Regional water situation

Kanta-Häme, Pirkanmaa and Pori region 2.6.

In the Kokemäenjoki river basin, the water levels in rivers are low, and no significant changes are forecast for the current week.

The water levels of large regulated lakes in the Kokemäenjoki river basin have mainly been kept higher than usual during the first half of the year, so that the water levels would be closer to normal levels during the summer. At the moment, the water levels are mainly close to the average levels, but similarly, the outflows of lakes are small.

The water levels of natural lakes will remain clearly lower than usual during the summer, as the spring inflows remained small and the precipitation levels remained low. The water levels of lakes are at the lowest seasonal levels of the measurement history, in places. Lakes Liesjärvi and Kitusjärvi have not been this low in early-June during their entire observation history. 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 close to or below average levels, and they will remain at the current levels or decline slowly this week.
