Regional water situation

Southern and Southwest Finland 6.10.

The water levels in rivers on the southern coast have declined from their highest levels this year in just over a week ago. The heavy rainfall forecast for Friday will cause the rivers to rise again. If the highest rainfall forecasts are realised, the water levels in the rivers on the southern and southwest coast will rise to autumn flood levels at the weekend or next week. Water may thus flood the lowest-lying fields.

The water levels of lakes in Southern and Southwest Finland rose higher than average, after the rainfall at the end of September, and the rainfall at the end of the week may raise them further. Lakes Hiidenvesi and Lohjanjärvi are higher than average. The flow regulation of Lake Pyhäjärvi in Säkylä has been increased. The water level of the natural Lake Pyhäjärvi in Artjärvi is approximately 10 cm higher than average and rising as typical in autumn.
