Flood Warnings and Advisories
Central Region - Flood Watch – Cache Creek/Bonaparte
High Streamflow Advisory – Upper Nicola River (NEW), Salmon River (Salmon Arm)
ISSUED: 8:30 AM May 1, 2020
The River Forecast Centre is maintaining a Flood Watch for:
- Cache Creek and Bonaparte River and surrounding areas
The River Forecast Centre is issuing a High Streamflow Advisory for:
- Upper Nicola River above Nicola Lake
The River Forecast Centre is maintaining a High Streamflow Advisory for:
- Salmon River near Salmon Arm
Snowmelt rates have increased slightly over the past day or two. In some areas snow packs are dwindling (particularly below 1300-1400m) leading to an easing on river levels. In mid elevations (1400-1600m) some snow remains with 20-50% of this seasons snow being observed at mid-elevation automated snow weather stations (e.g. Brenda Mines, Trout Creek, Shovelnose). This snow is expected to melt over the next 1-2 weeks.
Watersheds that still contain terrain over 1400m are seeing levelling of flows, or flow increases, and remain sensitive to additional rises in the short-term over this weekend. This includes the Bonaparte River and the Upper Nicola River.
- Bonaparte River below Cache Creek (08LF002) is flowing at 62 m3/s (10-year to 20-year flow) and slowly receding
- Salmon River at Falkland (08LE020) are slowly rising and flowing at 23.4 m3/s (2-year and 5-year flow)
- Nicola River at Outlet of Douglas Lake (08LG028) is flowing at 38.5 m3/s with flows holding steady with slight day-to-day variation but remaining high
A ridge is expected to build today, with some warming of temperatures. In areas with snowpack remaining this will lead to a modest increase in snowmelt rates and potential rise in rivers. Over the weekend a low-pressure system is expected to impact the province, with rainfall primarily focused on the west side of the Coast Mountains, with some showers and rain into the Interior. Rises in river levels over the weekend are possible.
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.
