25 Major flooding begins with widespread inundation along the river. The Flakes Mill Road bridge forms an obstacle and acts like a dam causing some backwater and erosion eddies to the sides of the bridge. The service road leading to the Snapfinger Advanced Wastewater Treatment Facility will be under water. The west and south sides of the property will be completely flooded with water spilling into the holding areas of the Inflow Channel. Some homes on Roundtable and English Valley Drives will begin to flood.
23 Significant flooding expands further from the river. The Flakes Mill Road bridge begins to form an obstacle and act like a dam causing some backwater and erosion eddies to the sides of the bridge.
