Low Streamflow Advisory – Vancouver Island
ENDED: September 3, 2015 4:30 PM

The River Forecast Centre is ending the low streamflow advisory for:

  • Vancouver Island

The recent rainfall events on Vancouver Island have improved streamflow conditions for most of the island’s streams. Currently, streams on the west coast and in northern areas of Vancouver Island are well above normal conditions for this time of year. Some streams are still rising, while others have stabilized at flows above normal conditions. Streamflow conditions on the east side of Vancouver Island have also improved this week and most natural streams are above normal for this time of year. Some of the regulated streams are currently above critical low flow levels, but still below normal flow conditions for this time of year.
Environment Canada forecasts 40 to 60 mm of rainfall and seasonal temperatures for most of Vancouver Island over the next 10 days. It is anticipated that streamflows will continue to improve pending the precipitation forecast.
The River Forecast Centre will continue to monitor conditions and will provide updates as conditions warrant.

 Conditions noted in this advisory are based on provisional data from the Water Survey of Canada (WSC) that are subject to final quality-control per the WSC. In some instances, particularly at extreme low flow conditions, the rating curve at a WSC station may not be well-calibrated and may result in a variance between the reported provisional streamflow data and field-measured flow data.
