Regional water situation

Ostrobothnia 18.2.

The water levels and discharges of rivers in Ostrobothnia are close to the average levels of the season. At the end of the week, the weather will warm up significantly throughout the country, which will cause river water levels to rise also in the Ostrobothnia region. In particular, the water levels of small rivers may rise significantly. Rainfall has also been forecast in the Southern Ostrobothnia area at the end of the week, which contributes to increasing water levels.

The water levels in the lakes in the region are still higher than usual but declining slightly. Lake Lappajärvi is 30 cm and Lake Pyhäjärvi is 20 cm above the average seasonal level.

In Iijoki, the water levels and discharges are at typical seasonal levels. Also there, the warmer weather at the end of the week will increase runoffs and raise water levels in rivers and lakes, although the rise will be smaller than in Ostrobothnia. Flow regulations of Lake Kostonjärvi and Lake Irnijärvi are approximately 24–25 m3/s for the time being.

There is less snow in the Ostrobothnia and Iijoki regions than average.
