19	Widespread major flooding begins of the marshy wetlands and woods along the creek upstream and downstream from the stream gage on the Hammett Road bridge. Two houses and outbuildings on the right bank near the bridge are flooded with several feet of water. The Hammett Road bridge begins to form an obstacle and act like a dam causing some backwater and erosion eddies to the sides of the bridge. The water begins to flood Hammett Road in low lying areas and will likely be closed by county officials.
16	Widespread moderate flooding continues to expand further into the marshy wetlands and woods along the creek upstream and downstream from the stream gage on the Hammett Road bridge. Two houses and outbuildings on the right bank near the bridge are flooded with several feet of water. The water level reaches the bottom of the Hammett Road bridge and it may be closed by county officials.
15	Widespread moderate flooding begins of the marshy wetlands and woods along the creek upstream and downstream from the stream gage on the Hammett Road bridge. Two houses and outbuildings on the right bank near the bridge will be flooded with a few feet of water.
13	Minor flooding continues to expand further into the marshy wetlands and woods along the creek upstream and downstream from the stream gage on the Hammett Road bridge. Two houses and some outbuildings on the right bank near the bridge will be flooded.
11	Minor flooding continues to expand further into the marshy wetlands and woods along the creek upstream and downstream from the stream gage on the Hammett Road bridge. Yards of nearby homes will be flooded and the water reaches the foundation of a house on the upstream and right bank of the bridge.
10	Minor flooding continues to expand further into the marshy wetlands and woods along the creek upstream and downstream from the stream gage on the Hammett Road bridge. Yards of nearby homes will be flooded.
8	Minor flooding begins of the marshy wetlands and woods along the creek upstream and downstream from the stream gage on the Hammett Road bridge.
6	Bankfull is reached along the creek upstream and downstream from the stream gage on the Hammett Road bridge.
