Flood Warnings and Advisories

South-East Region: High Streamflow – Boundary, West Kootenay, East Kootenay, Upper Columbia
ISSUED: 11:30 AM June 5, 2020

The River Forecast Centre is maintaining a High Streamflow Advisory for:

  • Boundary Region including the Kettle River, West Kettle River, Granby River and tributaries
  • West Kootenay including the Slocan River, Salmo River and surrounding tributaries
  • East Kootenay including the Moyie River and surrounding tributaries
  • Upper Columbia Region

River levels have generally eased across the region this week, compared to the high flows experienced earlier this week and last weekend. Most rivers in the region are now at or below the 2-year to 5-year return period flow levels.

Unsettled weather is expected to continue into the weekend, with the potential for more organized rainfall on Sunday and into Monday. Rivers are expected to experience rises late-weekend and into early next week in response to this rainfall. At this time, forecasts are not indicating that rivers will reach levels that were experienced earlier in the week. Flows in the 2-year to 5-year range are possible.

The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high-streamflow period.

The River Forecast Centre continues to monitor the situation and provides updates as conditions warrant.
