Regional water situation

Kainuu and Oulu-Koillismaa 19.9.

In the River Oulujoki water system, water levels in lakes are no longer declining due to rainfall last week. Rainfall forecasts for the next few days may increase water levels slightly.

Water levels of regulated lakes are mainly close to their normal September levels. However, for example, the water level of Lake Kiantajärvi remains around 15 cm above the average level of the season. The water level of Lake Oulujärvi is also almost 20 cm higher than its average level in September and is declining, but the water level will remain higher than usual at least until the end of September.

The water levels of the natural lakes in the region are still higher than the normal levels of the season, and their decline has slowed down. For example, the water level of Lake Lammasjärvi in the headwaters of the Sotkamo route is about 40 cm and Lake Lentua about 25 cm higher than average. The water levels will remain high compared to average heights, during the autumn.

In the Kuusamo region, the water levels of Lake Kitkajärvi and Lake Muojärvi are close to their normal September levels. The water level of Lake Muojärvi is slightly above the average level of the season, while the water level of Lake Kitkajärvi is close to the average. Water levels are expected to rise slightly during the remainder of the month due to rainfall.
