Earlier this week, the Nicomekl River spilled its banks into the floodplain and beyond. I posted in September about the river measurement station near the 203rd Street Bridge. This morning, I looked at the historical flows since Environment Canada put the measurement station into service in 1985.
Previous to this week, the maximum flow was 61.6 m3/sec in 2009. On Monday, November 15th, the flow was 76.9 m3/sec.

Environment Canada started taking level measurements in 2011.

All that to say, Langley City experienced the highest level of the Nicomekl River and most localized flooding in my lifetime.
