Summer mudslides are causing concern after bushfires left the slopes vulnerable – the Okanagan

Three landslides in Summerland’s Garnet Valley sent rocks, water and debris onto the Campbell family’s property this week, highlighting the ongoing risk posed by slopes burned in this summer’s Bald Range wildfires.

The avalanche was triggered by heavy rain on Tuesday, with debris falling onto fields on the family’s property.

“It’s a rock wall and the water flows into the fields there,” said Marty Campbell of Campbell Creek Farm.

The family said the incident was a reminder that the danger is not over when forest fires are contained.

Fires in the Bald Range are burning vegetation along slopes, making the soil more susceptible to erosion and raising concerns about landslides during periods of heavy rain.

For Shawn Campbell, the possibility of another slump is a major worry.

“If the mountain behind us collapsed and went straight into our house, that’s probably our biggest fear right now,” he said.

The Regional District of Okanagan-Similkameen (RDOS) is monitoring the potential impacts of heavy rain, while geotechnical assessments are being conducted in the affected areas.

Erick Thompson, information officer at the RDOS Emergency Operations Center, said the regional district is working directly with residents who may be impacted.

“RDOS is certainly looking at the potential impacts to properties from heavy rainfall,” Thompson said.

“Sand and sandbags were also given directly to residents,” he added.

The landslide comes as BC’s Ministry of Forests released a report outlining increased danger following this summer’s bushfire season.

The report shows that the likelihood of additional landslides varies depending on the terrain, with risks ranked from low to high.

Highway 97 was also identified as an area of ​​concern. The report assesses the likelihood of spatial impacts to roads and private property on the overlying slopes as high.

The Ministry of Transportation directed Global News to the Ministry of Forestry for comment. With a new provincial government yet to be inaugurated, communication remains limited while the government operates in caretaker mode.

The risks are not limited to Summerland.

The Central Okanagan Regional District has also warned of increased danger associated with the Quilchena fire south of La Casa, including concerns around the Westside Road area.

For residents experiencing forest fires this summer, the possibility of landslides and flooding adds another layer of uncertainty.

At Campbell Creek Ranch, the fire had burned to the front door of the family’s home. They stayed to defend their possessions and managed to save their livestock.

Now, after making it through the forest fires, they face another threat.

“The fire was burning right outside our door. We were able to stay and put it out and save all our livestock, horses and chickens, and we thought we were through,” said Shawn Campbell.

“And now it’s a flood watch.”

For the Campbell family, Tuesday’s landslide was a reminder that the impact of wildfires can continue long after the flames are out.
