The following Flood Warnings, Watches and Advisories in the North-East and North-West regions are MAINTAINED as of Friday, May 18th  1530hr:

  • Flood Warning – Bulkley River including tributaries around Houston, Smithers and adjacent areas
  • Flood Watch Fraser River at Prince George through Quesnel
  • Flood Watch – Nautley River and Nechako River including tributaries and lake levels around Burns Lake, Francois Lake, Vanderhoof and surrounding areas
  • Flood Watch – Dean River
  • High Streamflow Advisory – Nazko and West Road River
  • High Streamflow Advisory – Prince George area including the Chilako River, Salmon River and surrounding tributaries

Hot weather led to rapid snow melt from mid-to-upper elevation snow packs. Temperatures are cooling slightly into the weekend, so rivers levels with sufficient snow remaining will likely experience a leveling off or slight drop.  Well above normal temperatures are forecast for next week, and river levels are expected to increase again in areas with snow. 
A summary of key rivers includes:

  • Fraser River at South Fort George (08KE018) is at 9.13m (near a 5-year water level), and is expected to stay fairly level over the weekend and begin to drop slightly at the start of next week
  • Bulkley River near Houston (08EE003) is flowing at 176 m3/s (5-year flow) and is receding. Snowpack in the basin is depleted and risks of additional snowmelt related rises in level is being reduced
  • Bulkley River near Smithers (08EE005) is flowing at 1080 m3/s (between a 5-year and 10-year flow). Flows may reach up to the 1200-1300 m3/s range through this weekend due to possible rain and may exceed previous peak levels from last week
  • Nautley River near Fort Fraser (08JB003) is flowing at 268 m3/s (between a 20-year and 50-year flow). The rate of rise has eased the last two days and is expected to remain elevated
  • Nechako River near Vanderhoof (08JC001) is currently flowing at 455 m3/s (between a 2-year and 5-year flow), and has eased the past six days. Flows are expected to remain at a similar level

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