589	Near record flooding occurs upstream and downstream from Plant Hammond. Most of the access road behind the plant will be flooded up to 16 feet deep in some locations. Flood waters associcated with Cabin Creek will completely surround the Plant Hammond property. The water will be 10 feet deep in the power supply building for intakes to a pulp mill plant just upstream. Cabin Creek between the two plants and Beech Creek southeast of the mill will be flooded and cutting off access to the local roads.
587	Widespread and major inundation flooding occurs upstream and downstream from Plant Hammond. Most of the access road behind the plant will be flooded up to 14 feet deep in some locations. Flood waters associcated with Cabin Creek will surround the Plant Hammond property. The water will be 8 feet deep in the power supply building for intakes to a pulp mill plant just upstream. Cabin Creek between the two plants and Beech Creek southeast of the mill will be flooded and likely affecting access to local roads.
585	Widespread and major inundation flooding occurs upstream and downstream from Plant Hammond. Most of the access road behind the plant will be flooded up to 12 feet deep in some locations. Flood waters associcated with Cabin Creek will surround the Plant Hammond property. The water will be 6 feet deep in the power supply building for intakes to a pulp mill plant just upstream. Cabin Creek between the two plants and Beech Creek southeast of the mill will be flooded and potentially affecting the local roads.
583	Major flooding expands with widespread inundation flooding upstream and downstream from the gage behind Plant Hammond. Most of the access road behind the plant will be flooded up to 10 feet deep in some locations. The flood waters will be 4 feet deep in the power supply building for intakes to a pulp mill plant around one half mile upstream from the gage. Cabin Creek between the two plants and Beech Creek southeast of the pulp mill plant will be flooded.
581	Major flooding continues with widespread inundation flooding upstream and downstream from the gage behind Plant Hammond. Most of the access road behind the plant will be flooded up to 8 feet deep in some locations. The flood waters will be two feet deep in the power supply building for intakes to a pulp mill plant around one half mile upstream from the gage. Cabin Creek between the two plants and Beech Creek southeast of the pulp mill plant will be backed up and flooded.
579	Major flooding begins upstream and downstream from the gage behind Plant Hammond. The access road near the intakes behind the plant will be under 6 feet of water. The boat ramp near the intakes and a small portion of an access road near and under the Georgia Highway 100 bridge will be under 9 feet of water. The flood waters will reach the foundation of a power supply building for intakes to a pulp mill plant just upstream from the gage. Cabin Creek between the two plants will begin to back up and flood.
577	Significant flooding continues in the woodlands and fields along the river upstream and downstream from the gage behind Plant Hammond. The access road near the intakes behind the plant will be under 4 feet of water. The boat ramp near the intakes and a small portion of an access road near and under the Georgia Highway 100 bridge will be under 7 feet of water. The water level will approach the foundation of a power supply building for intakes to a pulp mill plant around one half mile upstream from the gage.
575	Moderate flooding begins. Significant flooding occurs in the woodlands...fields and pasture along the river upstream and downstream from the gage behind Plant Hammond. The access road near the intakes behind the plant will be under two feet of water. The boat ramp near the intakes and a small portion of an access road near and under the Georgia Highway 100 bridge will be under 5 feet of water.
573	Minor flooding continues to expand further into the woodlands...fields and pasture along the river upstream and downstream from the gage behind Plant Hammond. The access road near the intakes behind the plant begins to flood. The boat ramp near the intakes and a small portion of an access road near and under the Georgia Highway 100 bridge will be under 3 feet of water.
572	Minor flooding continues in the woodlands...fields and pastures along the river upstream and downstream from the gage behind Plant Hammond. The water reaches a low lying portion of a parking lot near the intakes behind the plant. The boat ramp near the intakes and a small portion of an access road near and under the Georgia Highway 100 bridge will be under two feet of water.
570	Flood stage is reached. Minor flooding begins of woodlands...fields and pasture along the river upstream and downstream from the gage behind Plant Hammond. A boat ramp near the intakes of the plant will be under water. A small portion of an access road near and under the Georgia Highway 100 bridge will begin to flood.
568	Bankfull conditions are reached upstream and downstream along the river from the gage behind Plant Hammond.
