Flood Warnings and Advisories

South-east Region - High Streamflow Advisory (MAINTAINED) – Boundary
ISSUED: 1:15 PM May 14, 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

Rivers have remained high through the region due snowmelt rates and some rainfall events over the past week. Snowmelt from mid-elevations is beginning to ease as areas become snow-free and it is expected that the peak runoff from snowmelt is currently underway.
River levels have remained stable over the past 2-3 days with drier conditions and easing temperatures. Flows are expected to remain high but stable over the next few days. Later this weekend and into early next week a pattern of unsettled weather is expected, with the potential for heavier amounts of precipitation. This may lead to another period of increased streamflow Sunday through Tuesday. At this time hydrologic modelling is indicating that flows through the Kettle and Granby Rivers should remain near or below 2-year to 5-year return period flows.


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.

Levels of Warnings/Advisories:

  1. High Streamflow Advisory: River levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible. This is the lowest level.
  2. Flood Watch: River levels are rising and will approach or may exceed bankfull. Flooding of areas adjacent to affected rivers may occur. This is the intermediate level.
  3. Flood Warning: River levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result. This is the highest level.
