This is a video from Haldenvassdraget, or the Halden watercourse. It lies along the border with Sweden and consists of a number of lakes, rivers and canals.
Haldenvassdraget 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. This video from Haldenvassdraget 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). It also includes scenes from the summer opening of the locks in Ørje in 2019.
In addition to this video from the Halden watercourse, you may read two articles in Norwegian on Sandalsand Norge:
Haldenvassdragets kanalmuseum: The Halden Canal is the oldest of Norway’s two canals. It dates back to the period 1852-1860 and was largely in operation until 1982. In Ørje we find the Haldenvassdragets canal museum with a very informative indoor exhibition, and an outdoor area that is at least as interesting.
Haldenvassdraget fra nord til sør tells about the road trip along this watercourse. Along the border with Sweden in south-eastern Norway, there are a number of natural lakes and rivers. In the middle of the 19th century, they built a continuous waterway to transport timber to the factory facilities in Halden. We call it the Haldenvassdraget.
