USGS National Flood Summary Describing Major Floods and Damages in the U.S., Including Puerto Rico, Now Available on World Wide Web
Floods are the most frequent of all catastrophic natural hazards, costing an average of $6 billion in losses annually and threatening lives and property in every state. The U.S. Geological Survey has made the National Flood Summary information from 1970-1998, including maps and data, available on the World Wide Web at http://ks.water.usgs.gov/Kansas/floodsummary. The web site provides the public a tool to compare current or possible flood conditions with past historical flood information by state and year, as to magnitude, cause, loss of life, damage, and cost for this 28-year time period. Included in the National Flood Summary website is the latest volume of the National Flood Summary series describing significant floods in the U.S. and Puerto Rico from 1994-1998, and is available at http://pubs.water.usgs.gov/sir2005-5194/.
