Flood Warnings and Advisories

Flood Watch – Chilako River, Cariboo, Chilcotin, Cache Creek/Bonaparte (DOWNGRADED)
High Streamflow Advisory – Dean River, Salmon River (Salmon Arm)
High Streamflow Advisory – Nazko (ENDED)
ISSUED: 8:30 AM April 28, 2020

The River Forecast Centre is downgrading to a Flood Watch for:

  • Tributary rivers and streams around Chilako and south-west of Prince George
  • Cariboo and Chilcotin (Fraser Plateau) including tributary rivers and streams around Williams Lake, Quesnel, Alexis Creek, Anahim Lake, Cache Creek, Bonaparte River and surrounding areas

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

  • Salmon River near Salmon Arm
  • Dean River

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

  • Nazko River and West Road River

Snowmelt rates have eased over the past several days with cooling temperatures and in some locations overnight freezing. 
Most rivers have experienced a peak level and have been slowly declining over the last day or more.
Current reported river conditions as of 6:00AM Sunday April 28th include:

  • West Road River near Cinema (Water Survey of Canada gauge 08KG001) is flowing at 140 m3/s which is below a 2-year flow
  • Baker Creek at Quesnel (08KE016) gauge has been repaired and on-site water measurements taken yesterday. Current flow is estimated as 92 m3/s (5-year to 10-year flow) and receding
  • Sheridan Creek above McLeese Lake (08MC045) is flowing at 3.6 m3/s (2-year to 5-year flow) and receding
  • San Jose above Boreland Creek (08MC040) is estimated to be flowing at 13 m3/s (10-year to 50-year flow) and receding
  • Bonaparte River below Cache Creek (08LF002) is flowing at 69 m3/s (20-year to 50-year flow) and slowly receding
  • Chilako River upstream of the Highway 16 bridge has crested early Saturday and has slowly lowered by nearly 50cm.
  • Dean River below Tanswanket Creek (08FC003) is flowing at 124m3/s (2-year to 5-year flow) and receding
  • Salmon River near Salmon Arm (08LE021) and Salmon River at Falkland (08LE020) are slowly rising and between a 2-year and 5-year flow. 

Weather has shifted to a westerly flow pattern, with cooler temperatures and increased periods of showers through this week. Eased snowmelt rates and diminishing snow in low to mid-elevations (below 1400m) is expected to lead to continued easing of rivers. Rainfall patterns will continue to be monitored through this week, as more concentrated amounts of rainfall in the catchments with high flows may lead to additional increases in river levels.


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.
