Regional water situation

Kanta-Häme, Pirkanmaa and Pori region 18.3.

In the Kokemäenjoki river basin, the water levels of rivers are at normal levels for the season, but may rise slightly when the remaining snow melts with this week’s milder weather. However, the rise in water levels will remain minor, as no heavy rainfall is forecast for this week.

The flow regulation of large regulated lakes in the river basin has been regulated during the winter, following the water and ice situation downstream. When conditions allowed, room has been made in the lakes so that flow regulation can be restricted, if necessary, during winter frost periods, floods in Loimijoki or spring floods. Spring declines in lakes have been carried out moderately this year, as there is clearly less snow than average.

The water levels of other lakes are higher than average in many places. The water levels of Keurusselkä, Äväntäjärvi, Längelmävesi and Pihlajavesi are 15-35 cm above the median level and partly already on a spring rise. The spring flood peaks in lakes are forecast to be mainly smaller this year than last year.

In the Karvianjoki river basin, the water levels of lakes and rivers are mainly higher than average and will remain close to their current levels in the next few days.
