Regional water situation

Eastern and Southeast Finland 24.4.

The warm weather in mid-April melted most of the snow earlier than usual from the Vuoksi river basin. The spring flood peaks in rivers remained smaller than normal due to the low amount of snow. The water levels of large lakes are forecast to remain lower than usual in early summer because there was little snow in the winter, and it melted early.

The water level of Lake Pielinen has started to rise. The water level is forecast to rise by 15–50 cm by the end of May depending on the amount of precipitation in the spring. Without heavy rainfall, the water level is predicted to remain significantly lower than usual in early summer.

The water level of Lake Kallavesi is around 30 cm higher than the average level of the season due to the early melting of snow. The water level is forecast to start declining earlier than usual, already at the beginning of May, when the spring flood peak typically occurs only at the turn of May and June. In May and June, the water level is forecast to remain significantly lower than usual.

The water level of Lake Saimaa is near the average level for the time period. The water level is forecast to rise by no more than 15 cm by the end of May. The water level typically rises by 30–40 cm in May and June, but it is now forecast that the rise will stabilise at the end of May already, unless the spring is rainier than normal. Without heavy rainfall, the water level in Lake Saimaa will be clearly lower than usual next summer.
