35	Water is to the lowest portion of the downstream bridge at FM 622.
34	Major lowland flooding occurs. Water is completely covering the new bridge.
28	Major lowland flooding. Water is to the lowest portion of the new bridge. Low water crossings are inundated with several feet of water, likely cutting of residents.
22	Water is to the lowest portions of the upstream FM 237 bridge over Twelvemile Creek.
21	Major lowland flooding occurs, and cuts livestock off and potentially drowns them well away from the creek. Most roads and low bridges near the river are severely flooded and are dangerous.
17	Major lowland flooding extends well into the flood plain, cutting off livestock. Roads and low bridges near the river are flooded and are dangerous.
16	Moderate lowland flooding. Flooding of secondary roads and low bridges.
15	Minor lowland flooding reaches secondary and primary roads and low bridges.
14	Bankfull stage occurs. Flow reaches into the lowest flood plain.
