Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
29 Major flooding covers the flood plain inside the levees - flow approaches lowest homes upstream in Brownsville - low roads and bridges near the river are flooded and become dangerous - flood prone residents should monitor NOAA weather radio for developing heavy rain and flooding
27 Moderate lowland flooding covers much of the flood plain inside the levees - lowest secondary roads and low bridges are flooded near the river - property including irrigation pumps, farm equipment, and livestock should be moved out of the flood plain. Lowest homes are threatened.
26 The river is into the lowest areas of the flood plain inside of the levees - no significant damage occurs at this level but flood prone residents or property owners should monitor the level of the river
24 The river exceeds the lowest sections of the banks inside the levees
