Breakup of the Yukon River over the weekend has led to serious flooding in Eagle, Circle and Fort Yukon.

As Alaska faces an increased risk of spring breakup flooding this year, scientists are asking residents to share photos documenting major rivers’ progress from ice to water to help them predict with more accuracy where flooding might occur.

Residents in the northern Alberta community of Chateh, west of High Level, could be out of their homes for several months after flooding forced them to evacuate Sunday and Monday. 'This is the worst flooding we ever had,' Dene Tha' First Nations chief says.

Rainfalls of unprecedented intensity caused flash floods in several parts of the country and serious flooding in Bayan-Ulgii, Selenge and Tuv aimag.

Heavy rain and winter runoff in the month of May has affected more than people's homes along the Ottawa River. The river itself, often polluted with sewage overflow after a day or two of heavy rain, has had to absorb more than 600-million litres over the past week alone.
