The long chain of narrow lakes and rivers called Upperudsälven are a main part of the Dalsland Canal, a 150-year-old and 150-mile-long waterway through the province of Dalsland, from Lake Vänern all the way to Norway. Upperudsälven was important to the people of Dalsland long before the canal was completed, both for energy and transportation, but it was impossible to sail all the way from end to end, because the lakes and rivers were interrupted by rapids and cataracts. The canal was built to solve this problem. Today Dalslands Canal is mostly frequented by tourists in private boats or tour boats. The ride will take you through 31 locks and the aqcueduct of Håverud where construction of a lock was impossible. Instead the aqueduct takes the boats across the Håverudsfallet waterfall in a what can best be described as a steel bath tub.
