The water levels of rivers in Northern Finland have not changed much from the previous week’s levels, and at the moment, they are mainly close to the average level of the season. The snow water equivalent around the rivers in Lapland is mainly close to the average in April but is slightly higher than average in River Muonionjoki and the headwaters of River Ounasjoki.
