20	Major flooding continues of the Northwood Country Club Golf Course upstream from Club Drive...and in the woodland areas downstream through the merging with the Yellow River. The water level begins to flood portions of Club Drive near the bridge and will likely washout the banks and road on either side of the bridge. The USGS monitoring station will be under one foot of water and alternative measuring will be necessary. Yards of homes near the creek will be completely flooded with water entering houses.
19	Major flooding begins with widespread inundation of the Northwood Country Club Golf Course upstream from the gage on Club Drive...and in the woodland areas downstream through the merging with the Yellow River. The water level begins to flood portions of Club Drive near the bridge and will likely washout the banks and road near the bridge. The water will also reach the bottom of the USGS monitoring station. Yards of homes near the creek will be completely flooded with water entering some houses.
17	Significant flooding continues to expand further into the Northwood Country Club Golf Course upstream from the gage on Club Drive...and in the woodland areas downstream from the gage...and for the next four miles until the creek merges with the Yellow River. The water level reaches the bottom of the bridge on Club Drive and erosion of the banks near the bridge will occur. Backyards of homes near the creek will be flooded.
15	Moderate flooding begins. Significant flooding develops and expands further into the Northwood Country Club Golf Course upstream from the gage on Club Drive...and in the woodland areas downstream from the gage...and for the next four miles until the creek merges with the Yellow River. The water level will be just two feet under the bridge on Club Drive and erosion of the banks near the bridge will begin to occur. Backyards of homes near the creek will begin to flood.
13	Minor flooding will continue to expand further into the Northwood Country Club Golf Course upstream from the gage on Club Drive...and in the woodland areas downstream from the gage...and for the next four miles until the creek merges with the Yellow River. An old concrete golf cart bridge around 300 feet downstream from the gage will be around two feet under water.
11	Flood stage is reached. Minor flooding will occur in portions of the Northwood Country Club Golf Course upstream from the gage on Club Drive...and in the woodland areas downstream from the gage and for the next four miles until the creek merges with the Yellow River. An old concrete golf cart bridge around 300 feet downstream from the gage will begin to flood.
9	Bankfull conditions are reached upstream and downstream from the gage at Club Drive. Portions of the Northwood Country Club Golf Course will begin to flood upstream in low lying areas near the creek.
