High streamflow advisories are currently in effect for these regions of the BC interior, including the Boundary area where the Regional District of Kootenay Boundary is monitoring rivers and tributaries in the region.

“Rivers are expected to reach between a one and five year return based on current rain forecasts, which equates to an average to slightly above average freshet, but below 2017 levels that caused considerable low-elevation flooding, and well below 2018 levels that were catastrophic,” the RDKB said in a media release.

The RDKB continues to monitor all creeks and rivers and track BC River Forecast Centre model, will have emergency staff available through the long weekend and maintain its Emergency Operations Centre at a Level 2 for the next week in preparation for any emergency response that may be required.
