CHILLIWACK — Daylight is giving emergency officials a good look at water levels across the Fraser Valley. A close eye is being kept on the potential impact of the Nooksack River flooding in Whatcom County south of the border.
According to data from U.S. officials, the peak of the flooding took place at 3. a.m. Thursday (Dec. 11) morning at the Nooksack River measuring station in North Cedarville in Washington State.
Water levels in the river peaked slightly above the 2021 peak which led to historic flood damage across the Fraser Valley. However several other factors will determine just how damaging flooding will be this time.
Water levels in the Nooksack River have been falling through the day and are forecast to fall below flood levels by Thursday evening.
