Regional water situation

Southern and Southwest Finland 9.6.

Rainfall at the beginning of June has hardly raised the water levels of rivers on the southern and southwest coasts, but has filled the soil moisture deficit. In the next few days, any heavier rainfall may already be visible at least in the water levels of small rivers, even though the soil is still quite dry.

The water levels in the regulated lakes of Southern and Southwest Finland are still mainly at their usual levels. The water level of Lake Pyhäjärvi, in Säkylä, has remained at a typical level, as flow regulation is still low. Lakes Lohjanjärvi and Hiidenvesi have also remained relatively close to the typical seasonal level. The water level of the natural lake Pyhäjärvi, in Artjärvi, is currently at the lowest level in the measurement history, but rainfall has slowed down its decline.
