Record: 5.50 km
The Kimola Canal is a canal about 5.5 kilometres long in the Kymijoki River. The canal, located in the northern part of Kymenlaakso on the border between the municipality of Iitti and the city of Kouvola (before the merger of the municipalities in 2009, the municipality of Jaala), bypasses the so-called bend in the Kymijoki River and bypasses the Vuolenkoski and Mankala power plants, shortening the water journey by almost 30 kilometres.Website:https://www.kouvola.fi/kouvolankaupunki/strategia/karkihankkeet/kimolan-kanava/
