ISSUED: 8:45 AM May 6, 2020
The River Forecast Centre is issuing a High Streamflow Advisory for:
- Tributaries of the North Thompson River around Clearwater and Barriere
The River Forecast Centre is maintaining a High Streamflow Advisory for:
- Cache Creek and Bonaparte River and surrounding areas
- Upper Nicola River above Nicola Lake
- North Okanagan including tributaries around Vernon, Lumby and Winfield
- Salmon River near Salmon Arm
Snowmelt runoff has been contributing to rising flows in most areas over the past week or two. Rainfall occurred over the region in the past 24 hours, with precipitation totals in the 5-15 mm range being observed at Fire Weather Stations across the region. River levels have been responding to snowmelt and rainfall.
Current reported river conditions as of 7:00AM Wednesday May 6th include:
- Fishtrap Creek near McLure (08LB024) is flowing at 9m3/s (5-year flow)
- Bonaparte River below Cache Creek (08LF002) is flowing at 60 m3/s (10-year to 20-year flow) and has risen slightly over the past couple of days
- Salmon River at Falkland (08LE020) is flowing at 27 m3/s (2-year and 5-year flow) and has eased slightly over the past two days
- Nicola River at Outlet of Douglas Lake (08LG028) is flowing at 46 m3/s and has eased slightly over the past two days
- Coldstream Creek above Municipal Intake (08NM142) is flowing at 4 m3/s (10-year flow) and has eased slightly over the past two days
- Bessette Creek above Beaverjack Creek (08LC039) is flowing at 19 m3/s (approaching a 2-year flow) and has eased slightly over the past two days
A frontal system is expected to track over British Columbia today, with the potential for some showers through the region, and higher rainfall amounts (possible 10-30mm) forecast in the Cariboo Mountains and Monashees. Areas in the Cariboo Mountains (tributaries to the North Thompson River around Barriere, Clearwater and McLure) and the Monashees and North Okanagan (including areas around Vernon, Lumby, Enderby, and Sicamous) may see significant river rises today and into tomorrow if heavier showers materialize in watersheds.
As the rest of the week progresses, a high pressure ridge is expected to develop over British Columbia, with temperatures warming into the weekend, with increasing flows expected for rivers with mid-to-high elevation snowpacks 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.
