Flood Warnings and Advisories

Northeast Region - Flood Watch – Cariboo (MAINTAINED)
ISSUED: 8:15 AM May 6, 2020

The River Forecast Centre is maintaining a Flood Watch for:

  • Cariboo and including tributary rivers and streams near Williams Lake and Quesnel and areas east, including the San Jose River, Bridge Creek

Flows remain high in some regions, particularly on the San Jose River and areas to the east of Williams Lake, Quesnel and 100 Mile House including Bridge Creek, areas around Horsefly, and and watersheds draining from the western edge of the Cariboo Mountains, including the Cottonwood River. In mid-elevation terrain (1400-1600m) there is still some snow cover allowing for the maintenance of high flows due to snowmelt.
Current reported river conditions as of 7:00AM Wednesday May 6th include:

  • San Jose above Boreland Creek (08MC040) is estimated to be flowing at 20 m3/s (above a 20-year flow) and slowly receding
  • Bridge Creek below Deka Lake (08LA027) is flowing at 24 m3/s (50-year flow) and rising
  • Moffat Creek near Horsefly (08KH019) is flowing at 35 m3/s (5-year flow) and fluctuating

A frontal system is expected to track over British Columbia today, with the potential for some showers through the region, and higher rainfall amounts in the Cariboo Mountains. As the rest of the week progresses, a high pressure ridge is expected to develop over British Columbia, with temperatures warming into the weekend. River levels in areas with high flows now are expected to continue to remain elevated, with the potential for increasing flows with snowmelt into the weekend.


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.
