National Weather Service's Office of Hydrology (OH) and its Hydrological Information Center offer much information on floods and other aquatic disasters. Besides information about the various components of the office, the OH site offers current and historical data including an archive of past flood summaries, information on current hydrologic conditions, water supply outlooks, as well as an Automated Local Flood Warning Systems Handbook, Natural Disaster Survey Reports, and other scientific publications on hydrology and flooding. The site also provides information and order forms for the office's video on the dangers of Low Water Crossing. The Hydrological Information Center subsection describes the mission of the center, provides much additional information on flood impacts, and offers extensive flood impact data on deaths and economic losses.
