Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
30 or 9.1 meters, major lowland flooding occurs. Water is several feet deep over most of the mall and customs parking lots. The lowest residences are threatened and roads and low bridges become very dangerous.
28 or 8.5 meters, the flow reaches the height of left bank. Flow exceeds left bank near the gauge. Most of customs and mall parking lots are inundated downstream in Laredo. The lowest residences are threatened in Laredo and Nuevo Laredo. Livestock, pumps, and equipment in the river channel are flooded
24 or 7.3 meters, moderate lowland flooding occurs, and cuts off livestock, irrigation pumps, and equipment above eagle pass to below Laredo. Autos and trucks flood in the customs and mall parking lots downstream in Laredo
18 or 5.5 meters, flow reaches the height of the right bank. Livestock and equipment flood in the channel and low banks below eagle pass to below Laredo. Autos and trucks flood in low areas of the customs parking lot downstream in Laredo
16 or 4.9 meters, overbank conditions occur over the low areas of the flood plain
10 or 3.0 meters, this is the caution stage for pumps and livestock in the channel
