Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
46 Several homes flood in the Colorado River flood plain below Del Valle to Bastrop and along Onion Creek above the Colorado River confluence are severely flooded. Numerous streets and roads are extremely dangerous. Major flooding extends well into the flood plain destroying equipment and livestock.
44 Major flooding approaches homes in the flood plain below Del Valle to Bastrop. Equipment and livestock should be moved from the flood plain to below Bastrop. Secondary and primary roads and bridges are flooded severely and very dangerous to motorists.
42 Major flooding approaches the lowest residences along the Colorado River below Del Valle. Residences in the lower reach of Onion Creek are vulnerable to flooding as the Colorado River backs up the creek and adds to runoff down Onion Creek. Livestock and equipment should be moved from the flood plain below Austin to Bastrop. Lowest homes flood near Webberville.
40 Lowest homes in the flood plain below Longhorn Dam to above Bastrop Flood. Livestock and equipment should be moved from low areas of the flood plain below Lake Travis to below Bastrop. Roads and low bridges in the flood plain flood severely and are dangerous to motorists.
38 Moderate flooding approaches the Colorado River ranchettes in the southwest quadrant of the confluence of the Colorado River and Dry Creek. Lowest homes downstream below Austin flood. Livestock should be moved from vulnerable areas of the flood plain.
36 Several homes are threatened as the Colorado River backs up Onion Creek. Any additional flooding down onion creek may flood homes near the confluence with the Colorado River. Livestock should be moved from vulnerable areas of the flood plain below Austin. Lowest homes below Austin flood.
35 Lowest homes and apartments near the Colorado River and the lower part of Onion Creek are threatened. Residents should monitor NOAA All Hazards Weather Radio for developing flood warnings. Livestock can be cut off in low areas below Austin. Lowest homes below Austin to Bastrop flood.
33 Minor lowland flooding reaches low areas of the flood plain. No significant damage occurs at this level near Austin but livestock should be moved from low lying areas downstream. Lowest homes below Austin to Bastrop are threatened.
31 Flow is well into the flood plain below Lake Travis downstream. Livestock should be moved from low areas of the flood plain downstream below Austin.
29 Flow is into the lowest sections of the flood plain.
27 Flow is in the lowest sections of the flood plain.
25 Flow exceeds the lowest sections of the banks.
