By Raymond M. Slade, Jr., and John Patton


Many Texas storms represent some of the largest storms in the world. Flooding from large storms has affected Texas throughout its history, causing many deaths and much economic loss and hardship. Floods occur regularly in Texas, and destructive floods occur somewhere in the State every year. Many of these floods are destructive because they often occur in areas where extreme flooding had not occurred for many years. These floods often are perceived as unexpected or even unprecedented because their peak water-surface elevations (stages) can greatly exceed those of past floods. This report documents major and catastrophic storms and floods in Texas. Storms can be viewed by date, county, or maximum precipitation.
