This volume is a compilation of significant floods that occurred at streamgages throughout the United States and Puerto Rico from October 1, 1993, through September 30, 1998. A significant flood in this report refers to a peak-flow discharge (instantaneous or time averaged) that is in the top 5 percent of all the annual peak flows recorded at streamgages during their total period of record. Most of these floods are approximately equal to or greater than the 20-year recurrence interval flood (0.05 probability of occurrence in any 1 year) for that streamgage.
A summary of the most devastating floods according to number of lives lost and amount of damage is provided for each water year from 1994 through 1998. Significant interstate floods also are described. For each year, national maps are provided showing percentage of streamgages in each State recording the significant floods and standardized deviations from long-term (1950–95) mean precipitation.
Compilations arranged by State for each of the 50 United States and Puerto Rico also are presented. Each State compilation includes: (1) State maps to locate the streamgages recording significant floods and (2) tables of data that allow the reader to compare each significant flood during water years 1994 through 1998 with the maximum flood for the entire period of record at each streamgage.
