16 Widespread flooding commences with the 100 year flood being affected at a stage height of 15.8 feet.
11 Flooding will be occurring in the town of Surprise. This level is similar to the flood experienced in 2008.
10 Water reaches the bottom of the bridge near the gage. The resulting backwater will eventually close Miller Street, also known as County Road D going south of town.
7 County road 24 1/2 will begin to flood downstream of Surprise. In addition, the city park near the gage site begins to flood.
