High risk of flooding around Dawson City, Yukon, as late spring thaw arrives

High risk of flooding around Dawson City, Yukon, as late spring thaw arrives

The latest ice breakup forecast for Yukon suggests there may be some flooding in the Dawson City area this spring, though not likely in town. "We assess the flood risk as low for Dawson City proper, the town itself, because it is protected by the dike," said Anthony Bier, the Yukon government's acting senior hydrologist. It's been a cool spring so far in the Dawson area, and a lot of snow fell over the winter. The amount of snow on the ground — called the snowpack — is higher than it usually is, meaning more water hitting the rivers once things start melting.

Freshwater scientists and biologists in B.C.'s Cowichan Valley say marine life in the area is thriving this spring, with the combination of heavy rainfall and late spring thaw resulting in higher water levels in rivers and other waterways. "For river levels, generally at this time of year we like to see ... seven to 15 cubic metres per second. This year, we're running about 30," said Tom Rutherford, the executive director of the Cowichan Watershed Board. He said in his 30 years of experience, he's never seen water levels this high.
