is one of Bornholmâs most water-rich streams. Several watermills have been located along the stream, which runs inland through the island. At SlusegĂ„rd, for several hundred years, a watermill has stood. The current one dates back to around 1800, at which time there were about 90 watermills on Bornholm. Here, the power of the water has also been used in a trout farm going far back in time. The facility with the trout house, icehouse, and smokehouse was first established in 1880." - Translated from Danish.
