“Every day at three o’clock in the summer months, the floodgates open and 300,000 litres of water per second is released. It’s quite spectacular – you just don’t understand how much water that is until you experience it,” says Maria Engström-Weber, CEO of Visit Trollhättan Vänersborg. “People come here to experience this alone.” The CEO also recalls, with fascination, the moment last summer when an old East India ship turned up to go through the sluice in Trollhättan. “It took some serious measuring to get this old, classic ship up the sluice,” Engström-Weber says.
