Flood Warnings and Advisories
Flood Warning – Chilako River (UPGRADED), Cache Creek, Cariboo, Chilcotin, Nazko/West Road River (MAINTAINED)
ISSUED: 8:00 AM April 24, 2020
The River Forecast Centre is upgrading to a Flood Warning for:
- Tributary rivers and streams around Chilako and south-west of Prince George
The River Forecast Centre is maintaining a Flood Warning for:
- Cariboo and Chilcotin (Fraser Plateau) including tributary rivers and streams around Williams Lake, Quesnel, Alexis Creek, Anahim Lake, Cache Creek and surrounding areas
- Nazko River and West Road River
Snowmelt rates have eased over the past 2 days and many rivers through the region have reached peak levels and are holding or have eased slightly. In the Chilako River, river levels have continued to rise, however the rate of rise has been slowing since yesterday.
A frontal system is expected to pass over the BC Coast on Saturday and may bring light to moderate showers and potential thundershowers across the Interior. Precipitation amounts are forecast to be light (5-10 mm) with the potential for localized pockets of high amounts. Temperatures should ease over this period, with freezing levels dropping and the potential for snow over higher terrain.
Snow packs are dwindling in the headwaters of many of the Interior Plateau rivers, and snowmelt runoff is expected to ease through the weekend.
Current reported river conditions as of 7:00AM Thursday April 24th include:
- West Road River near Cinema (Water Survey of Canada gauge 08KG001) has experienced slight easing in river levels with a drop of 10-20cm at the gauge since yesterday. Similar conditions are expected upstream in the Nazko River.
- Baker Creek at Quesnel (08KE016) has been holding steady since yesterday
- San Jose above Boreland Creek (08MC040) is estimated to be flowing at 25-35 m3/s (50-year to 100-year flow) and holding steady
- Bonaparte River below Cache Creek (08LF002) is flowing at 63 m3/s (20-year flow) and rising. Continued rises are expected today and potentially into the weekend
- Chilako River upstream of the Highway 16 bridge has risen nearly 35 cm since yesterday, with continued rises expected today and potentially into the weekend
While there are early signs that river levels may be approaching or at peak levels, showers and on-going snowmelt into the weekend should keep river levels high and may lead to additional rises. Current modelling is indicating the potential for additional rises over the weekend. Continued rises are expected on the Bonaparte River and the Chilako River due to snowmelt.
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.
