Climatic variations in precipitation are unpredictable, but flood-inundation maps and interactive mappers can provide useful information to the public and planning agencies on historical and potential areas of impact with the goals to reduce damage to property and loss of human life. Peak streamflow, high-water marks, and flood-depth measurements are just some of the data that the USGS collects during flood events. The data releases on this page provide measurements used to create flood-inundation maps and may also contain geospatial coverages and the final maps presented in published scientific reports. In addition, the USGS Flood Inundation Mapper for selected sites in the United States can be accessed here: https://wimcloud.usgs.gov/apps/FIM/FloodInundationMapper.html.
