28	Major flooding begins. Widespread inundation flooding occurs along the river and expands further into the woodlands and farmland downstream from the gage at Old U.S. Highway 411 and upstream to the recreation area by the gates of the Carters Reregulation Lake. The water level will reach the bottom of the bridge. Portions of the recreation area will be under 10 feet of water. The fishing piers will be under at least 11 feet of water.
26	Significant flooding along the river expands further into the woodlands and farmland downstream from the gage at Old U.S. Highway 411 and upstream to the recreation area by the gates of the Carters Reregulation Lake. Portions of the recreation area will be under 8 feet of water. The fishing piers will be under at least 9 feet of water.
24	Moderate flooding begins. Significant flooding occurs along the river in the woodlands and farmland downstream from the gage at Old U.S. Highway 411 and upstream to the recreation area by the gates of the Carters Reregulation Lake. Portions of the recreation area will be under 6 feet of water. The fishing piers will be under at least 7 feet of water.
22	Minor flooding along the river continues to expand in the woodlands and farmland downstream from the gage at Old U.S. Highway 411 and upstream to the recreation area by the gates of the Carters Reregulation Lake. Portions of the recreation area will be under 4 feet of water. The fishing piers will be under at least 5 feet of water.
21	Minor flooding along the river continues to expand in the woodlands and farmland downstream from the gage at Old U.S. Highway 411 and upstream to the recreation area by the gates of the Carters Reregulation Lake. Portions of the recreation area will be under 3 feet of water. The fishing piers will be under at least 4 feet of water.
20	Flood stage is reached. Minor flooding occurs along the river in the woodlands and farmland downstream from the gage at Old U.S. Highway 411 and upstream to the recreation area by the gates of the Carters Reregulation Lake. Portions of the recreation area will be under two feet of water. The fishing piers will be under at least 3 feet of water.
19	Bankfull conditions along the river expand further into the woodlands and farmland downstream from the gage at Old U.S. Highway 411 and upstream to the recreation area by the gates of the Carters Reregulation Lake. Portions of the recreation area will be under a foot of water. The fishing piers will be under at least two feet of water.
18	Bankfull conditions along the river continue in the woodlands and farmland downstream from the gage at Old U.S. Highway 411 and upstream to the gates of the Carters Reregulation Lake. Portions of the recreation area will begin to flood and the fishing piers will be under at least a foot of water.
17	Bankfull conditions are reached in low lying areas of woodlands and farmland downstream from the gage at Old U.S. Highway 411 and upstream to the gates of the Carters Reregulation Lake. The fishing piers at the recreation area by the gates will begin to flood.
