High Water Event Overview

From May 5-9th, the City received 38mm of precipitation. Due to saturated soils, water levels in the creek rose and peaked on May 7th at 1pm. This caused the closure of the walking trail between 17th St. and Highway 97 South.

This flood event was identified as a 20% Annual Exceedance Probability. Annual Exceedance Probability is the probability that a flood of a given size will be exceeded in any one year.

Another area affected was the Dawson Creek Golf Course. Did you know the back nine of the Golf course is one of the lowest points along the Dawson Creek? When water levels rise, this area acts as a flood plain. This happens for floods of any size. Without this storage area, the creek would experience higher water levels downstream, and overland flooding would be more common within the City.
