Web-based Flood Chronology of the Carson River basin, California and Nevada, from 1852 to the Present

As new areas are developed to accommodate growth, communities are increasingly faced with the need to develop in flood-prone areas. Current efforts by the State of Nevada Floodplain Management Program, Nevada Division of Water Resources (NDWR), to support the Federal Emergency Management Agency's (FEMA) Map Modernization program, have been to act as a point of contact at the State level in communicating mapping needs for Nevada communities. In conjunction with floodplain mapping, NDWR has identified the task of compiling flood-hazard information in a format accessible and understandable to the general public and Federal, State, regional, and local agencies. The Nevada Floodplain Management Program considers it essential to make historical flood information publicly available, particularly for river basins with significant current and future population growth. The U.S. Geological Survey with the support of FEMA through NDWR's Floodplain Management Program has developed a web site to make historic flood information for the Carson River Basin publicly available. The web site contains information to help the general public in understanding the extent and frequency of flood hazards and risks in the Carson River Basin. Available information on specific flood events may include photographs, video clips, and links to related web sites, flood-frequency analyses, meteorological data, narratives, and streamflow data. USGS Fact Sheet 2006-3102 provides additional information, and the URL for this web site is http://nevada.usgs.gov/crfld/.
