Flood Watch – South Thompson (Maintained)
High Streamflow Advisory – North Thompson River (MAINTAINED), Thompson River (MAINTAINED)
ISSUED: 5:00 PM June 28th, 2020
The River Forecast Centre is maintaining a Flood Watch for:
- South Thompson River
The River Forecast Centre is maintaining a High Streamflow Advisory for:
- North Thompson River including Blue River, Clearwater River and surrounding tributaries
- Thompson River at Kamloops and downstream to Spences Bridge
- Tributaries of the South Thompson including Shuswap River, Shuswap Lake, Adams River
Precipitation ranging from 5 to 30 mm fell late Friday and into Saturday in the North and South Thompson. The additional rain has maintained flows at a fairly high level after the recent rises from rainfall earlier last week.
Most recent observations are:
- North Thompson River at Birch Island (08LB047) peaked late on Thursday at 834 m/s (5-year flow). The river is currently flow at 700 m3/s
- North Thompson River at McLure (08LB064) peaked at 2140 m3/s (5-year flow) around noon on Friday. It has remained steady and is currently flowing at 2100 m3/s
- Clearwater River near Clearwater Station (08LA001) peaked early on Thursday at 1260 m3/s (10-year flow). The river is currently flowing at 1150 m3/s
- South Thompson at Chase (08LE031) is flowing at 1320 m3/s (10-year flow) and gradually rising
- Thompson River near Spences Bridge (08LF051) is flowing at 3400 m3/s (between a 5-year and 10-year flow) and gradually rising
Rising flows from the South Thompson River and the North Thompson River are increasing water levels on the Thompson River at Kamloops and downstream. The Thompson River at Kamloops continues to increase to the highest level of the season. The Thompson River at Spences Bridge is expected to continue to increase over the next couple days and could reach a 10-year flow.
These large systems are very high for this time of year, which makes them incredibly vulnerable to another widespread rainfall event. Weather forecasts show continued unsettled weather patterns for the upcoming week.
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.
