National Flood Summary
By US Geological Survey (USGS). 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. 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.

National Water Information System (NWIS)
By US Geological Survey (USGS). Provides access to water-resources data collected at approximately 1.5 million sites in all 50 US States, the District of Columbia, and Puerto Rico. It includes information on the occurrence, quantity, quality, distribution, and movement of surface and underground waters.

San Francisco Bay Region Geology and Geologic Hazards
By US Geological Survey (USGS). The San Francisco Bay region is home to 7 million people whose lives are intertwined with some of the most complex and active geology in the world. With heightened public awareness about earthquake hazards on the 100th anniversary of the 1906 San Francisco earthquake, the U.S. Geological Survey, in cooperation with the California Geological Survey, has prepared three maps of the San Francisco Bay Area designed to provide a new look at the geologic history and hazards of the region: Geologic Map, Quaternary-Active Fault Map, and Liquefaction Susceptibility Map.
