Hot temperatures since the weekend have led to significant snow melt, and rising river levels. Thundershowers and rain over the past 24 hours has added to this runoff. Precipitation totals since yesterday have been in the 5-25 mm range, with the highest amounts of precipitation being observed in the East Okanagan, Shuswap, Kettle and West Kootenay regions.

Current flow conditions and outlook include:

  • Slocan River near Crescent Valley (Water Survey of Canada gauge 08NJ013) is flowing at approximately 670 m3/s. Additional rainfall is expected on Thursday and flows are expected to additional rises into Friday. Flows in the 700-750 m3/s are possible, depending on additional rainfall amounts.
  • Kettle River near Westbridge (WSC gauge 08NN026) is flowing at approximately 270 m3/s (5-year flow). Additional rises are expected into Friday and depending on rainfall amounts on Thursday, may reach or exceed levels experienced so far this season.
  • Flows on the Kettle River downstream through to Grand Forks are expected to rise through Thursday and into Friday. Depending on additional rainfall on Thursday, flows may reach up to levels previously experienced earlier this season.
  • Mission Creek near East Kelowna (08NM116) reached approximately 70 m3/s (approaching a 5-year flow). If rainfall over the next 24 hours is heavy in the watershed (10-20mm), additional rises up to 100 m3/s are possible.
  • North Thompson River at McLure (08LB064) is flowing at 2180 m3/s (between a 5-year and 10-year flow). Additional rises are expected through Thursday.
  • South Thompson River at Chase (08LE031) is flowing at 980 m3/s (2-year flow) and rising. Steady rises are expected through the rest of the week with forecasted flows in the 1200 m3/s range (5-year to 10-year flow) by the weekend.

Additional rainfall is expected to fall today, with additional amounts in the 5-25mm range forecast through the region. Currently areas around the east Okanagan, Boundary and West Kootenay are expected to see the highest rainfall amounts on Thursday.

The River Forecast Centre will continue to monitor conditions and will update the advisory as conditions warrant.

A High Streamflow Advisory means that river levels are rising or expected to rise rapidly, but that no major flooding is expected.  Minor flooding in low-lying areas is possible.
A Flood Watch means that river levels are rising and will approach or may exceed bankfull.  Flooding of areas adjacent to affected rivers may occur.
A Flood Warning means that river levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result.

Hot temperatures since the weekend have led to significant snow melt, and rising river levels. Weather is expected to shift through Tuesday, with potential showers in the western areas of the region, and shifting Wednesday further eastward. Easing temperatures will reduce snow melt rates, however flows are expected to remain high, or rise higher, in response to the added precipitation.

Current flow conditions and outlook include:

  • Slocan River near Crescent Valley (Water Survey of Canada gauge 08NJ013) is flowing at approximately 520 m3/s. Flows are expected to rise to 550-570 m3/s into early Wednesday, and up to 600-650 m3/s over the Wednesday to Thursday period. If local rainfall exceeds 20mm on Wednesday-Thursday, higher flows are possible.
  • West Kettle River at Westbridge (WSC gauge 08NN003) is flowing at 135 m3/s (between a 2-year and 5-year flow). Additional rises are expected into Wednesday, and are currently expected to remain below flow levels experienced last week and earlier in May.
  • Mission Creek near East Kelowna (08NM116) reached approximately 60 m3/s earlier Tuesday (2-year flow). Additional rises into Wednesday are expected from snowmelt and precipitation. Flows are expected to remain below 10-year flow levels (80-90 m3/s) unless rainfall is higher than anticipated (5-15mm)
  • Coldwater River at Merritt (08LG010) is flowing at 65 m3/s (approaching a 2-year flow). Small additional rises are expected into Wednesday. Flows are expected to remain below flows experienced last week unless rainfall is higher than anticipated (5-15mm).

  • North Thompson River at McLure (08LB064) is flowing at 1860 m3/s (2-year flow) and is expected to see on-going rises through Thursday. Flows are expected to reach the 2000-2200 m3/s range (5-year to 10-year flow). Flows are expected to recede into the weekend.
  • South Thompson River at Chase (08LE031) is flowing at 980 m3/s (2-year flow) and rising. Steady rises are expected through the rest of the week with forecasted flows in the 1200 m3/s range (5-year to 10-year flow) by the weekend.
