758	Major flooding begins. Extensive flooding occurs along the creek downstream from the Lake Horton Dam to the Flint River. The dirt service road next to the USGS tailwater gage will be under 7 feet of water. The flood waters will have topped the Lowery Road bridge and county officials will have it closed. The USGS gage house will be under two feet of water with a loss of data transmission. A home at the end of Cheshire Circle will be flooded.
757	Significant flooding expands along the creek downstream from the Lake Horton Dam to the Flint River. The dirt service road next to the USGS tailwater gage will be under 6 feet of water. The flood waters will be hitting the Lowery Road bridge with possible erosion to the sides. The road will begin to flood and county officials will likely have it closed. The USGS gage house will be under a foot of water with a loss of data transmission. A home at the end of Cheshire Circle will begin to flood.
756	Moderate flooding begins. Significant flooding occurs along the creek downstream from the Lake Horton Dam to the Flint River. The dirt service road next to the USGS tailwater gage will be under 5 feet of water. The water level will reach the bottom of the Lowery Road bridge and county officials may have it closed. Flood waters will have submerged the USGS gage house with a loss of data transmission. A large portion of the yard of a home at the end of Cheshire Circle will be flooded.
754	Minor flooding expands along the creek downstream from the Lake Horton Dam to the Flint River. The dirt service road next to the USGS gage will be under 3 feet of water. The water level will reach the bottom of the bridge supports for Lowery Road. Flood waters will affect the USGS gage house with a loss of data transmission likely. A portion of the yard of a home at the end of Cheshire Circle will begin to flood.
753	Flood stage is reached. Minor flooding begins along the creek downstream from the Lake Horton Dam to the Flint River. The dirt service road next to the USGS tailwater gage will be under two feet of water. Flood waters will reach the bottom of the USGS gage house with a possible loss of data transmission.
751	Bankfull conditions are reached along the creek downstream from the Lake Horton Dam to the Flint River. The dirt service road next to the USGS tailwater gage and low lying woodland areas will begin to flood.
