Regional water situation

Kanta-Häme, Pirkanmaa and Pori region 21.4.

In the Kokemäenjoki river basin, the water levels of rivers are low. During the weekend, any rainfall in the area may cause the water levels in rivers to rise.

The water levels of large regulated lakes in the Kokemäenjoki river basin are mainly higher than average, due to the early spring and the fact that due to the low amount of snow, there was no need to lower the water levels of lakes to very low levels. The water levels of natural lakes will remain clearly lower than usual for the summer, as the spring inflows will remain low. In Valkeakoski, restrictions on flow regulation were introduced at the end of March, to prevent excessive decline of the Mallasvesi water level.

In the Karvianjoki river basin, river and lake water levels are lower than average, as the water levels usually rise during April. This week, the water levels will mainly remain unchanged or declining slowly.
