Water situation 14.7.

Large natural lakes remain exceptionally low

The rainfall last weekend dramatically raised the water levels of smaller rivers in the southern coast. For the most part, rivers have fallen close to the average seasonal levels, but for example Uskelanjoki river is still high. Rainfall caused damage to roads at least in Somero, where roads have collapsed due to flooding, and many roads are still closed to traffic. According to forecasts, the current week will be low in precipitation until the weekend.

Despite last week’s rainy weather, the water levels of many natural lakes are still exceptionally low in the area extending from Eastern Finland to Pirkanmaa. Of the large lakes, for example, the water levels of Lakes Kallavesi, Keitele and Iso-Tarjannevesi are exceptionally low for the season. The water levels of Lake Saimaa and Lake Päijänne are still around 40 cm lower than on average this time of the year. According to the forecast, the water levels of large lakes will decline slowly in July.
