35	Disastrous flooding continues with the west approach to the Highway 59 bridge inundated and closed. Several homes in the Lavaca River floodplain above Highway 59 into northern Jackson County are flooded. Hundreds of head of livestock may be cut off and drown in low areas.
34	Disastrous flooding continues with water is to the low steel of the Highway 59 bridge. Several homes in the floodplain above highway 59 are flooded with widespread inundation of primary and secondary roads. Hundreds of head of livestock may be cut off and drown in low pasture areas.
33	Disasterous flooding occurs with the lowest homes above highway 59 flooded and there is several feet of water over secondary roads and low bridges. Flow is within inches of spilling over the approaches to the Highway 59 bridge. Hundreds of head of livestock above Highway 59 to below Hallettesville may be isolated and drown.
30	Major lowland flooding continues with the river over one half mile side near the Highway 59 bridge. Numerous roads and bridges in the floodplain are inundated and closed. Livestock are isolated well into the floodplain.
28	Major lowland flooding begins with the river one half mile wide near the Highway 59 bridge. Primary roads and low bridges are flooded and secondary roads are closed. Livestock are isolated with widespread inundation of crop and pasture land.
25	Moderate lowland flooding begins with the river one third of a mile wide near the Highway 59 bridge flooding secondary roads and bridges along the river. Livestock are isolated and potentially drown.
23	Flooding along the Lavaca River reaches hundreds of yards into the lower floodplain backing up sloughs and low areas. Minor roads and near the river flood and livestock are isolated.
22	Flooding along the Lavaca River reaches well into the lower floodplain backing up sloughs and low areas.
21	Minor lowland flooding begins with flow backing through preipheral channels adjacent to the river and reaches into sloughs and low areas.
20	At levels above 20 feet flow exceeds the lowest sections of both banks.
