Regional water situation

Southern and Southwest Finland 2.6.

The water levels of rivers on the southern and southwest coasts are mainly lower than usual at the beginning of June. Precipitation levels of the first half of the year have, in many places, remained the lowest during the observation period, and there are only scattered showers forecast for the following week. However, if the highest precipitation level forecasts for the end of the week are realised, the water levels of small rivers may rise as rainfall hits the area.

The water levels in the regulated lakes of Southern and Southwest Finland are mainly at their usual levels. The water level of Lake Pyhäjärvi, in Säkylä, has remained at a typical level, as flow regulation has been kept low since the beginning of the year, first due to the low-snow winter and then the preparation for drought. Lakes Lohjanjärvi and Hiidenvesi have also remained relatively close to the typical level at the beginning of June. The water level of the natural lake Pyhäjärvi, in Artjärvi, is currently at the lowest level in the measurement history and, according to forecasts, continues to decline.
