The flood risk for Upper Liard remains at moderate, and nothing in the forecast is raising any alarms, says the manager of the Emergency Measures Organization.
The flood risk for Upper Liard remains at moderate, and nothing in the forecast is raising any alarms, says the manager of the Emergency Measures Organization.
Michael Templeton said Monday the level of the Liard River is 1.4 metres below flood stage, and just five millimetres of rain were expected to fall up until Friday.
Yukon hydrologist Ric Janowicz has been predicting the river will probably rise to flood level but beyond that, nobody knows for sure, he said.
Templeton said Janowicz and EMO officials are monitoring the situation, as this week and next week are typically the time of year for peak levels in the Liard River.
The mountain snowpack in the Liard River watershed is 38 per cent above normal this spring, according to hydrology records.
"When we have had problems in the past, it is with the big rain events that have dropped a lot of rain,” he said.
In the rampant flooding across the southeast Yukon in 2012, recalled Templeton, the region received 70 millimetres of rain in two days.
He said the torrential downpour washed out a significant amount of snow remaining in the snowpack and caused the flood conditions that swept through the low lying areas around Upper Liard, including a small community.
The 2012 water level peaked at 1.9 metres above the flood stage, or 3.3 metres (11 feet) above where it was Monday, Templeton pointed out.
In the 2012 flood, some of the 11 homes on the east side of the Liard River Bridge at Upper Liard were under more than two metres of water.
All of the residents in the subdivision developed several decades ago by the Yukon government were bought out for a total of $3.5 million, of which $2.8 million was covered through the federal flood relief program.
Templeton said when the river level rises so does the ground water level, which may cause problems for some homes on the west side of the river.
As the river is expected to at least hit the flood stage, residents who have been affected by high water in the past may want to consider moving valuables from their basement or crawl space to higher ground, he said.
As far as he knows, however, when the river peaked last year at half of a metre above the flood stage, there were no basements nor crawl spaces affected.
Upper Liard is the only community with any threat of flooding at this stage.
The risk of flooding in the Marsh Lake, Carcross and Tagish areas is currently being described as low. The peak water level for the region normally occurs in August.
