21 Major flooding continues with widespread inundation of the woodlands and grassy areas along the creek upstream and downstream from the gage behind a DeKalb County Pump Station off Rock Chapel Road. Flood waters will be up to 14 feet deep in the grassy areas. The water level will be around 7 feet above the center manhole cover of a sanitary sewer. The flood waters will begin to enter the pump station building and be around two feet deep over the paved area.
20 Major flooding occurs with widespread inundation of the woodlands and grassy areas along the creek upstream and downstream from the gage behind a DeKalb County Pump Station off Rock Chapel Road. Flood waters will be up to 13 feet deep in the grassy areas. The water level will be around 6 feet above the center manhole cover of a sanitary sewer and be reaching the foundation of the pump station. The flood waters will be around one foot deep over the paved area around building.
19 Major flooding begins. Widespread inundation occurs of the woodlands and grassy areas along the creek upstream and downstream from the gage behind a DeKalb County Pump Station off Rock Chapel Road. Flood waters will be up to 12 feet deep in the grassy areas. The water level will be around 5 feet above the center manhole cover of a sanitary sewer. The lowest portion of the paved area around the pump station will begin to flood.
18 Significant flooding continues to expand into the woodlands and grassy areas along the creek upstream and downstream from the gage behind a DeKalb County Pump Station off Rock Chapel Road. Flood waters will be up to 11 feet deep in the grassy areas. The water level will be around 4 feet above the center manhole cover of a sanitary sewer. The lowest portion of the paved area around the pump station will begin to flood.
17 Significant flooding continues to expand into the woodlands and grassy areas along the creek upstream and downstream from the gage behind a DeKalb County Pump Station off Rock Chapel Road. Flood waters will be up to 10 feet deep in the grassy areas. The water level will be around 3 feet above the center manhole cover of a sanitary sewer.
15 Significant flooding continues in the woodlands and grassy areas along the creek upstream and downstream from the gage behind a DeKalb County Pump Station off Rock Chapel Road. Flood waters will be from 7 to 8 feet deep in the grassy areas. The water level will be around one foot above the center manhole cover of a sanitary sewer.
14 Moderate flooding begins. Significant flooding occurs in the woodlands and grassy areas along the creek upstream and downstream from the gage behind a DeKalb County Pump Station off Rock Chapel Road. Flood waters will be from 6 to 7 feet deep in the grassy areas. The water level will reach the top of the center manhole cover of a sanitary sewer.
13 Minor flooding continues to expand further into woodlands and grassy areas along the creek upstream and downstream from the stream gage behind a DeKalb County Pump Station off Rock Chapel Road. Flood waters will be from 5 to 6 feet deep in the grassy areas.
11 Minor flooding continues in the woodlands and grassy areas along the creek upstream and downstream from the stream gage behind a DeKalb County Pump Station off Rock Chapel Road. Flood waters will be from 3 to 4 feet deep in the grassy areas.
9 Flood stage is reached. Minor flooding occurs in the woodlands and grassy areas along the creek upstream and downstream from the stream gage behind a DeKalb County Pump Station off Rock Chapel Road. Flood waters will be from 1 to 2 feet deep in the grassy areas.
