Why it matters

For BC Hydro, managing large-scale water releases during periods of heavy rainfall and high river levels presents significant operational challenges. The need to issue advisories and manage the resulting flood risk requires substantial resource allocation and coordination with local emergency services.

The event is part of a broader pattern of severe weather across southwestern B.C., which has brought up to 306 millimetres of rain to Port Mellon in the Howe Sound region since Tuesday, leading to widespread flooding and road closures.

What we don't know yet
