What Floods at Each Level
32 ft
Record flooding causes widespread inundation of the woodlands...fields and pastures upstream and downstream from the gage at Brownsville Road. Flood waters will be around 10 feet deep over portions of the road and will have topped the bridge with 4 feet of water. The water level will be around 3 feet deep in a house on the downstream and right bank of the creek. The USGS gage house will be under water. This flooding will be worse than September 2009.
31 ft
Near record flooding expands further with widespread inundation of the woodlands...fields and pastures upstream and downstream from the gage at Brownsville Road. Flood waters will be around 9 feet deep over portions of the road and will have topped the bridge with 3 feet of water. The water level will be around two feet deep in a house on the downstream and right bank of the creek. The USGS gage house will be under water. This flooding will be similar to the September 2009 major flood event.
29 ft
Major flooding expands with widespread inundation of the woodlands...fields and pastures upstream and downstream from the gage at Brownsville Road. Flood waters will be around 7 feet deep over portions of the road and will have topped the bridge with one foot of water. The water level will reach the floor level of a house on the downstream and right bank of the creek and inundate the USGS gage house. This will likely affect the data transmission.
28 ft
Major flooding continues with widespread inundation of the woodlands...fields and pastures upstream and downstream from the gage at Brownsville Road. Flood waters will be around 6 feet deep over portions of the road just northeast of the bridge. The bridge will be topped with the water level reaching the crawl space of a house on the downstream and right bank of the creek. The water level will also be close to the bottom of the USGS gage house which may affect the data transmission.
25 ft
Major flooding begins. Widespread inundation flooding occurs in the woodlands...fields and pastures upstream and downstream from the gage at Brownsville Road. Flood waters will be around 3 feet deep over portions of the road just northeast of the bridge. The water level will likely cause extensive erosion to the banks as the water flow hits the bridge. County officials will have the road and bridge closed.
24 ft
Significant flooding expands much further into the woodlands...fields and pastures upstream and downstream from the gage at Brownsville Road. Flood waters will be around two feet deep over portions of the road just northeast of the bridge. The water level will likely cause extensive erosion to the banks as the water flow hits the bridge. County officials will have the road and bridge closed.
22 ft
Significant flooding continues to expand further into the woodlands...fields and pastures upstream and downstream from the gage at Brownsville Road. Flood waters will begin to flow over portions of the road just northeast of the bridge. Also the water level will likely cause extensive erosion to the banks as the water flow hits the bridge. County officials will likely close the road and bridge.
21 ft
Significant flooding expands further into the woodlands...fields and pastures upstream and downstream from the gage at Brownsville Road. The water level will likely cause extensive erosion to the banks as the water flow hits the bridge. County officials may close the bridge.
20 ft
Moderate flooding begins. Significant flooding will expand into the woodlands...fields and pastures upstream and downstream from the gage at Brownsville Road. The water level will be close to the bottom of the bridge.
18 ft
Minor flooding continues to expand further into the woodlands...fields and pastures along the creek upstream and downstream from the gage at Brownsville Road.
15 ft
Minor flooding continues in the woodlands...fields and pastures along the creek upstream and downstream from the gage at Brownsville Road.
13 ft
Flood stage is reached. Minor flooding will occur in the woodlands...fields and pastures of the natural flood plain upstream and downstream from the gage at Brownsville Road.
10 ft
Bankfull conditions are reached along the creek upstream and downstream from the gage at Brownsville Road.
