DOWNGRADED: High Streamflow Advisory. Central & Southern Vancouver Island. February 3, 2020



The River Forecast Centre is downgrading the Flood Watch to a High Streamflow Advisory for Central Vancouver Island including:

  • Central Vancouver Island (Ash River, Sproat River, Somass River)
  • Southern Vancouver Island (Cowichan River)

Most rivers have returned to normal levels, except for rivers influenced by lakes. The Cowichan River, Ash River, Sproat River and Somass River have been downgraded to High Streamflow Advisory. There are no expectations for these rivers to increase over the next few days. However, the flows are receding slowly and are still considerably high relative to normal February levels.

The River Forecast Centre continues to monitor the conditions and will provide updates as conditions warrant.


A High Streamflow Advisory means that river levels are rising or expected to rise rapidly, but that no major flooding is expected.  Minor flooding in low-lying areas is possible.

A Flood Watch means that river levels are rising and will approach or may exceed bank-full.  Flooding of areas adjacent to affected rivers may occur.

A Flood Warning means that river levels have exceeded bank-full or will exceed bank-full imminently, and that flooding of areas adjacent to the rivers affected will result.
