, and the three remaining and fully operational locks along the Halden Canal (Ørje, Strømsfoss and Brekke). The film also includes scenes from the summer opening of the locks in Ørje in 2019.
