Flood Warnings and Advisories

Flood Warning – Chilako River, Cache Creek, Cariboo, Chilcotin (MAINTAINED)
High Streamflow Advisory – Nazko/West Road River (DOWNGRADED), Dean River, Salmon River near Salmon Arm (ISSUED)
ISSUED: 10:30 AM April 26, 2020

The River Forecast Centre is maintaining a Flood Warning 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 and surrounding areas

The River Forecast Centre is downgrading to a High Streamflow Advisory for:

  • Nazko River and West Road River

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

  • Salmon River near Salmon Arm
  • Dean River

Snowmelt rates have eased over the past few days and many rivers through the regions have reached peak levels and are holding steady or have eased slightly. In the Nazko and West Road River region flows have decreased steadily over the past few days. 


A frontal system moved through BC on Saturday, bringing light to moderate showers and isolated thundershowers across the Interior. Precipitation amounts were light (5-10 mm) and temperatures were cold enough that freezing levels dropped, and snow accumulated over higher elevations.


Current reported river conditions as of 7:00AM Sunday April 26th include:

  • West Road River near Cinema (Water Survey of Canada gauge 08KG001) is flowing at 200 m3/s which is between a 2 & 5-year return period.  After previously reaching a 50-year return period. Similar conditions are expected upstream in the Nazko River.
  • Baker Creek at Quesnel (08KE016) gauge has malfunctioned, but models are simulating a recent decline in flows.
  • San Jose above Boreland Creek (08MC040) is estimated to be flowing at 15-25 m3/s (10-year to 50-year flow) and slowly receding
  • Bonaparte River below Cache Creek (08LF002) is flowing at 73 m3/s (20-year to 50-year flow) and staying steady over the past 24 hours. Continued rises are possible next week.
  • Chilako River upstream of the Highway 16 bridge has crested early Saturday and has slowly lowered by 12 cm.  It is likely to continue receding slowly unless there is significant precipitation or sudden increase in temperature.
  • Dean River below Tanswanket Creek (08FC003) is flowing at 134 m3/s (5-year flow) and is staying fairly steady.
  • Salmon River near Salmon Arm (08LE021) and Salmon River at Falkland (08LE020) are slowly rising and nearing 2-year flow.  Forecasts indicate the river may reach 5-year flows next week.

Cooler temperatures over the past few days have subdued flows through most of the province.

Currently, there are no major weather patterns forecast for the upcoming week and flows are not expected to rise suddenly.

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 conditions 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.
