Water is expected to overflow due to the Chilcotin River landslide in central British Columbia on Sunday night or early Monday.
In an update provided through the provincial government on Sunday afternoon, on existing modeling, it is predicted that water will begin to overcome the blockage and enter the river bed.
“There was minimal water flow through the dam created with topsoil on Tuesday, July 30, 2024, so the water point behind the dam has continued to rise over the past few days,” he said. the province in a press release.
“It’s expanding at a rate of about 18 centimeters per hour. “
The most productive and most likely scenario is that it would take 12 to 24 hours longer for the trapped water to break through and overcome the blockage.
This is expected to result in flows below the spring flood peaks of the Fraser River, but well above the peaks of the Chilcotin River.
“Under the 12-hour scenario, Chilcotin River peak flows may be more than 10 times greater than the typical fresh peak flow,” the province said. “In the 24-hour scenario, the peak flow may simply be “More than seven times the typical peak flood flow. “
The #BC River Forecast Center is upgrading to a Flood WARNING for the Chilcotin River downstream of the landslide near Farwell Canyon.

People are asked to stay away from the Chilcotin River Valley between Hanceville and the confluence of the Fraser River. An evacuation order issued through the Cariboo Regional District remains in effect. People should also stay away from the banks of the Fraser River.
The province said that it is for all scenarios since the model does not give guarantees.
Real-time water point tracking data is publicly available through the Water Survey of Canada.
The provincial government has also introduced a new internet portal to provide the latest data on the Chilcotin River landslide.
